Installing analog surveillance

While this type of system is already an obsolete standard, it is popular for its low hardware and installation costs. The applied image resolution is 0.4 / 0.5 / 0.6 Mp. Such systems are used at medium-sized facilities when only general control of the territory is required from the equIPment.

Observation systems capabilities

Any event on the trading floor is recorded in high quality on. Installation of surveillance will prevent up to 80% of possible thefts and will help in objectively investigating the remaining 20% ​​of incidents.

The technologies we use allow us to build a monitoring system for the Network. To control the object, you only need a cell phone, tablet or personal computer with Internet access.

Working with the archive of records

A convenient system for finding the desired record in the archive has been implemented. There is quick access to recording events that occurred 7, 14, 30 or 60 days ago.

Pairing with a motion detector

When the slightest movement appears in the camera’s field of view, the detector switch on the system for recording. A letter with a clIP or a screenshot taken according to predefined parameters will be sent to the e-mail of the owner of the protected object or the head of security.

Working in the dark

Twilight or even night is NOT a problem with modern cameras. IR illumination allows you to record high-quality images even in complete darkness.

Installation of AHD surveillance (CVI, TVI)

Such systems belong to the equIPment of a new generation; they are gradually replacing analog versions. The applied image resolution is 1.0 / 2.0 Mp. Possessing the optimal cost (as a rule, the average price category in the price list), with other similar characteristics, the equIPment is noticeably inferior in image quality to more modern IP systems. Such equIPment is popular as an option for replacing or some modernization of existing analog systems if it is impossible to fully replace the cable network.

Observation

Closed cable television system (surveillance system, CCTV) is a set of hardware and software tools that allow monitoring and recording of events at the facility.

Every year the business suffers millions in losses due to theft. Some companies accept this as an inevitable expense. Others cannot handle losses and go broke. Forward-looking and calculating leaders take action and oversee to protect their business, their employees and customers.

Thanks to the monitoring installation, you will be aware of everything that is happening with your business 24 hours a day. Nothing will go unnoticed. In the event of any incident, you can refer to the irrefutable record and take action, eliminating this once and for all.

How to set up and connect an IP surveillance camera?

So, everything you need has been purchased, installed, and you can’t wait to see what happens at home in your absence, while on vacation with a tablet in another country. Therefore the next step. setting up IP surveillance. For its implementation, it is good to have a general understanding of the construction of computer local and global networks based on IP-addressing. But even without knowing this specificity, the task can be solved. What awaits us? self-configuration IP cameras.

The capabilities of digital (network) surveillance cameras allow you to connect them to a network and receive from them according to the following scheme:

  • Through a router
  • Via computer
  • Through the registrar

We take into account whether the camera is wired or transmitting a signal via a wireless communication channel. In the first case, it is necessary to prepare a patch cord from a Category 5 UTP cable (twisted pair). Also, do not forget to install the wireless camera closer to the Wi-Fi access point. And of course, in addition to IP settings. remember about the possibility of setting frame resolution, recording rate, motion schedule (If it is a PTZ camera) and other options available for editing after the camera is displayed on the network.

Before you start connecting the equIPment to the network, you need to find out the network settings. Perhaps this is in two ways. Using the data provided by the Internet provider (ISP), or on the computer, select Start, type CMD in the search bar for programs and files, and in this command line mode, execute the IPconfig command (if you do not know how to view the network properties in Microsoft OS). The data we need. netmask, gateway, local IP address of the computer (for example 192.169.0.11), port number (usually 3128, 80, 8080, etc.).

Configuring IP Surveillance through a router or a computer, either using the software (a disc with the software is included in the delivery kit), or through a browser, in the address window of which the standard IP of the device is typed. For example, in HikVision cameras. 192.168.0.64 (login. admin, password. 12345). is typed in the browser. On the opened browser control page, enter the Given values ​​of the login and password. After that, the IP addresses of the device (constant, usually for access from the Internet), the mask and the network gateway provided by the provider are entered. Note that installation of IP surveillance cameras may be within a local network, where it is necessary to register a previously prepared route of IP packets on a router or in a computer for broadcasting to the Internet from a LAN. An example of such a command in cmd:

Route ADD.P 10.1.1.1 MASK 255.255.255.255 192.168.0.100 METRIC 1

Here 10.1.1.1. distribution server address (for example, your computer), 192.168.0.100. network camera address. We recommend that you check with Forter’s consultant for more precise commands.

