Service Center Television Surveillance System

Introduction

The project "Television Surveillance System" was developed on the basis of contract No. 34SL/2009 of May 26, 2009.

The project was developed in accordance with the current state norms and rules for the design of construction facilities:

• Decree of the Government of the Russian Federation of February 16, 2008 No. 87 "On the composition of sections of design documentation and requirements to their content";

• P 78.36.00299 "Selection and use of television video monitoring systems";

• RD 78.36.00299 "Technical means of facilities safety systems. Symbols and schematic graphic elements of systems ";

• SNiP 3.05.0685 "Electrical devices";

• GOST R 515582000 "Television security systems. General technical requirements and test methods ";

• PUE Edition 7 "Electrical Installation Rules."

The following were used as input data:

• site plans;

• engineering survey materials;

• technical documentation for the used STN equipment.

Purpose of the system

The television surveillance system (STN) is designed for round-the-clock remote surveillance using video cameras on the monitor screen and recording the situation on the site, ensuring that the security service is able to assess the situation in real time at the site, reduce the response time to an extreme situation and ensure that appropriate measures are taken as soon as possible to protect against encroachments.

STN also provides:

• archiving of video information for further analysis of events;

• programming of operation modes;

• switching of image from cameras to monitor in manual mode;

• viewing of previously recorded sequence of images in automatic mode;

• notification of video signal loss using iconographic information;

• digital recording of images on hard magnetic disks in long-term recording mode and in real time;

• simultaneous recording of the current image and reproduction of previously recorded images;

• intelligent motion detection;

• filtering of natural interference;

• storage of established parameters in non-volatile memory in case of power supply voltage loss;

• delimiting the operator's authority according to their authority through the password system; display of the current time monitor, date, TV camera number.

Key Solutions

The television surveillance system (STN) is implemented on the basis of the Intellect hardware and software complex (AIC). The system is designed to protect any scale of complexity of the object: large, medium and small.

The system has a powerful functionally distributed architecture:

• Unlimited number of video servers and surveillance cameras;

• Remote monitoring and administration

• The ability to install any number of workplaces;

• Building a complete centralized video surveillance system.

The system allows to monitor several zones of motion detection on each camera with individual settings of detection parameters and mask, allows to control the system by events from individual zones.

The most important parameter of the video surveillance system is the quality of the displayed and stored video information. Achieving the maximum result in the system is ensured by using the following solutions:

• the use of a unique video compression algorithm MotionWavelet, the main advantage of which is precisely the high quality of the compressed image with a significantly smaller frame size compared to other algorithms;

• use of a unique deinterlaying algorithm (elimination of the "comb" effect) for the maximum resolution frame, which does not introduce distortion at the boundaries of objects and does not reduce the real resolution of the frame;

• application of software image enhancement.

The main requirement for a video surveillance system is the reliability, stability and uninterrupted operation of the system 7 days a week, 24 hours a day, 365 days a year. To meet these requirements, special solutions are implemented in both the hardware and software parts of all subsystems of the complex:

• system serviceability check;

• Prevent possible errors or failures

• correct recovery of all subsystems in case of failure.

• The system has unique network capabilities:

• Video archives of any video server can be transferred permanently or on schedule in real time to dedicated servers - archivers for long-term storage.

• Each client can access both the archive of the video server and the archives of the dedicated servers - archivers.

• Video streams can be distributed in the system using the Video Gateway module, that is, each next client receiving a video stream from a particular server will not increase the load on the communication channel with this server. The client can receive a video stream from a server in another network segment via a video gateway.

The following are selected for operation as part of STN:

• Smartec STC3080/3 ULTIMATE body video cameras with day/night mode with variofocal lenses that allow you to observe in color mode with good lighting and black and white mode in low light conditions. For all external surveillance cameras, thermocouples STH1230DPSU1 designed for operation in a wide temperature range are provided;

• color video cameras in the MDC7220V hemisphere housing equipped with a variofocal lens;

• CCTV IR sensor housing color cameras.

Operating Principles

STN is implemented on the basis of the "Intelligence" hardware and software complex (AIC) and is its subsystem. Functionally, it consists of two video servers for collecting and processing information over 20 channels. The images are output using four 19 "monitors, two for each video server, and the servers are controlled using the keyboard and mouse manipulator put on the operator's desktop with the help of ALSO extensions. On the first and second of the four installed 19-inch monitors, an image is displayed from all street video cameras of the object, and on the third and fourth from all internal cameras.

The signal from the video cameras to the receiving equipment is transmitted using symmetrical amplifiers located in the immediate vicinity of the video cameras (in thermowells or in switching boxes) via a twisted-pair cable (CCI cable, FTP), which allows transmitting the video signal over a longer distance than through a coaxial cable and provides increased noise immunity. The signal from the video camera on the gearbox (TK10) is transmitted via coaxial cable RK75332 directly to the input of the video server.

The dessimetered signal from the multi-channel video signal receivers is transmitted via a twisted pair to a DVR, where it is digitized, compressed and recorded on a hard disk.
