Video Surveillance System with Two Channels and Information Transmission

CCTV with recognition is widely used today. They are designed to provide information about the current state of a protected object (process) by collecting, processing, archiving, storing, displaying and analyzing this information. Modern video surveillance systems seek the outside world through the exchange of data via the Internet and allow not so much to observe the object and record the information received, but lately can process it with the use of image recognition algorithms and automatically affect the object management systems.

The purpose of this work is to analyze the features of construction and operation of video surveillance systems, to consider various options for data transfer and the implementation of face recognition. Offer advanced CCTV options, such as additional face identification and emergency communications features. 

New CCTV systems are being built using IP cameras and related software. Smartphones and tablets, laptops, traditional computers and cloud technologies are also widely used as video viewing devices. Video surveillance is an important part of the security system, where IP cameras, recognition features and information transmission modules are now widely used in security systems.

It is advisable to use an IP camera when there is constant Wi-Fi, which allows the information to be transmitted continuously. Surveillance cameras and human identification are important in that they can collect and store individuals' faces. 

The diversity of people's faces is enormous, which is why the system has a low probability of recognition. The requirements for the design and construction of such systems are incredibly high.

Considering all the advantages and disadvantages of different types of data transmission modules, it follows that GSM is the best option for transmitting notifications, as its range is almost limitless. And the video stream can be transmitted both via GSM and via Wi-Fi.

As a result of the analysis of modern autonomous CCTV systems, a variant of the system with additional functions is proposed. The system has two communication channels for better communication and identification. 

This system can be used in offices, establishments, and in ordinary homes. The proposed security system is available in facilities where an admission system is required.

The system works as follows. For example, the room has a CCTV system and access is available to only three people. Their faces are already recorded in memory. When a person approaches the camera, the system identifies it and aligns it with the already stored information about the persons it has access to. If there is no match, a message is sent via the GSM module about the penetration of the object and a link to the IP address of the embedded server from which the video is broadcast from the premises.
