Installing and connecting cameras

As an outdoor camera, we take any digital IP camera with a good resolution and a waterproof case, and place it so that, if necessary, you can distinguish the faces of the “visitors”.

Network IP camera with Wi-Fi, motion sensor and IR illumination Hikvision DS 2CD2432F-IW.

We install a small home IP camera inside the house. For example, let’s take a model from the manufacturer Hikvision: DS-2CD2432F-IW, with a built-in hardware motion sensor, which, unlike software, allows you to avoid false alarms. Also, this device has the ability to two-way audio communication, and when integrated with a smartphone using a special program, you can say something, and the camera speaker will reproduce what was said.

The camera can also be purchased cheaper from the manufacturers Hikvision, D-Link, Samsung, Panasonic, Phillips, Falcon Eye, or another popular manufacturer. the price for such cameras ranges from 4 to 12 thousand rubles.

To connect cameras, you need to know their login, password, and IP address, which can be determined using a special program (Hikvision calls it SADP, and is included in the kit). The login is usually admin, and the password is 12345, or a combination of several zeros. We connect cameras to a DVR or router using a UTP cable, via a wi-fi network, or we combine options. For example, the above-described indoor camera can be connected wirelessly via wi-fi, and the outdoor camera can be connected via a cable. In order not to pull an extra power cable, even when choosing a device, you need to check the availability of power via a network Ethernet cable (PoE technology. Power over Ethernet), because then you will have to “shamanize” with twisted pair, or buy PoE adapters.

To implement video surveillance in the country, alternative power sources are often required. Read about autonomous video surveillance for monitoring remote objects.

Best Location To Install CCTV Camera | इस Field के Professional बने | Bharat Jain

We set up the internal camera so that the recording starts only when movement occurs, this will significantly save disk space and our own time, since there will be practically no movement in the house, and it will be quite enough to view tons of unnecessary materials in the future. tiresome.

We also need to set up the sending of alarm messages to an email address or mobile phone, with the attachment of snapshots of what is happening for a quick assessment and response to the situation. All these functions can be enabled when setting up the equipment according to the attached instructions.

We connect the outdoor camera via UTP cable to the recorder or directly to the 3G modem (router), depending on the option chosen, and also configure all the necessary functions.

In order not to miss anything important around the edges of the camera’s view, we set it up so that the recording is carried out around the clock, and when movement occurs in the frame, these moments in time are marked with special flags on the general recording tape.

Equipment selection

In order to choose the right equipment for installing video surveillance in the country, you need to know all the necessary technical points related to this issue.

Approximate location for installing CCTV cameras

Place of installation of cameras. When choosing cameras, it is necessary to start from the place of their planned installation: if you are going to install the camera outdoors for a general overview of the site, you need to purchase a device with a protective dust and moisture resistant housing (protection class IP 66). For indoor installation, a regular home IP camera with wi-fi is suitable, if necessary.

Sensitivity. An important characteristic of the camera is the light sensitivity of the matrix and the presence of IR illumination. Cameras with high sensitivity (0.01. 0.001 lux) allow video surveillance in poor lighting conditions, and with the help of infrared illumination, video surveillance can be carried out even in complete darkness. Due to the fact that the least amount of noise in poor lighting will occur in black and white shooting mode, for monitoring in low light conditions, it is necessary to purchase devices that can switch from color mode to monochrome at dusk (day / night function).

Resolution. In order for the camera image to be able to distinguish the faces of people visiting the summer cottage, we need devices with high-resolution recording. Modern IP cameras with HD and Full HD resolution can provide good picture quality. They are capable of giving a picture much clearer and more detailed than analog cameras with a resolution of 420. 700 TVL. But after the appearance of the AHD format, it is possible to use analog cameras of high resolution, comparable to IP.

Viewing angle. To provide a general overview of the territory or the room of a country house, it is worth giving preference to cameras with a good viewing angle and a short focal length. In cases where it is necessary to monitor only a certain object, buy cameras with a long focal length or varifocal lens to adjust the desired angle of view on site.

Cable. When connecting analog cameras, in most cases, a coaxial cable is used. due to the presence of a shielded braid, it provides minimal signal loss and protection from interference. Analog devices, along with digital ones, can also be connected via a network UTP cable, using video balloon transceivers. To connect digital IP cameras, a UTP “twisted pair” cable is used, with which you can carry out both signal transmission and power supply of devices.

Video recorder. If you need to keep a 24/7 recording of what is happening, you may need a video recorder and a hard drive. An important point is the number of DVR channels. how many cameras you can connect to the system depends on them. For example, a miniature video recorder with 4 channels and a 1 TB hard drive will be enough for a summer residence. The external hard drive must be able to be powered from the mains through its own separate power supply.

To begin with, it would be nice to ask the question of the advisability of installing video surveillance in the country. if your site is located in some sparsely populated wilderness, with a large number of abandoned summer cottages, then there is a high probability that the equipment will simply just resist, and then write was gone. If your “hacienda” is located in a relatively well-populated summer cottage complex, and there is also a good house on the site, then you can try to install a couple of cameras.

