The abbreviation GSM stands for Global System for Mobile communication. The system allows transmitting information according to mobile communication standards using 2G, 3G or 4G in various frequency ranges.

Principle of operation
Often, such communication channels are selected for work through which it is impossible to correctly transmit large-volume streaming video without loss, so broadcasting is done in frames or in small clips.
The GSM camera itself for video surveillance is only one part of a whole range of equipment necessary for security. A GSM camera can be purchased separately or as part of a ready-to-use kit.
The standalone camera has a GSM module for data transfer. To do this, use the SIM card of any operator, which is necessary for the security system to work. Data will be transferred from the device to the tablet or smartphone.
Camera activation occurs when the alarm sensor is triggered. Then a series of shots or a clip is recorded. After that, the files are instantly sent to the user's phone or tablet in the form of SMS or MMS, and are also duplicated by e-mail.
Where and how is used
Outdoor GSM Camera
There are no special restrictions for GSM cameras. To work, you only need the presence of cellular communications. Coverage will directly affect the quality of data transfer. The video surveillance system is located in private houses, apartments, industrial facilities, where there is no Internet access.
Often, stand-alone GSM cameras can be found in the forest, where devices equipped with motion and night sensors are installed to monitor animals. In such remote places there is no Internet connection, but cellular communication can work. The device is activated when there is a moving object, in this case, an animal. After that, the camera takes a few shots or a short clip.
Similarly, the device can work in a country house or in a private house, where there is no Internet access. Activation will include if there are moving objects. Devices can be either stand-alone or powered by some source. Properly placed GSM cameras will allow you to create a high-quality security system for the home, where there is no stable Internet connection via Wi-Fi or 4G.
Types of cameras
GSM internal camera
GSM-cameras are divided into groups depending on various characteristics:
- According to the specifics of the place of use:
- outdoor - designed to work in an open space, therefore, equipped with special devices (anti-vandal protection, a visor, a leather casing and so on, the set of add-ons will depend on the manufacturer and the selected model);
- internal - for rooms, therefore, do not have special devices for protection.
- By functionality:
- MMS - data transmission is possible only using MMS, frames or short recording in low quality are sent to the phone, you cannot watch video from the camera online;
- GPRS - the functionality of such a camera is already higher, because the device allows you to record and transmit video, as well as get acquainted with the situation online.
- By type of viewing angle:
- fixed, with a wide-angle telescopic viewing angle, the focus can be variable or fixed;
- PTZ or PTZ cameras have a focus adjustment function and rotary mechanisms, such devices use a wide-angle lens, models have up to 360 degrees of shooting;
- panoramic - devices that are capable of simultaneously shooting 360-degree video without turns, are most often installed stationary, although some models can tilt.
In the market of GSM-cameras you can find models that can be equipped with many sensors without problems, and not just standard ones, sensitive to noise, smoke or movements. In some cases, several sensors are connected to the cameras at once, so that the cameras give complete information about the situation. Summer residents can independently determine which GSM video camera and with what sensors they need to give.
Installation methods
GSM Camera Installed
To install a workable surveillance system, it is necessary to comprehensively approach the issue of installation and connection of devices. Unlike standard cameras in GSM, data transfer is due to the SIM card, and not via coaxial wire. Each SIM card has its own identification number, which allows the user to receive remote access in one of three types:
- the use of GSM cameras;
- connection of digital devices to the block of the GSM module;
- use of IP cameras with a GSM module.
The easiest way is to purchase and install GSM cameras. All that is needed is to install the devices themselves and insert SIM cards into them for data transfer. Since the camera does not transmit streaming video, the user will have to adjust the intervals of the devices. They can be fixed (for example, every hour) or depending on the operation of motion sensors, smoke or noise.
And connecting to the GSM module is a bit more complicated. In this case, the data will be transferred by this device. The main difficulty is connecting other types of cameras to this module for correct data transfer.
Advantages and disadvantages of GSM cameras
The main advantage of the devices is that they transmit data using the mobile coverage area. Wi-Fi or high-quality 4G Internet is not available anywhere in the world. In order for the camcorder to give GSM to begin to fulfill its purpose, just insert the SIM card into the device.
But the disadvantage results in an advantage - you need a constant uninterrupted connection to the network. It is also easy to intercept devices or create electromagnetic interference. In this case, the signal will completely disappear or the data will be transmitted with a delay.