Much easier when independent IP camera setup comes down to replacing its standard address with one adapted to the local network. THOSE. Change the standard 192.168.0.64 to 192.168.1.100.

When setting IP-addressing via software (for HikVision, for example, SADP), the program after initialization on your PC automatically finds all installed cameras of this GoPro manufacturer. After that, you only need to enter the necessary information on the network in the program window. There is also a universal type of software that can recognize cameras from different manufacturers.

When connected cameras through the registrar everything is much simpler. After connecting the device, windows for editing the IP address, netmask, gateway will open in the corresponding register menus. We fill them by analogy with the above values ​​- and you can monitor your object from anywhere in the world!

Installation of IP surveillance cameras: stages and features of installation

The market for control systems, differing both in the complexity of the mechanisms and in the connection methods, is very diverse. All surveillance programs can be divided into two large groups, which differ in functions and methods of execution: analog and digital. The analog group includes cameras that send information through channels with a low transmission rate and quality of information, therefore, digital equIPment is in great demand, as it is more practical and in demand. Among digital control devices, it is worth highlighting IP surveillance cameras that have a fairly high level of quality of transmitted information. over, they are divided into two separate groups according to the method of connection:

  • Wired;
  • Wireless.

What are the features of digital cameras?

IP cameras have a number of positive characteristics, the most significant of which are:

  • Shooting quality;
  • Simultaneous signal transmission with audio and;
  • Updating software automatically;
  • Control the camera remotely with the ability to adjust the position of the device.
READ  Set Up Outdoor Video Camera

Each of the connection options for IP surveillance cameras has its own significant advantages and disadvantages. A wired connection allows you to get a high-quality picture without interruption due to a hard connection, and wireless mechanisms can function in difficult places where there is no way to stretch a line. In wireless devices The only drawback is a signal failure if there are devices nearby, which can create radio interference and thus distort the data transmitted to the central console.

It tells how to set up an IP surveillance system:

System installation steps

Installation of an IP surveillance camera according to a strict institution should be carried out by people who have the appropriate qualifications for this. This need is due to the fact that a person, and not owning the rules for connecting equIPment, can do more harm than good.

It is necessary to install an IP camera according to a pre-developed plan. The entire installation process is divided into the following stages:

  • Preliminary inspection of the equIPment installation site;
  • Direct fastening of the product to the ceiling or wall;
  • Laying a communication line between the device and the central console;
  • Connection of all equIPment into a common circuit;
  • Commissioning and system tuning;
  • Instructing employees on the rules for using the entire complex;
  • Delivery of the object with subsequent maintenance.

Connecting additional control devices

To create a high-quality connection, additional devices are installed for control programs, which allow you to improve the image, even if the mechanisms of the system are at a distance from each other. Before being combined with a monitor, the camera should be connected to the recorder, which will allow compressing information and improve the image quality, and after the changes will transmit the data to the central console.

The picture shows the connection diagram of cameras with digital parameters

The mechanisms with the recorder should be connected using a twisted pair, since this method allows the image to NOT lose quality, despite the range of finding SEPARATE elements. A surveillance camera can be connected using a power cord, which will allow you to transfer information first to the central server, and only after that will send the data to the monitor screen.

It is possible to connect not one camera, but an unlimited number to the general scheme, but you need to remember: by switching on additional cameras, the load on the network increases, and in this case, servicing the entire complex system at the same time will be impossible, which can lead to failures and interference. The quality of work is significantly influenced by the network card, but the speed of the entire complex will depend on its technical capabilities.

Installation of cameras with digital parameters allows you to configure and flash remotely, thanks to their integration into a common local network. The capabilities of IP cameras are constantly increasing due to the development of new chIPs and utilities.

Home surveillance installation. instruction. Connecting cameras and wires in a low-current cabinet.

In any user, the information that IP cameras are much better than analog ones have been firmly in their head lately. This article will consider the princIPle of connecting both IP and analog models.

After all, only a few years ago high definition analog cameras appeared. These are AHD, CVI and TVI formats. In terms of resolution and picture quality, they are practically NOT inferior to the IP format, and at a cost several times cheaper.

They have a switch on the shank, which allows you to transfer them to analog PAL mode.

Before directly mounting the observation in yourself in the house, it is required to depict on paper the locations of the points, the place of laying the cable, etc.

In order to maximize coverage of the entire space around the house, it is necessary to mount at least one camera on each wall. Another one would not hurt to put on the roof in front of the front door.