Cloud solution with LTE station for summer cottages

Since in most cases at a summer cottage the signal quality of the cellular network leaves much to be desired, not to mention good 3G / 4G reception, it is necessary to purchase a high-quality signal amplifier. Thanks to the installation of an amplifying LTE station, today it is possible to solve the problem of poor mobile Internet in the country, and it is easy to implement remote video surveillance with further viewing from any device connected to the Internet. At the same time, the task of setting up and connecting the entire system is greatly simplified if you additionally use a cloud service. At the moment, there are similar LTE antennas and cameras, already ready to work with the cloud service. Consider the proposals of the IVideon company.

There is a built-in 4G modem inside the station, so all you need is an outlet and a home router. The antenna connects to the router, from which there are wires to the cameras. Power to the LTE station is supplied by the PoE injector via the same cable as the signal, so there is no need to carry additional power wires. The connection diagram is shown on the right.

So if you are thinking about remote video surveillance for a summer residence, but do not want to bother with the selection of equipment and complex and time-consuming setup of the system, then the IVideon solution is exactly for you. all you need is to place the antenna and cameras in the appropriate places, and connect all the components systems between each other, then download a special application for iOS or Android, and with its help, thanks to prompts and intuitive steps, configure the cameras for broadcasting the video stream to the cloud service. That’s all, the system is ready to go.

Video surveillance system for summer cottages

CCTV cameras by themselves will not protect your dacha from the penetration of unwanted guests, but will only help to identify the person and make it easier to catch pests. For those who are wondering about the implementation of video surveillance for a summer residence, experts advise deploying a full-fledged security system, which will include the following elements:

• CCTV cameras themselves with the necessary equipment;
• Fire and burglar alarms in combination with motion and smoke sensors, with sending an alarm message to e-mail or mobile phone;
• Sound alarm triggered when movement occurs or the door is opened.

Remote access

An example of a 3G router is TP-Link MR3020, the cost is about 3 thousand rubles.

If you want to have both remote access to cameras and record what is happening in the archive, we need both a video recorder and a 3G modem. In this case, we connect all cameras to the recorder via UTP cable, and the recorder to the router, and set up remote access.

It is worth saying a few words about the possibility of implementing video surveillance for a summer residence via the Internet. if the coverage of the cellular network signal in your area leaves much to be desired, then you can forget about this option, since the image quality will suffer very much with a bad signal, and breaks may occur communication. So in such cases, it is better to do with a simple video recorder with recording on a hard drive.

For remote video surveillance, you can use a cloud service from the domestic company IVideon, with the ability to connect 15 cameras for free. You can read about setting up remote monitoring through the IVideon website here. Through this service, you can keep an archive on the site, or record what is happening on a computer remotely using a special developer program IVideon Server. There are also iOS and Android smartphone apps so you can connect to your cameras right from your mobile.

In general, now manufacturers, as a rule, take care of creating their own free cloud services to integrate with their cameras, so before choosing third-party programs, find out if your camera manufacturer has similar developments.

To implement a small video surveillance system for a summer cottage, you can do with two cameras. one will have a protective case, and be located on the street in the direction of the landings, and give a general picture of what is happening on the site, the second is placed opposite the front door inside the country house to identify individuals entering inside.

By the way, an important point is the presence of electricity on your site, otherwise even the most promising undertakings may be doomed to failure, because in the absence of it, you will need alternative power sources. car batteries, wind generators, solar panels, uninterruptible power supplies, etc.. and this is an additional cost of effort, time, and money.

To create a video surveillance system in the country with our own hands, we need the following elements:

• Two high-definition IP cameras. one outdoor, the other indoor;
• UTP cable for connecting cameras;
• To make video surveillance at the dacha via the Internet, we need a 3G modem router, which can be purchased from a mobile operator along with a SIM card;
• Mini digital video recorder and external hard drive for 24/7 recording.

Rating of the best video cameras for outdoor surveillance

Where to install video cameras

If there are scattered structures on the site, then observation points should be located so as to cover all possible approaches and potential places of intruders’ penetration. The field of view of the devices should include windows, doors, street gates and gates, the perimeter of the fence, pedestrian paths and open areas of the courtyard.

Modern outdoor cameras, according to the coverage area, are:

• Stationary, directed to one point. Such devices can track a sector of the territory in 90 o. 120 o. They are recommended to be placed where it is required to focus attention on any specific object. the front door to the house, street gates, wickets, etc.
• Domed with a wide coverage area. Their viewing angle can range from 180 to 360 degrees. It is better to install such cameras in open spaces. thanks to this, you can cover a maximum of the territory with one surveillance device.
• Swivel. This type of surveillance camera is equipped with a servo drive for remote control and is intended for installation on the corners of buildings. A PTZ video camera installed in this place can alternately monitor two walls of the house at once. Therefore, to track the entire perimeter of the building, two devices installed at its opposite corners will be sufficient.

It can be controlled manually by the user himself or by a smart home processor. So, outdoor video surveillance cameras with a motion sensor, when a suspicious object appears in the protected area, transmit a signal about this to the central hub. In response, the smart-house system, using servo drives, adjusts the viewing angle so that the observed object remains in the field of view at all times.

The light sensitivity of optics is also of great importance. On the market, you can find devices with an indicator from 0.1 to 0.005 lux. For outdoor video surveillance, it is necessary to monitor the protected area around the clock. Devices with high light sensitivity are installed to monitor poorly lit areas at night. Outdoor cameras with IR illumination are also great for this.

