GSM surveillance cameras: tIPs for choosing, main characteristics and models
The development of mobile communications and the emergence of new, high-tech equIPment made it possible to use the GSM standard in security and fire alarm systems, as well as surveillance. In SEPARATE cases, the use of such systems, there are simply alternatives. The use of GSM surveillance cameras allows a subscriber of a cellular network, depending on the surveillance system, to use the following services:
- Receive automatic SMS and MMS messages;
- View the broadcast from the surveillance camera in real time;
- Connect to the archive;
- Remotely manage the home security system.
Thanks to the installed SIM card, the surveillance system with the introduction of GSM cameras can issue alarm notifications to the mobile devices of several subscribers, including the rapid response team.
Key features and implementation options
Features and Distinctive features of GSM cameras
Structurally, a camera with a GSM module differs from conventional cameras in the way of information transmission. If analog cameras transmit the signal via coaxial cable, and digital cameras transmit the stream via cable twisted pair, A GSM surveillance camera is an analogue of a mobile phone, since it is equIPped with a SIM card slot and has its own number. Monitoring with the introduction of remote control over an object can be organized in 3 options:
- Using cameras with a GSM module
- Connecting conventional cameras to a base unit with GSM
- Application of GSM IP cameras
GSM surveillance for summer cottages
Autonomous GSM surveillance for summer cottages
If it is necessary to implement remote monitoring in the country, followed by viewing what is happening online, sitting at home on your favorite couch at a laptop, a GSM surveillance camera is the best fit for a summer cottage. The only thing that can interfere with the implementation of such a surveillance system is a bad signal of the cellular network, and in this case, you should not even bother with GSM surveillance. But if you really really need it, then you can use special 3G / 4G amplifiers.
In addition, the owner of such a camera will have to pay for Internet access services, because without it, this GSM camera will not be able to fulfill its intended purpose.
The advantage of such cameras is the ability to install them where other types of surveillance are simply physically impossible to implement, or if it is necessary to view what is happening remotely in real mode, when it will be both problematic and more expensive to do this using simple IP cameras or analog surveillance. Such a system is suitable not only for a summer residence, but also for a garage, a country house and other remote objects, the most important thing is a good GSM network signal.
Also, similar GSM cameras are equIPped with an internal storage, which allows them to be used offline. Power can be supplied from the mains, battery, built-in or car battery. You can read about standalone cameras here.
Today, for remote monitoring, the most commonly used IP cameras are connected via 3G mobile Internet. You can read in 4 ways to create Internet surveillance in our article at the link http://nabludaykin.ru/videonablyudenie-cherez-internet.
Connecting cameras to the GSM unit. 1. Cameras with GSM module
The easiest and cheapest way is to use cameras with installed and activated SIM cards. The camera in such a system does not broadcast the data stream, but only sends an SMS or MMS to the specified number. The device sends a photo of the monitored area as a multimedia message upon a phone request or upon triggering a motion sensor. Such a camera can be triggered by an event, request or schedule.
Outdoor 4G Camera
As an example of a camera designed for outdoor surveillance, we will cite a very inexpensive in its segment model of street 4G camera KARKAM KAM-004G.
The device has a built-in 4G (LTE) modem with the ability to instantly alert via SMS or call when movement is detected in the area of the camera sensor. The camera is equIPped with the latest high-performance TI DaVinci DSP DM365, and a modern sensor with a diagonal of 1/4 “- OmniVision OV9712. In addition to the possibility of remote signal transmission via GSM networks, the camera is able to save the stream to the manufacturer’s remote cloud service absolutely free. Also, this unit has a slot for installing memory cards with a capacity of up to 128 MB, so, as mentioned above, the camera has all the characteristics you need to minimize the risk of data loss.