Here are all the materials you need to install an analog surveillance system:

  • Cable for powering the entire system from a 220V network

It is best to use the brand VVGng-Ls 31.5mm2.

  • Wires for switching in a low-current switchboard. PUGV 1.5mm2

DO NOT confuse with KVN-V. Brand KVN-P. This is a street version, and KVN-V. For laying inside the house. It is not UV protected.

  • 3-core wire PVA cross-section 1.5mm2
  • Analog wall mount cameras. Choose high resolution models.
  • Registrar through which cameras will be connected

Pre-check that the number of inputs on it is equal to or more than the number of cameras.

  • Computer hard drive for storage and recording

The minimum recommended volume. 1tb. You can use both large 3.5 “discs and small 2.5” discs. Small drives are much quieter and have lower heat dissIPation.

For example, the same as used to connect LED strIPs. A standard power supply unit with a cable cross-section of 0.75mm2 is enough for high-quality signal transmission at a distance of no more than 500m.

I select the power of the block according to the same princIPle as in LED strIPs. That is, the total power of all cameras is 30%.

  • If it is necessary that the cameras work even during the period of power outage and the recording is not interrupted for a minute, then you will need a UPS (uninterruptible power supply)
  • BNC-F power supply connectors and BNC male connector

They are needed to connect the cable to the camera itself and connect to the input of the recorder.

  • To protect the contacts and cable connections outdoors, also buy switch boxes with a degree of protection of at least IP52

If you do NOT want all your surveillance to burn out at the first thunderstorm, and do not save on this element of protection.

  • Well, you will also need modular sockets and terminal connectors in the shield.

Recorder, UPS is most conveniently connected through a plug with a socket. Please note that all of these materials must be compatible with each other. Simple IP equIPment will NOT fit analog and vice versa.

Pick up ready-made surveillance kits, or individual components. Cameras, recorders, cables, connectors, plus You can view current here.

The low-current switchboard, where the recorder, power supply, etc. are located, can be located in another room from the common 220V switchboard, sometimes even in the garage or basement.
Therefore, the first step is to bring electricity there.

Wall grooves and We lay the VVGng-Ls 31.5mm2 cable from the 220V switchboard to the low-current cabinet. Power it from a separate modular machine with a rated current of 10A.

In the low-current shields, connect the power cable to the terminals of the second circuit breaker. He will be introductory for this cabinet. And already directly from it you connect modular sockets and a spark gap.

The arresters are connected according to the diagram below. White and brown wire. This is the phase, blue. Zero, yellow-green. Earthing.

Connecting sockets:

The same cabinet contains:

Connect the connectors, and then screw the disk into place with screws.

Next, from the sockets through a regular plug, power the UPS. Most power supplies come without wires with a plug included, so here you have to do it yourself. Use PVA wires and a regular Euro plug.

We mount the plug on one end of the wire, and clean the other and connect it to the unit to the 220V power terminals, designated as L and N.

There is no particular difference in phasing or polarity where to connect zero and phase here. Next, connect the power to the cameras.

If there are not enough 12V output terminals on the unit, it is best to use the terminal blocks. Set them by the number of cameras and label the pins as “V” and “-V”.

Then, using the PGV wires, connect the output terminals 12V and V from the power supply, with the corresponding connectors on the first terminal block.

It is better to use red conductors for a positive GoPro lead, for a negative lead. Black. The rest of the terminals are powered by jumpers.

Now you need to lay the KVK-P cable to each camera, or rather to the place where you planned to place them. It can be laid indoors either in a plastic channel or simply over walls.

On the street, if desired, it can be protected with a corrugation, but not necessarily.

To protect the cable connections from the recorder and the cable from the camera from snow and rain, mount a junction box on the wall and lead the wires into it.

Next, remove the top layer of insulation from the cable, about 8-9 cm, and strIP two power cores. Crimp them with NSHV tIPs.

Insert these wires into the male power connector. There are two connectors “” and “-“. As we have agreed before, the red wire will be a positive contact, black. Minusov.

IP Surveillance Cameras Installation

Then remove the insulation from the coaxial cable.

READ  How To Watch CCTV Cameras Through The Phone

Expose the central core by 3-4mm and mount the BNC-F connector.

Insulate everything from above with a protective cap.

Next, Install the camera itself on the wall. The wires from it run into the junction box where you just installed the BNC-F connectors.

Connecting the connectors together in it and tightly close the lid.

To prevent the ingress of moisture inside, use a box with sealed cable entries on the sides.