The infrared spectrum makes it possible to monitor the protected area even in complete darkness. on a moonless night in the absence of artificial lighting. All of them are equipped with an automatic transfer from night to day observation mode. Despite this, it is necessary to choose a place for installing 24-hour surveillance cameras in such a way as to avoid direct rays of the sun or the light of searchlights hitting the lens. This can reduce the quality of the resulting image.

CCTV camera HiWatch DS-T506

The analog wired HiWatch camera belongs to the category of outdoor cylindrical devices. It has a metal vandal-proof body, and a visor above the lens protects it from the sun’s rays. The lens itself is varifocal, capable of changing the focal length from 2.8 to 12 mm, thereby increasing the resulting image by 4 times if necessary.

The image is transmitted over a coaxial cable. Has a moisture resistance class IP-67, which allows them to be installed in open spaces not protected from precipitation. Thanks to IR illumination, the camcorder is capable of night recording at a distance of up to 40 m. Specifications:

• Resolution. 5MP.
• Focal length. 2.8. 12mm.
• Operating temperature range.40 o. 60 o.
• Weight. 900g.
• Dimensions. 27 x 9 x 8.5 cm.
• Price. from 4.6 to 7.6 thousand.

How many cameras need to be installed?

The number of cameras in the local area directly depends on its size, coverage area of ​​each device and other additional features. Therefore, their number is calculated on an individual basis, based on the characteristics of the local area. When choosing, you need the following nuances from Honor:

• Clarity of resolution. The higher it is, the more “long-range” the camera will be. Today on the market of video surveillance systems there are devices with a resolution of 1 to 5 megapixels. The more space you want to cover with one camera at a distance, the more powerful a video camera you need to buy. An inexpensive 1MP camera is enough to view the site in front of the front door. To obtain a detailed image of objects 30-50 meters away, it is better to choose more powerful optics. 4-5 Mp.
• The relief of the site. The number of observation points should be such as to block all possible access routes to the house, garage or other objects. In this case, buildings and plantings should not block the view. In such a situation, it is better to put a couple of additional video devices in order to eliminate the “blind spots”.
• The importance of the protected object and the number of access points to it. High-quality CCTV cameras are by no means cheap. If you want to save money on the installation of a video security system, determine the priority areas. For example, it is not entirely necessary to install a large number of cameras to cover all ancillary buildings on the site. sheds with agricultural implements, greenhouses, beds. But you should not save on the protection of a house or garage. It is better to place so many observation devices here to view all doors and windows in detail.

CCTV camera Dahua DH-HAC-HFW1000RP-0280B-S3

This outdoor surveillance camera records video in high definition HDR mode. Capable of transmitting 4 signals simultaneously (sound, image, power and control) over one coaxial cable. By design features, it belongs to cylindrical models with a fixed lens direction. The device is controlled using a multilingual OSD menu.

The signal, thanks to the used HDCVI technology, is transmitted at high speed over coaxial cable without distortion with a resolution of:

How to choose an outdoor CCTV camera?

An outdoor CCTV camera is an important element of a smart home security system. However, in order for the cameras to work as efficiently as possible, Honor has a number of nuances. First of all, you need to choose the right device itself, based on its technical capabilities and performance characteristics. The number of cameras and their installation locations are selected so that they cover as much of the surrounding space as possible without leaving blind spots. All these features of the installation of outdoor video surveillance systems will be considered in this article.

What is the best distance to install cameras

The distance between individual video surveillance equipment directly depends on the range of their action. It is important here to get a fairly clear image at an equal distance from two adjacent cameras. The maximum range is indicated in the technical specifications in the device’s passport. For example, modern outdoor video cameras with IR illumination have a range of about 30-50 m, both in the daytime and at night.

Connection options for outdoor cameras

By the method of connection, outdoor video surveillance cameras are divided into:

• Wired. The image from the device to the server is transmitted via fiber-optic communication channels. Currently, VGA-VGA channels are most often used to connect wired cameras to surveillance monitors.
• Wireless. Image transmission here is carried out using Wi-Fi, Bluetooth or GSM-module. This makes it possible to receive an image from the camera directly to the user’s mobile device.
• Combined. There are also models commercially available that can be connected to viewers both wired and wirelessly.

Saving the recording received from a wireless camera is possible on a dedicated server (including a “cloud” one) or a mobile device. There are also outdoor surveillance cameras with recording on a USB flash drive inserted into the device itself. Wired camcorders can transmit and record images only with the help of additional devices:

• TV tuner.
• Image Capture Video Cards.
• USB converter.
• DVR.

How to set up a video surveillance recorder

To monitor the territory, you need a fixing device and a device capable of forming an image and recording it. A convenient method is to install DVRs. Such a device captures the signal and records it. Correct configuration of the CCTV recorder provides the same performance as a standard surveillance system. At the same time, the installation is much faster.

Features of DVRs

The device is a mini-computer equipped with an input device. It records the signal, compresses it into the required format and writes it to the hard disk. The DVR can work with multiple cameras.

The memory capacity of the device is much higher than that of a camcorder with a memory card.

Video recorders are used when it is important to respond quickly to what is happening on the site and record the observation in order to further study the recordings and analyze.