Among other characteristics, we can note the presence of a powerful built-in IR illumination, with a declared range of up to 50 m and an IR filter with an automatic switch. In order to improve the quality of recording, the manufacturer uses a number of innovative technologies in this camera:
- 3DNR. to reduce the amount of noise;
- AWB. automatic selection of white balance;
- WDR. wide dynamic range, is necessary to prevent the occurrence of large light contrast between unequally lit objects;
- BLC. Back Light Compensation, a predecessor feature of WDR, used to prevent the appearance of highlights in the frame. So, for example, when shooting indoors, where there is a large window in the background, the BLC function prevents it from being lit in the recording frame, making the image uniform in brightness.
GSM IP Cameras
Quite expensive, but also the most optimal way of GSM surveillance is using GSM IP cameras. Such a camera is a rather expensive and multifunctional device. These cameras broadcast high-quality images in real time and are equIPped with a built-in solid-state drive, which is designed to store the archive. IP cameras with a GSM module have the following elements in their design:
- Motion Sensor;
- Flash card;
- Infrared illumination.
Outdoor IP camera with GSM module and motion sensor
The GSM IP camera is a multifunctional device that can be the main element of an integrated security system. All modes of operation of cameras can be programmed, therefore, in order to save space on a flash drive, recording can be triggered both by a motion sensor and by a schedule. IP cameras have infrared illumination, which allows recording events at night. The most important requirement for organizing GSM surveillance is the availability of a reliable cellular coverage area, and the cellular operator does not affect the quality and reliability of the system.
When choosing a GSM surveillance camera, you should pay attention to the following parameters:
- Signal to noise ratio;
- Viewing angle;
- Compression format;
- Data transfer rate;
- GSM frequency range.
The first four parameters are common to all types of cameras and determine the quality of the broadcast image and the monitoring area. The rest of the parameters characterize signal compression and data transmission. In modern surveillance systems, image compression using the H.264 or MPEG-4 aLGorithm is used.
You can read more about the choice of surveillance cameras in this article on our website.

Outdoor GSM camera
Cameras used indoors and intended for outdoor use have some design differences, primarily related to operation in various temperature and climatic conditions. An outdoor GSM surveillance camera must meet more stringent requirements than a camera designed for indoor use. The camera is installed in a special thermal casing, which allows the device to work at any temperature. Universal box for GSM outdoor camera is equIPped with an electronic temperature sensor, a heating thermocouple and a miniature fan.
Very often, outdoor cameras are equIPped with additional sensors and can be installed on a rotating turret equIPped with an electric motor to change the monitoring area. A GSM camera with a motion sensor can reliably guard the territory of a private house, a parking lot or an individual parking place. If black-and-white cameras can be used for indoor surveillance, then outdoor cameras that control traffic should be colored. An outdoor GSM surveillance camera with a motion sensor is selected according to the following parameters:
- Viewing angle;
- Infrared illumination distance.
When installing an outdoor camera, the viewing angle is an important criterion. The use of cameras with a wide-angle lens allows you to control a large area with minimal means, but with an increase in the viewing angle, the image detail decreases, and optical distortions occur. Based on this, cameras with both wide-angle and long-focus lenses should be used wisely to monitor outdoor areas.

Camera modes are controlled remotely through the browser of a mobile device.
Powered combo cable
In cases where the camera is powered and the signal is transmitted from one point, it is most convenient to use a combined cable for surveillance systems. It is suitable for both analog and digital devices. This is the same coaxial wire with a resistance of 75 ohms, but in one bundle with the power wires. Thanks to this interlacing, the power of the cameras and signal transmission can be provided without laying additional wires.
Also, in addition to everything, such a cable may contain wires for connecting additional functional elements (for example, a microphone), and for controlling the camera (for example, for controlling a camera rotating device). An example is the KKSEV cable, which, in addition to the coaxial core, has separated wires for power and audio signal.
Among the most commonly used combined surveillance cables are the following brands: KVN-2P, KVK-V-2.
IP Surveillance Cable
IP surveillance cable with RJ-45 connector
To connect digital IP cameras, the same UTP cable is used with crimped RJ-45 connectors at both ends. Its advantage lies in the possibility of laying one common twisted pair line for the whole system of IP surveillance cameras, with the introduction of a switch (switch). The cameras can be powered in three ways:
- Laying a separate power cable for each camera;
- Installation of power supplies in the places where each camera is installed;
- Power supply of cameras using free wires in twisted pair.