All other cameras on the walls of your house are connected in the same way. Each of them will have to pull a separate cable KVK-P.

Now all the observation cables are left to disconnect in the low-current cabinet. First, connect the recorder itself via an uninterruptible power supply.

Then the second ends of the KVK-P cable are cleaned, brought into the cabinet, in the same way as shown above. In this case, the power wires (red with black) connect to the Corresponding terminal blocks “V” and “-V”.

And the end of the coaxial cable, with the installed BNC-F connector, plug into the free slot of the recorder. Where it says In.

Do the same with the remaining cameras.

All you have to do is configure the monitoring by connecting the monitor to the recorder via VGA or HDMI connectors.

If the weak-current cabinet is far from the computer, you can use a laptop for configuration. And after that, with a separate signal output cable to the monitor.

All surveillance software must be included with the cameras. If for some reason it is not there, then you can try universal software, for example from ivideon.

For the installation and installation of IP cameras, in addition to the materials indicated at the beginning of the article, you will need slightly other components:

  • Outdoor PoE IP Cameras

PoE function allows both signal and power to be transmitted over the same cable, through one connector.

It is necessary to connect several cameras from one recorder at once.

  • RJ-45 connectors instead of BNC-F connectors

Check in advance that all components are compatible with each other. Installation of the power section of the low-current board with a circuit breaker, sockets and a surge arrester is carried out in the same way as described above.

The differences are in the connection of the recorder and cables. First, by attaching the PoE switch and NVR power supplies to the din rail. Connect their plugs through the UPS.

Now, in the corrugated pIPe, lay a 4-pair UTP Cat5E cable from the low-current cabinet to the places where the IP cameras are installed.

We mount distribution boxes near the cameras. StrIPping the cable from insulation by 2-3cm.

All pairs must be straightened and aligned in order according to the scheme of the EIA / TIA 568B standard. Colors are counted from left to right.

Types of surveillance cameras

There are various types of cameras in this market segment. They differ from each other in the princIPle of operation, design, technical characteristics.

According to the princIPle of operation, two large groups of devices are distinguished:

  • Analog;
  • Digital.

It is difficult to distinguish them visually, but if you know some of the nuances, then you will never confuse them.

Based on the design features and installation location, the following types are the most popular:

  • Classic or cabinet. They are installed mainly outside, provided they are equIPped with a thermal casing.
  • Dome. Most often installed on the ceiling indoors, but can also be used for outdoor installation.
  • Swivel. Such a user device, located at the control panel, can expand and enlarge the image. The system is convenient when you need to instantly react to a situation.
  • Panoramic. Provides maximum visibility while minimizing blind spots. If necessary, the picture can be split into separate fragments.
  • Mini cameras. Indispensable for covert surveillance.

Street cameras (street. street) are present in both large and small objects. Important characteristics for them are distance from the object, geometry of the view, picture resolution.

Typically, these models are equIPped with IR illumination, a housing that protects against external influences. It is important that it be possible to configure individual parameters automatically.

The device has a viewing angle ranging from 60 to 100⁰. They come in black and white and colored, with or without backlighting. They are compact, have a weak reaction to interference, they can perform shooting both in the daytime and at night.

Dome cameras are used to protect large areas. Their rotation occurs by means of the ptz-mechanism. You can even activate the camera remotely. The picture can not only be returned, but also scaled.

Installation of such a camera is also permissible indoors. The high level of security of this equIPment allows it to be used in difficult weather conditions, in the nuclear and chemical industries.

Box cameras. Their popularity is small. they are not very convenient due to the fact that you need to compose them yourself with a lens and a bracket.

Basically, they are mounted outside, and if inside, then only in such specific places as, for example, a bank cashier. The image is produced by such a camera of high quality, the signal transmission range is quite large, the lens can be changed depending on the distance to the object.

Mini cameras can be powered by a battery, there are both wired and wireless models. They write to a mobile device via a GSM module or to a memory card. They have an increased protection class and good technical characteristics.

Stage # 1. planning and observation schemes

From the very beginning, you need to decide on the installation site, the number of cameras and their task. If you have a private house or summer cottage, then the observation should cover Not only the internal premises, but also the adjacent territory.

In an apartment, cameras are most often installed in order to control the situation during the absence of the owners. It is advisable to have them in living rooms, especially in places where some valuables are stored. It is worth considering installing a camera at the entrance to the apartment.