Hard disk installation procedure in the DVR

The resulting image is written to the hard disk. Before setting up any CCTV camera, you first need to make sure you have a hard drive or install it if necessary. The algorithm is the same for all models.

• Unscrew the bolts holding the device cover and remove it.
• The hard carrier has mounting holes similar to those in the recorder board. They are aligned and the disc is bolted. The latter are included with the device.
• Find 2 stubs: red for signal transmission and red-yellow for power supply. Connect the ribbon cable to the disk.
• Install the cover and screw it on.

In the DVR, you can install a regular hard drive intended for a PC.

Local

There are 2 main options: connecting to a computer that has 2 network cards, or through a network switch. In the first case, they act like this:

• Connect the device to the PC with twisted pair wires.
• Enter the main parameters in the network settings and at the end go to “Local Area Connection”.
• Mark the Tcp / IP protocol and move the switch to the “Use the following IP address” position.
• In the interface of the DVR, go to the network settings and indicate the IP address. The last 2 digits of it must be different from the IP address of the PC.

The given algorithm is based on the Windows XP OS menus. In other operating systems, the order may be different.

Configuration via a network switch is performed in the same way and differs only in the pinout of the patch cord connector.

Connecting the recorder to a computer

The system will require the actual video recorder, cables for connection, a power supply, adapter connectors and a manual that describes how to connect and configure the device and CCTV cameras.

• unpack the equipment, find instructions and mounts for the hard drive;
• install and fix the hard drive;
• connect the video recorder to the monitor and its own power supply;
• connect the cameras and the recorder together through patch cords and special connectors;
• plug the device into the network and download.

If everything is done correctly, 4 windows and a registration form appear on the screen.

Network

This method involves establishing a connection between the modem and the DVR. The modem is pre-configured: you need to tell the device where to route the connection on the network. If the connection is direct, the settings received from the provider are simply entered into the “Network” menu.

• The connection is made only through Internet Explorer. Through “Internet Options” and “Security” go to “Trusted sites” and add the IP address of the DVR.
• In the address bar of the browser, indicate the static IP address provided by the provider, and press the Enter button. In this case, a window may appear prompting you to install some elements. The user agrees with this and expects their installation.
• Then the browser is restarted, the address of the registrar is entered again. In the window that appears, write the login and password, and then connect to the proposed port.
• When connecting for the first time, the user sees a window with 4 empty squares. To see the image, you need to click on the square and link it to the camera from where the image is received.

How to set up a video camera and a router, you can find out in the instructions.

Camera adjustment

Fine-tuning the CCTV camera allows you to adjust the observation mode: set filters, set the sector or search object, determine the sensitivity level.

By clicking on “Next step”, you get a menu in which the recording mode is set up. constantly, when the movement is fixed, on alarm. The recording schedule is also indicated here. In the desired channel, select the setting of the video surveillance modes by the recorder and indicate how the camera should operate on each day of the week and at different times of the day. This will significantly save.

The settings are saved. If necessary, connect a smartphone or other gadgets.

Defining the functions to be performed by the camera

The choice of device characteristics largely depends on the tasks assigned to a separate video surveillance point.

• the layout of CCTV cameras can include dozens of inexpensive devices located around the perimeter;
• the same problem can be solved with the help of expensive cameras equipped with a system of remote change of orientation and focusing. To do this, the tracking zones are selected, the automatic review programs are configured, the operator notification toolkit is provided.

However, based on planning the tasks to be performed by a single camera, it is possible to develop a schematic diagram of the location of individual devices. For each camera, based on the focal length of its optics, the angle of view, several effective zones are clearly defined.

The camera’s field of view can be conditionally divided into several segments:

• zone of confident identification of small objects;
• segment of face and medium-sized objects recognition;
• an area where it is possible with a high probability to identify the presence of a person (to distinguish it from a transport, an animal, and so on;
• a segment where only motion detection using software sensors or low visibility of the presence of objects is possible.

When calculating how to correctly arrange video surveillance cameras, it is recommended to use specialized software, for example, IP Video System Design Tool.

Design packages allow you to superimpose monitoring points on the building plan, specify the parameters of individual tracking devices, and get areas for solving various problems.

Viewing angle

Viewing angles, first of all, are selected depending on the tasks facing a separate monitoring point.

For example, outdoor surveillance cameras operating from a long distance should have a small value of the considered parameter.

This will significantly increase such important segments of observation as the area of ​​identification and confident identification of small objects.

Indoor devices are also selected according to the field of view and the tasks facing the video surveillance. For example, to monitor a large hall, it is enough to install one camera with volumetric panning and the functionality of cutting the generated image into separate segments.

At the same time, to identify small objects and read instrument readings, devices with a small viewing angle are needed, capable of forming a high-detail picture from a sufficiently long distance. In this case, it is recommended to use dome cameras with a positioning and focusing control system.

How to correctly position CCTV cameras: expert advice

The efficiency of the video surveillance system largely depends on the correct choice of the location of the cameras.

Fixation devices not only need to provide visibility with a minimum of blind spots.

Hikvision Security Camera Placement 4k

Knowing how to correctly position CCTV cameras around the house. you can guarantee the correctness of determining the distance to the object from the observation point, minimize picture distortions, solve other problems on which the quality of the received video stream and the coverage of the protected area depend.