The third option is only suitable for those cases when the camera and the switch support PoE (Power of Ethernet) technology, which allows power supply via an Ethernet cable for IP surveillance, in other cases, it is necessary to use Passive PoE injectors, which allow combining signal and power transmission from both sides one cable.
UTP cable for surveillance, or twisted pair
Usually, we resort to using twisted pair in cases where the distance of the intended line from the camera to the signal receiving device is from 300 to 1000 m (the distance of a possible laying of a working observation line using a twisted pair can be up to 3 km). The convenience of using this type of cable for surveillance systems lies in the large number of conductors under one sheath. Thanks to this, it is possible to supply power to the cameras along one line, and transfer the main signals (, audio), and use the remaining wiring to control the camera, as well as to connect an additional camera (there are enough wires in the cable. 8 pcs.).
Depending on the structural features, several types of cable are distinguished. twisted pair. UTP, FTP, STP.
- UTP cable is the simplest, it has no protective shielding, and consists of 8 insulated, twisted in pairs, placed in a common protective sheath. The disadvantages of UTP cables include their low resistance to interference, therefore, in cases of laying communications for surveillance near electrical wiring, and other sources of interference, it is better to use cables with additional protection.
- FTP cable is characterized by the presence of a common foil shielding sheath. Thanks to its presence, this cable can be laid next to electrical cables and other sources of interference. Very important Take care of the safety of the foil screen, And do not exceed the minimum bending radius. no more than 8 outer diameters of the cable. External cable protection can be made of PVC or hard polyethylene.
- STP cable also has a common protective sheath, but not foil, but copper braid. In addition, each conductor in such a cable is solid copper, insulated with polyolefins, and has an individual protective foil shield. External insulation is usually made of fire resistant PVC. The use of this type of cable is necessary in cases of laying over 90 meters in the presence of numerous sources of interference.
When laying STP cable, the shield must be grounded, otherwise it will act like an antenna attracting electromagnetic radiation!
The undoubted advantage of the twisted pair is the large number of conductors, which ensures the connection of all the main functional elements. Also, this cable has a lower cost compared to coaxial.
One source describes the experience of connecting cameras at 700 meters. Colleagues share their observations that UTP collected much less interference in their case compared to shielded FTP, so perhaps UTP surveillance cable is the best choice in such cases. But maybe they just forgot to ground the shield, who knows
When connecting analog cameras using such a cable, transceivers (Baloon) are used as an adapter, which also remove interference from the cable. We invite you to see a very intelligible one in connecting a surveillance camera using a twisted pair.
Coaxial cable for surveillance
Components of a coaxial cable
To connect analog cameras, the most commonly used coaxial cable for surveillance, like the one that connects an external antenna to a TV or receiver. This type of cable is a copper core enclosed in a thick layer of foam dielectric, which is covered on the outside with a shielding protective sheath, which provides good protection against interference and possible signal loss. Most often, domestic brands RK-75-2-13, RK-75-4-12 (RK. radio frequency cable) are used for surveillance, or imported analogues. RG-59, RG-6, RG-11.
When choosing a coaxial cable, it is necessary to take into account such important parameters as the length and location of the installation (indoors or outdoors), and depending on this, purchase a suitable brand of wire.
For example, we lay ZhK-75-2-13 at a line length not exceeding 100 meters, and at longer distances (from 100 to 300 meters) we use the RK-75-3- brands, at distances over 300 meters, usually use UTP (more on that below).
The RG-6 cable differs from its Russian analogs RK-75 primarily by the fact that it has a larger diameter of the central conductor and the sheath. It is also capable of transmitting a slightly larger frequency range than the RK-75, for example, HD-SDI cameras refuse to work with RK, and perfectly transmit a signal via RG-6 with a line length of more than 10 m.