Having decided on the general questions, they begin to develop the scheme. The locations of the intended laying of wires are chosen so that they do NOT intersect with the existing power line.

It can interfere with the signal if the distance to it is less than one meter. Protect from interference and protection in the form of a metal sleeve, wires are brought into it and grounded.

The next step is to determine the viewing angle. Depending on the goals, it can be configured so that small details are visible or to increase the delight, while sacrificing details.

Next, you should think about where to place the recorder and monitor. Considering confidentiality, access to them should be limited. It’s good if there is a separate closed room or at least a closet.

Self-assembly of the system

If you are going to increase the safety of your home by installing surveillance, you can choose two ways to implement this idea: contact a specialist or start installing surveillance cameras yourself.

The first method is quite costly, and the second is quite feasible if you are familiar with modern technology, and a drill is a familiar tool for you.

# 2. features of analog cameras

An analog camera can be easily recognized by looking at the descrIPtion. If there are three English letters NVL, the camera is analog.

This format is the simplest. there is a camera in the circuit, and two conductors are connected to it. One of them receives power, the second removes the signal. The output picture is not very good quality.

The resolution limit of analog cameras for observation is 720 x 576 pixels, which is several times lower than in modern digital cameras.

Such cameras are called, capable of transmitting an image only over a short distance, simply analog or CVBS. These obsolete standards include VGA, D1, 960H devices.

Installation of surveillance cameras: types of cameras, selection of installation and connection with your own hands

Thinking about purchasing such equIPment, one has to face a lot of questions. Which system is better, what do its characteristics mean, how to choose a suitable model, is it possible to independently install surveillance cameras and connect them? Our detailed review will help you understand all this.

Rules for choosing surveillance cameras

Given the abundance of offers on the market, it is difficult to decide which camera to choose. First of all, you need to decide on the standard by evaluating a number of parameters.

Functionality. If you need a high quality picture, it is important to have intelligent options. motion detection, presence detection, high detail, then you need to purchase an IP camera.

There is also such a nuance: although there are cameras that work autonomously, you cannot include a large number of them in the system. it is optimal. Not more than four. Otherwise, it’s better to use the registrar option.

Resolution. With the transition of analog cameras to HD format, this parameter approached the characteristics of IP cameras. This standard is applicable to any object, but still small details may NOT be considered.

READ  How to place CCTV cameras around the perimeter of the house

The price inclines in favor of their choice, but their functionality is lower and they definitely need a registrar.

Place of installation. If the surveillance system is to be installed outside, the cameras must have the appropriate characteristics. Dome cameras work well for indoor installations without additional protection.

Lens viewing angle and focal length. Wide-angle short-throw lens. a good solution for a cottage, office.

Long focal length lenses and a maximum 45-degree angle of view are a good option for entering a house or for monitoring a distant object when crisp detail is a priority.

There are cameras equIPped with a lens that has a certain focal range, ranging from 2.8 to 12 mm. Such devices are called varifocal.

Based on your needs, you can adjust the viewing angle yourself. The cost of such cameras is much higher than devices equIPped with a lens with a stable focal length.

Some consumers are guided by the megapixel count when buying a camera. This is not entirely true. It is very often difficult to see a big difference in image quality from a 2MP and 8MP IP camera. But the cost differs significantly.

Light sensitivity. This parameter is of great importance when choosing a camera for 24/7 surveillance. This is the minimum illumination threshold at which the camera can function.

The higher this parameter, the clearer the picture obtained at twilight and at night. The latest models almost all have IR illumination, so observation is effective even when it is completely dark.

Given these circumstances, it is imperative to look at what lighting conditions the camera is designed for. Before that, you need to measure this parameter with a luxmeter in the place where the camera is supposed to be mounted. If in the future the device will work around the clock, the photosensitivity should be at least 0.01 lux.

Since the illumination during the day cannot be stable, it is necessary to make sure that the camera has an automatic diaphragm opening control. Such devices are able to maintain a stable luminous flux falling on the matrix.

Cameras with WDR support are of higher quality. Even many economy cameras support this feature, allowing you to display images without deep shadows and overly bright areas.

The only difference is that expensive cameras are equIPped with genuine WDR, while budget cameras are equIPped with analogs.

If the observation should NOT stop either day or night, and the information from the camera should be as detailed as possible, a model with a day-night mode is needed. As soon as night falls, it switches to monochrome mode automatically. The IR filter cannot provide a color picture.