Algorithm of actions when installing a CCTV camera

Before the final installation of CCTV cameras, it is important to determine the location of their installation and carry out preparatory work.

A short list of analyzed factors and eliminated shortcomings can be formulated as follows:

• For outdoor cameras, in accordance with their viewing angles, controlled areas are determined. They are placed in such a way as to minimize the area of ​​the space that does not fall into the lens.
• The placement of CCTV cameras designed to control the adjacent territory, if possible, is done so that it becomes possible to track a moving object in the proximity mode. That is, if the first monitoring point fixing the intruder is not able to provide a clear identification, the subsequent ones placed on the predicted route must form a picture with sufficient resolution for identification.
• The location of CCTV cameras should be chosen so as to exclude the effect of flare from strong sources. It can be the sun, night spotlights, headlights of passing or standing vehicles. To do this, select not only the installation points, but also the angles of inclination of the case and the height of the device.

The process of calculating video surveillance may vary depending on the complexity of the system and the tasks for which it is intended. However, in general, you can focus on several basic principles of organizing monitoring.

Placement height

The installation height of CCTV cameras depends on several factors.

• Protection of the device from the actions of vandals, accidental damage, unintentional or deliberate change of position by an intruder.
• Ensuring ease of maintenance (especially important for devices that require lubrication of moving parts or other preventive measures).
• Coordination of work and ensuring the same level of safety for auxiliary equipment (IR floodlights, power distribution boards, transmitters and signal converters).

Outdoors, the recommended installation height of cameras is 3 or more meters from ground level.

Equipment located low enough can be accessed from a ladder, while being reasonably well protected from vandals.

Indoors, it is recommended to mount the cameras on the ceiling. This will avoid accidental damage, water ingress, intentional or accidental change of position. In addition, ceiling-mounted devices have a maximum field of view and a minimum chance of obstructions for tracking.

When choosing the height and location of the cameras, several points should be taken into account, which will ensure that a high-quality image is obtained.

• Indoors, cameras are always installed in the direction of view from the window in order to minimize the effects of backlight, which are not always coped with by systems for expanding the color range.
• On the street, the place and height of the cameras are chosen so as to provide uniform illumination in the field of view or equal distances from the device to the light sources. This will allow you to correctly display the distance to moving objects, minimizing the so-called scale jumps.

If the sun or its reflection from mirror surfaces enters the lens of an outdoor camera installed at a height of 3 meters, the device can be mounted higher by changing the inclination of the body.

Benefits of Correct Installation of CCTV Cameras

The main thing that gives the correct design of the video surveillance system is the optimal solution to all the tasks of protection and monitoring of the situation.

The second plus important for the average user is significant savings.

• Reduced camera costs, reduced number of cameras.
• The number of DVRs and observation posts is sharply falling.
• Reduced data flow for visual or automated analysis.
• The length of the data channels is decreasing, their loading.

As a result of proper design, it is possible to reduce the number of cameras, involved personnel, while getting the maximum functionality of the video surveillance system.

Calculating the location of the cameras is not an easy task. Without the use of specialized software packages capable of the technical characteristics of the device, it is simply unrealistic to carry out optimal analysis and reduce the cost of purchasing equipment to the limit.

Therefore, the best option for obtaining a system with excellent characteristics would be to contact a company that provides design services.

Power supply

The issue of power supply of video cameras requires detailed study. It is necessary to select the correct cable type and size. If the power will pass through a twisted pair, the ratio of the diameter, length and characteristic impedance of the current-carrying conductor is taken into account, taking a margin of current value of 15-25%. This is due to the fact that manufacturers do not always indicate the full capacity of video cameras.

Cable routing has many nuances:

• It is preferable to lead wires into a pipe and let them into a trench. If underground installation is not possible, the line is laid by air, but with a length of no more than 30-50 m. Longer routes are often destroyed by lightning. At a long distance to the video camera, the cable is provided with lightning protection means.
• The bend angle of the coaxial line should not exceed 5 diameters. With a greater bend in the section, a rupture is guaranteed.
• If the length of the loop from the DVR to the camera is more than 150 m, it is necessary to install LF amplifiers. If the distance is 200-300 m, passive transceiver devices are connected via twisted pair. Above 300 m, active transceivers will be required.

Customization

When the cameras are already fixed in their places, the cable routes are hidden hidden across the territory, they start setting up the cameras. It is better to do this together. One person will work in front of the monitor, and the other will follow his instructions for changing the angle of the lens. Only then can the brackets be fully fixed.

High-quality equipment is always completed with a software disc and detailed instructions, so the setup process comes down to connecting a LAN, accessing the Internet and searching for a camera. The system issues device addresses automatically.

Then the user enters the IP-address of the camera on the server and makes the settings in the program window that opens. All devices on the network are installed in the same way. If the equipment supports remote access, additionally configure the gateway using the WAN interface.

The next stage is the creation of a control system. You can use standard software if you have experience with similar programs. It can be difficult for beginners to deal with all the subtleties.

