Security monitoring Intelligent analysis of system technology
1、 Access control system
The access control system is used to manage the important channels of intelligent residence. The door control system can control the entry and exit of personnel, as well as the behavior of personnel in buildings and sensitive areas. Control devices, such as card readers, fingerprint readers, password keyboards, etc., shall be installed at the door of the building, elevators, etc. If residents want to enter, they must have a card or input the correct password, or press the special finger to get through. The access control system can effectively manage the opening and closing of doors, ensure the free access of authorized personnel, and restrict Access by authorized personnel Security monitoring system 。
2、 Closed circuit monitoring system
As one of the monitoring and information means for the security status of the work area, the closed-circuit monitoring system, in combination with the internal intercom system and the public address system, echoes each other from afar, which can reduce the work intensity of managers and improve the management quality and efficiency. As a powerful auxiliary means of modern security, the closed-circuit monitoring system transmits the video images or danger signals of each site to the main control center and the sub management room. The management personnel on duty can objectively monitor each area without going to the site in person, uniformly mobilize the discovered situation, guide the evacuation, and save a lot of patrol personnel, A small number of people can avoid many human factors and ensure the implementation of the scheme properly handled in a short time.
3、 Intrusion alarm system
Intrusion alarm system generally consists of detector and alarm controller , linkage controller, analog display screen, searchlight, etc. The general intrusion alarm system uses linear detectors. Linear detectors mostly use dual/four active infrared detectors to form an illegal crossing alarm system. The system adopts fuzzy control technology to effectively avoid the impact of small animals, sundries, snowstorms, etc. on the detection and alarm, and at the same time ensure the real-time alarm of large objects and people's illegal crossing behavior. When the detector detects the intrusion signal, it will alarm to the property alarm reception center of the community. The alarm reception center linkage controller will turn on the searchlight in the relevant area, send out the alarm siren, start the video recorder, simulate the electronic screen to dynamically display the alarm area, and the alarm reception center monitoring computer will pop up the electronic map.
4、 Electronic patrol system
The patrol system is a means for managers to check whether the patrollers arrive at the designated place at the designated time according to the patrol route. The patrol system helps managers understand the performance of patrol personnel, and managers can change patrol routes at any time through software to meet the needs of different occasions. The patrol system is divided into wired and wireless:
The wireless patrol system consists of information buttons, patrol hand-held recorder, downloader, computer and its management software. Information buttons are installed on the site, such as near the entrance of each residential building, garage, main roads, etc; Patrol hand-held recorder shall be carried by patrol personnel on duty; The downloader is a part that connects the handheld recorder and the computer for information exchange. It is located in the computer room. The wireless patrol system is simple to install, does not need a special computer, and is very convenient for system expansion, modification and management Security monitoring System.
The wired patrol system is that the patrol personnel send a signal back to the management computer at the specified time and place on the specified patrol route to indicate that it is normal. If the signal is not sent to the management computer within the specified time, or the signal does not appear in the specified order, the system will consider it abnormal. In this way, problems or dangers of patrol personnel will be quickly detected.
5、 Visual intercom system
The traditional analog visual intercom system is composed of management center, visual outdoor host, visual indoor extension power supply and other parts. It can realize three-way communication, building intercom, image monitoring, integrated alarm, door lock opening, alarm memory, and integrated management of the center. The system adopts 485 wiring transmission mode. According to different requirements, it can be externally connected with door magnetic, infrared, smoke detector, gas probe, computer center, workstation and "110" alarm center to implement intelligent community management.
6、 Perimeter protection system
The perimeter guard fence alarm system mainly monitors the surrounding conditions of the building to prevent illegal intrusion. It is a line of defense for the anti-theft alarm system and also a very important line of defense.
The perimeter protection sensor can detect the intruder as soon as he enters the defense zone, and give an alarm before he approaches the protected person and property. An effective outdoor safety system can reduce the risk of theft, damage and personal injury as the return of equipment investment security monitoring system.
7、 Intelligent residential security system
The family anti-theft alarm system is mainly composed of the security center management host, family alarm, various sensors and transmission lines. The entry point is mainly doors and windows. Sensors are deployed to important places and areas of families, so that owners can live in a safer and more comfortable environment.
