The composition of intrusion alarm system is generally composed of perimeter protection, building internal (external) area/space protection and physical target protection alone or in combination. The front-end equipment of the system is various types of intrusion detectors (sensors), and the transmission mode can be wired or wireless, and wired transmission can also be dedicated line transmission and telephone line transmission. The terminal display, control and equipment communication of the system can use alarm controller or alarm center console. When designing the system, the configuration of intrusion detector should make its detection range have enough coverage, and various detectors with different detection principles should be considered.
Video security monitoring system
Video surveillance &; Control system (VSCS) refers to an electronic system or network, which uses video technology to detect and monitor fortified areas, and displays and records on-site images in real time.
The front-end equipment of the system is various types of cameras (or video alarms) and their ancillary equipment, and the transmission mode can be coaxial cable transmission or optical fiber transmission; The terminal equipment of the system is display, recording, control and communication equipment (including multimedia technology equipment), and generally an independent video console or monitoring and alarm console is adopted. Access control system (ACS) is an electronic system or network, which uses user-defined identifier recognition or/and pattern recognition technology to identify access targets and control the opening and closing of access actuators.
Access control system generally consists of three parts: access control object (person or thing) identification device, access control information processing, control, communication device and access control actuator. The entrance and exit control system should have preventive measures to prevent more than one card from entering and leaving, and should have a password system to prevent similar equipment from illegally copying valid identity documents, and the password system should be authorized to modify. Electronic patrol system: Electronic patrol system refers to the electronic system that manages and controls the patrol route, mode and process of security patrol personnel.
Parking management system: Parking management system refers to an electronic system or network that automatically logs in, monitors and manages vehicles entering and leaving the parking lot.
Explosion-proof safety inspection system: Leak-proof and explosion-proof safety inspection system refers to the electronic equipment system or network that checks whether relevant personnel, luggage and goods carry explosives, weapons and/or other contraband.
Anti-theft and anti-robbery alarm system for vehicles and moving targets
Alarm communication command system
Television monitoring system: Television monitoring system monitors and records the scene images in real time by means of image monitoring. The monitoring system allows security personnel to intuitively grasp the scene situation and analyze it through video playback. The TV monitoring system is an important part of the applied TV system and also an important part of the security system. At present, TV monitoring system has been organically combined with anti-theft alarm system to form a more reliable monitoring system.
Other subsystems (such as buildings and structures with special functional requirements, or special parts and positions in them) need to design safety technical prevention systems with special functions, such as special high-security entity protection systems, explosion-proof and safety inspection systems, and safety information broadcasting systems. )