Typically, the main menu of the control program includes the following items:

• “Search”. allows you to find files in the archive.
• “Configuration”. contains many sub-items to manage the entire structure.
• “Control”. designed to work with hard drives (they must be formatted during installation).
• “Setting”. sets the parameters of PTZ cameras and the connected monitor.
• “System”. allows you to track the history of actions.
• “Auto function”. allows you to reboot the system in case of crashes or failure.

A good option is to choose equipment from a manufacturer that offers camcorder applications. Such programs have a fairly wide functionality and are quite simple to configure.

Placement of the camcorder

There are many location options. The scheme depends on the area, the configuration of the building, the presence of fences, additional buildings, obstacles and other factors. You can roughly consider the placement of cameras in the video surveillance system of a country house. As a rule, 4 devices are located on the walls of the building and 1 under the roof, so that they can see the porch and gate. Before fixing the equipment, calculate the optimal tilt angle and height. It is necessary to display a picture on the screen and make sure there are no dead zones. When installing cameras, it is recommended to adjust the view in such a way that it covers the entire area from which it is theoretically possible to break the lens with a stick or a stone.

If you point the device towards the sun or a bright light source, it will quickly fail. When installing, analyze the movement of the sun during the day.

Also consider the location of the junction boxes. They must be protected from sunlight, precipitation, ice. The boxes are placed as high as possible so that they cannot be reached and broken from the ground.

Design

Even the simplest systems require project development. The drawings and diagrams define the architecture of video surveillance, the capacity of the structure with the ability to scale in the future, the need to install specific models of video recorders and other components. It is necessary to immediately decide whether the camera will connect to the computer or not (HDVR, NVR, etc.).

The project also calculates the level of illumination in the area, the required viewing angle, and the temperature range of operation. Opt for camera lenses, auxiliary components such as microphone, IR illuminator and others.

The designer determines the places for the installation of video cameras, the ways of laying the cable route. The wire should be kept away from power cables to avoid interference. Ideally, the route for transmitting video surveillance signals is laid parallel to the electrical wiring, but at a distance of 30-40 cm from it.

If the installation of outdoor video surveillance is planned, the project provides for grounding and grounding of the system. It is necessary to calculate the amount of solder material, fasteners, connecting elements, accessories, etc.

How to install a CCTV camera correctly

A video surveillance system is one of the most effective ways to ensure security at an object of any purpose. The structure includes many components that require professional installation, but it is quite possible to install a simple camera in an apartment or house on your own. It is only necessary to study the technical features of the process in advance.

Stages of installing a video camera

Professional installation of video cameras

Installing video surveillance on your own is a doable, but very difficult task. The main thing is that the system copes with its functions and does not become source of constant problems. In order for Honor to have all the nuances, it is necessary to pro Honor dozens of professional articles and forums, select components, develop a project, or at least draw up a diagram, working in constant contact with the equipment supplier.

PLACING OUTDOOR VIDEO SURVEILLANCE CAMERAS

When placing outdoor surveillance cameras, it should be borne in mind that each video surveillance object has unique design features. It can be cornices, ledges, balconies, pilasters, columns and other building structures.

This must be taken into account when installing outdoor cameras.

When positioning a camera to monitor a specific field of view, take into account the possible presence of blind spots (non-visible areas). They can be conditionally subdivided into two types:

• static. they are formed by such objects as: trees, structures or their elements, etc.;
• dynamic. they are formed by any moving objects, mainly vehicles, periodically falling into the viewing area of ​​the video camera.

In the first case, it will not be difficult to identify problem areas of work. It is problematic to foresee the time and place of the appearance of a moving object. In any case, the solution to the problem may be the installation of several CCTV cameras monitoring the same area from different locations.

In addition, if an image is recorded using a motion detector, moving objects can trigger its triggering, as a result unnecessary information will be recorded with a waste of disk space. This can be partially minimized by careful selection of detection zones and equipment sensitivity setting.

The entrance to a building is one of the tasks often solved by a video surveillance system. In this case, the placement of the video camera must ensure the identification of the subject of observation. At the same time, in addition to the possibility of identification by face, which can be closed in one way or another, it is necessary to ensure the receipt of information:

• about the general appearance of a person;
• about such parameters as: height, complexion, gait.

The optimal placement height for this case will be a value of 1.5-2 meters, and the best installation method is hidden.

In this case, the placement of cameras of the video surveillance system is made, as a rule, not on an external fence or specially installed supports. In this case, you should ensure:

• continuity of the observation area;
• control of the approach to each video camera.

METHODS FOR PLACING VIDEO SURVEILLANCE CAMERAS

Correct placement of CCTV cameras during their installation allows you to solve the main task of the video monitoring system, namely, to achieve maximum information content of the resulting video materials.

In addition, the optimal coverage of the monitoring area minimizes the required number of cameras. As a result. to achieve savings on the purchase of equipment.

The main parameters when placing a CCTV camera, regardless of whether it is indoor or outdoor, are:

• installation height;
• location in a controlled area;
• viewing angle.

In addition, it is imperative, especially when placing outdoor CCTV cameras, to exclude the possibility of unauthorized interference with the system. The most common hazard is mechanical damage to the camcorder.

This leads to partial loss of the image or complete failure of the device. In most cases, this is the result of acts of senseless vandalism or deliberate infliction of damage, the purpose of which is to suspend video surveillance in the controlled area in order to commit illegal actions.