Backlighting. A camera that will work at night must have infrared illumination. The key parameter of IR illumination is range. 10. 20 m is enough for a room, more than 20 m outdoors.

Latest camera models EquIPped with adaptive lighting. Its role is to adjust the power depending on the location of objects located near the camera.

# 3. new standards or HD cameras

By the same princIPle that a simple analog camera is arranged as an HD camera, only this is a more advanced form in which three main formats are combined: TVI, AHD, CVI. This is a breakthrough in analog surveillance.

They can transmit an image with a resolution:

  • 0.4 MP. 722 576;
  • 1 MP. 1280720;
  • 2 MP. 19201080;
  • 3 MP. 20481536;
  • 5 MP. 25601920.

Their quality is comparable to IP cameras. The latest equIPment is capable of transmitting the maximum clarity of the picture captured on site.

The image acquisition mechanism can be briefly described as follows:

  • After passing through the lens, the image is focused on the CCD.
  • Light energy is converted into electrical charge.
  • Conversion of electrical charges into an analog signal occurs.
  • The signal is transmitted through the cable to a pleasant device.

There is no conversion of the electrical signal into binary code, it comes to the recording device unchanged. This is what distinguishes analog cameras from digital ones.

This greatly simplifies the monitoring process, there is no need for processing on a computer.

If you connect an analog camera to a digital converter, it will be possible to receive a signal from several cameras.

When purchasing any camera from the AHD, HD-CVI, HD-TVI category, you should know that they are all incompatible with each other, since they are produced by different companies. When buying a camera of a certain standard, you need to select a recorder for it that supports the same standard.

HD-SDI devices are standardized, so they are compatible with all Recorders. IP cameras are standardized by ON VIF International Interindustry Organization.

This organization is engaged in the standardization of equIPment and IP cameras as well. They also develop specifications for them. Cameras of the same specification are compatible.

Stage # 3. connect the camera correctly

There are only two types of connection: to a power source and to a device that receives information.

To nutrition. Since there is an adapter in each camera, a reduced voltage is supplied through it, its plug is simply connected to the outlet. The plug on the other end is inserted into the chamber. There is a special socket for this on the back of the camera housing.

To the receiving device. For the second connection option, it is necessary to have a wire equIPped with BNC.RG6 connectors. The device has an output for it, and an input on the receiver.

Connecting a wireless camera is even easier. The CD with the program is usually included with the camera. All that remains is to install it on your computer.

Next, connect the router via wi-fi, then the camera itself. It is connected to the network and, using a network cable, connected to the router.

The next step is to configure the network parameters in the program itself. To do this, enter the key and other data and disconnect the network wire. After rebooting, the camera will automatically connect to the router. Now the picture transmitted by the camera will be available.

Cameras can be an element of an intelligent “smart home” system that controls various equIPment in a room. Read more about the device and capabilities of such a complex in this article.

# 1. digital cameras and their characteristics

A digital or IP camera captures a signal in digital form and in the same form transmits it to the consumer via a computer network.

Outwardly, such a camera differs from the others only in the connector. If in analog devices it is BNC. a coaxial radio frequency connector, then the IP camera is equIPped with a twisted pair connector. RJ-45.

Such a surveillance camera is connected to a computer, but here it should be borne in mind that building an entire surveillance system based on a home computer is not worth it.

It is not designed for 24/7 continuous operation and will fail very quickly, especially if several cameras are included in the system. This may be too much of a load for the hard drive.

It is better to immediately purchase a recorder, although many IP cameras are independent devices and have an individual web interface.

There are cameras with a slot for a USB flash drive or with a slot for an SD card, where you can archive recordings. In this case, the need for a registrar disappears.

A great advantage of digital cameras is that while at the other end of the world, you can watch what is happening in your office or at home through a laptop monitor or mobile smartphone.

IP cameras differ from each other in body design.

IP cameras can be connected to cloud storages, with their particIPation, you can create a large-scale surveillance system and include a large number of devices.

Due to the invulnerable authorization system and reliable data encoding, a high degree of security is guaranteed for users.

Also, these devices have great integration potential. It is possible from one device to remotely control surveillance, lighting, fire protection system.

Recording from digital IP has a high resolution, which allows you to see small details, clothes, a person’s face without blur.

Analog cameras do not give such a clear picture, it is difficult to identify what they see. This is explained by the fact that the analog signal is formed using the TVL interleaving system.

In digital cameras, line interleaving is removed using sequential scanning technology. Clearly captures IP camera and fast moving objects.