For clarity and more details, we give a table reflecting the dependence of the type of wire on the distance.
Cable selection depending on the distance of the recorder to the camera
When choosing a coaxial cable for surveillance, be sure to make sure that the center conductor is all copper, otherwise the signal will be very weak.
Apart from all the GoPro, coaxial cable differs in other technical criteria such as:
- Flexibility. in cases where the laying of the cable involves bending it in several places, it is necessary to purchase a wire with a stranded central conductor, which will have increased flexibility compared to a monolithic.
- Characteristic impedance. 75 Ohm cables are most often used for monitoring;
- The degree of protection against interference. the presence of shielding shells;
- Insulation diameter;
- Signal attenuation degree;
Pros. The main advantage of this type of cable is its high immunity to interference, affordable price, transmission ability. So does audio signal.
Minuses. The disadvantages of a coaxial cable include the high cost of connectors, easy damage, restrictions on the distance of laying. When using RK brands, it becomes necessary to lay the power wire separately, although this moment cannot always be attributed to disadvantages, since For budget systems, the power supply option for a separate cable will be much cheaper. the savings consist in supplying power to several cameras at the same time, as well as in the high cost of KVN.
Also, when power is supplied separately from the main signal transmission cable, it becomes possible to connect cameras to a network far from the recorder, which is almost impossible to do with a combined cable.
Which cable to choose for observation. the main types and their characteristics
Installing any surveillance system other than wireless is NEVER complete without cable. The cable transfers the signal from the camera to the recorder, provides power, and also connects additional devices, such as a microphone. There are not so many types of cable today, in this material we will tell you about the most common and widely used.
The choice of cable for observation depends on a number of key points. For example, when installing IP surveillance, the wire is usually used twisted pair, that is, a regular network LAN, similar to the one with which we connect a computer to the Internet. The cable for IP surveillance has one interesting feature: with it you can not only connect the camera to the recorder for signal transmission, but also supply power to the camera, as well as connect a sound recording device. We’ll talk about twisted pair later. We will also analyze the 3 main types of cables used for surveillance purposes, but first things first.
Which one is better to choose?
Which cable to choose for a surveillance system?
As a rule, the choice of the appropriate type of cable for surveillance depends on the specific situation, your desires and the cameras selected. In the case of IP cameras, this is almost always the unambiguous use of a UTP cable with RJ-45 connectors, analog surveillance with a small number of cameras can do with ordinary coaxial at distances not exceeding 100-300 meters, but for the possibility of power supply and signal transmission over one cable you must use either a powered surveillance combo cable or a twisted pair cable. With a large number of cameras and longer distances, we would recommend you to use a twisted pair cable. UTP, FTP or STP cable. depending on the distances, place of use (street, indoor premises) and sources of interference.
Differences in the place of laying communications will consist in the fact that for outdoor cameras it is necessary to use a cable with protective external insulation made of solid polyethylene, and for indoor surveillance systems you can take it from ordinary PVC. Also, a cable for outdoor installation can have a steel carrying cable in the structure, which is necessary to strengthen the strength of the cable when laying the cable through the air (KVK-Pt).
In this article, we tried to make out as much as possible the question of how to choose the right cable for observation, talked about the main types and their characteristics, tried to highlight in as much detail as possible the design differences that play the main role in choosing the most suitable cable depending on one or another surveillance systems and your preferences. We wish you good luck and hope that this material remains useful to you.!
Installation of analog cameras
Specialists always focus the attention of novice craftsmen on the nuances that in a professional environment there are certain norms and requirements that must be taken into account when installing equIPment indoors. Many consumers most often give their preference to universal analog cameras, which perfectly cope with the control function. Regardless of the model, such units must contain the following types of connectors:
- RCA, which is popularly referred to as tulIP.
- Red connector, which is needed to connect the power supply.
Separately, it should be noted that RCA connectors can be presented in two colors:
- White color. serves to transmit audio signal.
- Yellow. needed for signal transmission.