Usually, stones, sticks and other improvised means are used. Modern video surveillance equipment is capable of detecting signal loss and generating a corresponding alarm signal. However, this is effective when placing the recording device in a room with constant presence of people, for example, at a security post.

Despite the fact that placing video cameras at a height inaccessible for direct access is one of the most effective methods, it has a very serious drawback.

As the height of the camera installation increases, its tilt angle will also increase to provide the required field of view. This usually leads to image distortion, interfering with the identification of an object or action.

The field of view is determined by the angle of view or the focal length of cameras (these parameters are interrelated). Incidentally, they also affect the degree of identification and effective observation distance. You can read about it here.

IP CAMERA PLACEMENT

The previously considered requirements for the placement of analog video cameras fully apply to IP cameras as well. However, there are several points that Honor should additionally follow when installing IP video surveillance. This mainly applies to outdoor installation.

It should be placed no more than 100 meters from the camcorder. If the distance of the camera installation from the room does not exceed the specified value, that the problem is solved simply. we place the switch inside the heated room and provide it with normal temperature and climatic conditions.

Otherwise, it is required to resort to installing a thermo (hermo) box and place additional equipment in it. In addition to the specified switch, this can also be a power supply. It is quite natural that the IP camera should be located as close to it as possible.

This is done at least in order to avoid unnecessary voltage losses with long lines. The same applies to cases of using PoE technologies.

If several video cameras are used, it is advisable to place them in such a way that all the additional equipment used can be installed in one box and the cameras can be connected to it according to the “star” scheme. Thus, you can achieve certain savings both on devices and materials, and on installation work.

In an amicable way, when installing a video surveillance system on the street, you should take care of providing protection against induced interference in any case. over, not only signal circuits are subject to protection, but also power lines. By the way, there is a separate material about the power supply of CCTV cameras.

Of course, the issues of protection against acts of vandalism are also present in this case, however, the following points are fundamental:

• ensuring the required viewing area and degree of detail;
• maximum preservation of the design of the premises.

By the way, dome cameras are most often used for indoor installation, since their design is optimal for the vast majority of premises.

Installation of video surveillance in the house

Choosing a DVR

The advantage of the video recorder is that it is completely ready for use immediately after connecting video cameras to it and performing simple settings. Most modern devices of this kind are equipped with the ability to remotely control the Internet or a local network. Also in favor of the DVR is its compactness and noiselessness.

The disadvantage of the device is the impossibility of self-repair. if it breaks down, reinstalls software or video capture card, you will have to go to a specialist.

Choosing a video recorder, you need to decide on the number of video cameras that will be installed at the facility. Experienced users recommend purchasing a device with several more cameras than you plan to connect.

The next important factor is the maximum capture speed. The ability to set the capture speed separately is in the device settings. by reducing its parameters, you can achieve a higher image resolution. Usually DVRs already have inputs for connecting a monitor and allow you to view previously recorded archives.

Choosing a video camera

The most important characteristic of a good video camera is its sensitivity, which depends directly on the size of the matrix. A camera with low sensitivity requires powerful infrared illumination and produces poor quality images.

Color cameras are less sensitive than B / W devices, so a day / night camera is ideal.

A sensitivity of 1 Lux at dusk gives a poorly readable and dark image, which is not helped even by the powerful infrared illumination, which illuminates only a short distance under the camera. The 0.01 Lux indicator allows the device to recognize the image well at night in the presence of IR illumination or a small outdoor light. The 0.0001 Lux indicator does not require additional illumination at any time of the day. a weak background light from the moon or a lantern is enough.

The sensitivity in modern video devices is often increased due to processor processing, so there may be no difference between cameras with indicators of 0.1 and 0.01 Lux.

Selecting a video camera for video surveillance should be based on the installation location and the purpose of shooting. For outdoor installation, it is advisable to purchase a device in a thermal casing that will protect it from precipitation. Covert video surveillance is best done using small-sized video cameras built into furniture or household appliances. You can also use wireless camcorders.

Video surveillance options

The first option is to install a dummy, which creates the appearance of a video camera at the facility. The effectiveness of such a technique is designed more to scare off than to a real result. therefore, it is still advisable to install a small video system that will conduct video surveillance on the most important areas of the house. It will be difficult for unexpected visitors to determine which of the cameras is the real one, and they are more likely to leave your home. You can also install a spotlight on the site.

It is possible to dispense with a partial installation of a video system if you need an overview of only one area. a parking lot, an entrance or a backyard. In this case, a video camera is combined with a video capture device (TV tuner) or a computer with modern software, which can save a much larger amount of recorded information than a modern video intercom.

You can also use IP cameras that connect through any network interface and have good technical characteristics with wide capabilities.

The third option is to install a full-fledged video surveillance system, which is necessary if you need an overview of a large area of ​​the house. To implement this option, you will need a high-quality video camera and a full-fledged video recorder. Also, instead of a registrar, you can use a powerful computer with the appropriate software, which will be in the house.

Installing a video camera without errors

Do not install a video surveillance device so that direct sunlight falls on its matrix. in this case, it is guaranteed to fail. Try to take into account the position of the sun at any time of the year or day, or even better, install the camera so that its field of vision is below the horizon.