To connect the screen to the camera, you must use a high quality RCA cable. The camera output must be connected to the Corresponding TV jack, the same rule applies to the audio output. Each master can select the right or left channel. In classic models, the wire layout is as follows:
- The black wire is always considered a negative.
- Red device cable is a plus.
- Yellow wire provides continuous signal.
The output must be connected to the central core of the coaxial cable. Minus and plus are connected respectively. An RCA connector is screwed to the opposite end of the cable. It should be noted that some modern models are equIPped with a better connector. BNC.
Working princIPle with rotary devices
Contact modules are required to install such devices. As for receivers, not all models can be used. If a camera with two outputs is used, then an additional expander must be selected for it. It is this node that connects to the receiver. The standard scheme provides for the use of one adapter. But each case is individual, as it all depends on the type of expander. All 1-pin models EquIPped with PPC output.
In some cases, when connecting equIPment, there may be problems with the display on the monitor. This problem can be solved using three-channel receivers. In this case, universal adapters with a RK connector can be used.
Essential Observation Materials
Modern manufacturers offer their customers a huge variety of cameras, which have the required durability and affordable price. Most often, a standard module is used to connect such devices. advanced users choose special receivers equIPped with a camera outlet. It is this device that greatly simplifies the process of connecting the system to a personal computer. In order not to be mistaken with the choice, you must take into account the connector for the receiver. The outlet for the camera must be inspected, and possible connection schemes are being studied.
Experienced experts claim that the following materials must be prepared to install an analog system:
- Powerful wires for switching in low-current switchboard devices (PUGV 1.5 mm²).
- Cable for powering the entire laid system (220 V).
- Universal cable KVK-P 20.75 mm². Separately, it should be noted that some confuse this cable with KVN-V, intended for laying inside the house.
- Modern analog cameras with fixing on the wall. The most functional are the models that have high resolution.
- Three-core PVA wire with a cross section of 1.5 mm².
- Multifunctional recorder, which will provide connection of the camera. Before purchasing the selected model, you must make sure that the number of outputs is equal or greater than the number of cameras used.
- Powerful power supply. For example, many craftsmen prefer to use the same models that are used to connect LED strIPs. If the specialist has chosen a cable with a cross section of 0.75 mm², then a standard power supply will be enough for stable and high-quality signal transmission over a distance of 900 meters.
- A hard drive from a computer, which will provide recording and storage. It should be noted that the minimum volume of this device should be 1 TB. As for the size of the Hard Drive, both small (2.5 “) and large (3.5”) models are suitable for use. But, as practice shows, it is compact devices that generate less noise and heat.
- If you need to ensure the smooth operation of the cameras even in the event of a power outage, then you need to purchase a UPS (uninterruptible power supply).
- BNC. F universal power supply connectors and BNC receive connector.
- High quality modular distributor. This equIPment is necessary so that the surveillance system does NOT burn out at the first thunderstorm. As practice shows, it is better not to save on this element of protection.
- To reliably hide all cables and connectors that are on the street, you need to purchase special junction boxes with IP 52 protection system.
- So, without which a high-quality shield cannot work. these are terminal connectors and sockets.
In addition, all devices used must be compatible with each other. So, simple equIPment is NOT compatible with analog systems.
Ways to connect a camera for do-it-yourself surveillance
Every year, universal surveillance systems are gaining in popularity. High-quality continuous control lines are installed in various areas: offices, private houses, apartments and enterprises. The huge advantage of such equIPment is that you can carry out the installation yourself. Basic technical knowledge is required to connect surveillance cameras.
- Essential Observation Materials
- Recommendations for self-installation
- Installation of analog cameras
- Connecting equIPment to a computer
- Working princIPle with rotary devices
- EquIPment setup
Recommendations for self-installation
People more and more often decide to connect surveillance cameras in order to keep order on their territory, at home or at an enterprise. In order for the acquired system to be reliable and durable, you need to know the basic installation rules, as well as some of the secrets of the masters. To properly connect the camera, you need to adhere to the following recommendations:
- A special monitor is always included with the camera, through which users can view everything that happens in the controlled area. The wizard will have to determine the exact place for installing cameras.