When installing the camcorder, be sure to check the quality of the insulation, connections and protection of the device from rain, wind and other external influences.

Under no circumstances should the camera be installed behind window panes. they will distort the image and create a lot of glare on it.

Installation of CCTV cameras

Perhaps some of our readers found a time when they could safely leave their home unattended, being sure that no one would encroach on it. Times have changed a lot now, and leaving your home unattended is dangerous. Thanks to modern technology, even when you are far from home, you can leave it under supervision thanks to the installed video surveillance cameras. Below we will tell you about what kind of CCTV cameras are and how to properly install them.

What is needed for a video surveillance system

In order to organize a video surveillance system on your territory, you need to draw up a plan on which you will display the location of cameras and their number, the method of laying the cable to them, the location of the recorder, and other issues. To draw up a plan, you need to inspect the site and determine in which places you will install cameras.

Where to install cameras on the site

As a rule, cameras on the site are installed where it will be possible to see the places of possible penetration of intruders, as well as those parts of the site that, for one reason or another, you want to control. As a rule, a camera must be installed on the site opposite the entrance to see who comes to your site and into the house.

Often, many owners of country houses limit themselves to installing one camera at the entrance. If you need to install more cameras, then scatter them around the entire perimeter of the site. It is best to attach the camera to the house under a visor, thus, it will be safer, as it will be removed from the fence, and besides, there will be additional protection on top. The camera must be mounted at such a height that it is difficult to reach it both with your hands and with a long object with which you can turn it to the side.

As for the choice of where to install cameras in the house, we recommend installing them in the hallway, as well as in another place, for example, near the back door. This way you will be able to see who entered your house. We do not recommend installing video cameras in rooms, as the filmed material immediately becomes compromising on you.

We recommend purchasing box-type cameras as cameras for observation on the site. When choosing a camera, consider what kind of video it is recording:

• Color or black and white and what is the quality of this video;
• Does she record sound;
• How she shoots in the dark and what kind of lighting is necessary for her on the site so that the camera can clearly record the situation.

Pay attention to the fact that the camera is resistant to glare in the dark, that is, if intruders shine a flashlight at it, then the video does not have a bright white or yellow spot, but it is resistant to glare. If you buy one CCTV camera, the KSportal.ru editorial team recommends that you choose a video camera that can rotate 180 degrees.

For the installation of a video surveillance system in the house, we recommend choosing dome cameras, that is, those that are mounted directly on the ceiling. Also, study their characteristics before making a purchase.

Now for the registrar. Registrar. This is a device to which installed video cameras are connected, this device groups images from video cameras and transmits it to a TV screen, monitor or the Internet. A regular computer can be used as a recorder, which, in addition to the listed functions, will make it possible to record the captured video on a hard disk. You can also conduct both active video surveillance, which can be immediately displayed on the monitor, and passive, when recordings from cameras will be recorded on the hard drive. But that’s not all. Thanks to an Internet connection, you can remotely view online video from cameras on a work computer, laptop, tablet or even on a mobile phone.

On the Internet, you can find a wide range of video surveillance cameras. If you have components from an old computer, then you can build a computer on their basis and use it as a recorder, while on the Internet you can find a lot of software for arranging a registration system from CCTV cameras on a computer.

A 12V power supply is required to power the camcorders. As for the amperage of the power supply, it is calculated from the amount of amperage consumed by all installed cameras, with a margin. Thus, if the cameras installed in you will consume 2 Amperes in total, then it is better to take the power supply for 4 Amperes. The length of the power cable used must not exceed 40 meters, otherwise the power will “sink”.

We also recommend installing an uninterrupted power supply for the entire video surveillance system, since attackers, seeing CCTV cameras and if it is impossible to turn them off, most often take measures to de-energize the house. The presence of a continuous power source will allow for a certain time to autonomously power the cameras and the recorder in the event of a power outage.

Each camera needs to be powered by an electric cable, and use a coaxial cable to transfer the image.

How to install a CCTV camera yourself

Installing video surveillance in the country and in the house, with your own hands, begins with the installation of cameras. It is highly advisable that the cables that go to the camera do not go down the street. Firstly, this will extend their service life, since temperature drops, humidity and other natural factors will not affect them, besides, it will be very difficult for intruders to cut such a cable, even almost unrealistic, if the cables enter the wall at the place where the camera is attached and she covers them with herself.

Then lay the cables around the apartment. Try to hide the cable data, for example, run it through a false ceiling or in baseboards. It will be quite aesthetically pleasing, and besides, if intruders break into your house so that they cannot figure out where the recorder is located by the wire and do not erase the recorded video.

The installation of video surveillance at home also begins with the installation of cameras, from which the cable is laid to the recorder.

Installation and installation of video surveillance systems require a special approach to the choice of the location of the recorder. It is best to install it in a room that is locked with a key, and best of all in some secret closet.

When all cameras are reinforced, power is connected to them and a cable is laid from them to the recorder. proceed to setting up the equipment. The purchased recorder is configured according to the instructions, and the recorder in the form of a computer is configured according to manuals that are posted on the Internet on many resources.

And finally, a small recommendation for those who have installed a video surveillance system in their area. Be sure to hang a sign on the gate or fence stating that video surveillance is being conducted on the territory, this can become a deterrent factor for some intruders.