- At the next stage, you need to take into account the main installation parameters: the viewing angle and the height of the cameras. It should be noted that the correctness of the image reproduced on the monitor depends on them.
- Now you can proceed with the installation itself. To connect the camera, you need to prepare two cables. coaxial and power. The first wire is required to transmit a clear picture. But the power cable provides power to the device.
- In order for the installed equIPment to receive a high quality signal, it is necessary to calculate the total footage between the camera and the receiver.
Connecting equIPment to a computer
This method of mounting cameras will help the user to save the resulting recording to the hard disk. A huge advantage of the technology is also that a specialist can always program the installed equIPment (for example, the system can turn on independently at a certain period of time). Today, experts are actively using the three most convenient ways to connect the camera to a personal computer. Each option has its own nuances and advantages, which must be taken into account even at the design stage.
The first method is characterized by the fact that the master must equIP the PC with a special capture card, since without it it will be simply impossible to work with cameras. This detail is especially effective when analog cameras are used. The advantage of the board is that it can be used to quickly and efficiently Encode and Process the footage. Depending on the model, the part can be equIPped with from 4 to 16 outputs, which is quite enough for those situations when you need to create your own surveillance system.
The second method is based on the use of a well-known server. With the help of this equIPment, you can digitize the received signals, due to which the cameras used are obtained more functional. Each server is equIPped with a special BNC input, to which modern camera models can be connected. Do not forget about the LAN output, which is intended for connecting a computer. Thanks to this, the owner of the surveillance system has the opportunity to control the entire work process both through a stationary computer and through a laptop.
For the latter option, the specialist will have to use a USB converter, which ensures a reliable connection of cameras to a PC. A huge advantage is that for the stable operation of such a device, a regular USB output is required, which every computer has. The received analog signal can be converted to digital. It should be noted that the picture quality will be quite low. The relative demand for this option is due to the fact that the owner needs minimal financial investments.
When the system is fully installed, you can safely proceed to its configuration. Especially careful should be those craftsmen who are first engaged in the installation of such equIPment. The first step is to configure all cameras. All settings are made through the DVR client program, with which you can control existing devices while sitting at a computer.
When the user is logged in, he needs to open the tab Settings and select a section Add zone. After the performed manIPulations, the program will certainly prompt you to enter a name (digital combinations are allowed). As practice shows, if several cameras are installed at once, then it is better to zoning them all GoProvests, so as not to get confused in the information in the future.
The next step is to connect the registrar to a specific zone. The wizard needs to name it with the right mouse button on an empty field and select one of the proposed options. If the required name of the registrar is already taken, then you need to go to the section Add device. When the entire list of used devices (cameras and registers) is displayed on the screen, you need to open the tab View. These manIPulations will help to display the image from the cameras on the monitor.
Surveillance connection diagram
We bring to your attention a NOT complex scheme for connecting surveillance, cameras to the recorder. Many of our clients, purchasing surveillance systems, are trying to connect the purchased equIPment themselves, and not Having certain skills, this is not an easy task. Our specialist will give brief instructions on how you can independently connect the camera to the recorder and supply power to the camera.
1. Generally, cameras have two connectors, a power connector where 12 V power is supplied and a BNC connector. This is clearly seen in diagram # 1.
2. The recorder also has a BNC connector for receiving a signal from the camera.
3. To connect the camera to the recorder, a coaxial cable is used for monitoring SHVEV for signal transmission over short distances up to 300 m without loss.
4. When choosing a camera power supply, consider the cable length and camera specifications. Let’s say we have four indoor cameras in the kit and the length of the cable from each camera to the recorder is 25 m.In this configuration, a 12V 1.4 A power supply is enough. If our kit includes outdoor cameras, with the same cable footage we we will use the power supply unit BP-4A since the outdoor cameras have heating and infrared illumination and consume more amperes.
