What functions should a complete security system have?

(1) Video monitoring adopts various cameras, switch control hosts, multi-screen displays, analog or digital recording devices and lighting devices to effectively monitor the inside and outside, including key departments, important facilities and public offices.

Activity place.

(2) Image Verification When an alarm occurs, the monitor displays the scene of the alarm, thus intuitively confirming the report.

Alarm, and make effective alarm processing.

(3) When the card reader reads the card or uses the biometric characteristics of the human body as a voucher, the image recognition system can call out the stored employee photos for confirmation, and identify the visitors through image scanning and comparison.

2. Detection and alarm function

(1) The sensors configured for internal defense detection include dual recognition movement detector, passive infrared detector, glass breakage detector, sound detector, optical fiber loop, door contact, door lock status indication, etc.

(2) Detection technologies such as pickup cable, optical fiber, inertial sensor, underground cable, capacitance sensor, microwave and active infrared detector are selected for perimeter prevention detection, and security detection is carried out for fences, high walls and unmanned areas.

(3) Emergency monitoring personnel can call the police by pressing the emergency alarm button or entering a specific serial password in the card reader. Through the linkage control of internal communication system and closed-circuit television system, when an alarm occurs, it will automatically make a sound or make a phone call, and display and record the alarm image.

(4) The graphic recognition monitoring center will automatically display the information points of alarm status on the plan, so that the personnel on duty can get the alarm information in time and deal with the alarm quickly, effectively and correctly.

3. Control function

(1) For the control of the image system, the most important thing is the image switching display control and operation control. The control system structure is as follows:

A. The central control equipment directly controls the camera front ends one by one.

B, centralized control is carried out by a central control device through a decoder.

C. New distributed control

(2) Identification control

A. Access control: Using IC card, induction card, Wigan card and magnetic card can effectively control the entrance and exit. In addition to the card, you can also use passwords and human biometrics, and access events can be automatically logged in and stored.

B. Vehicle access control: The parking lot monitoring and charging management system is adopted, and vehicles are controlled to enter and leave the parking lot through entrance and exit fences and anti-collision baffles.

C access control of special elevators: the card reader installed outside the elevator is only used by people with specific identities, while the equipment installed inside the elevator is only used by people authorized to reach the designated floor.

(3) Linkage control in response to alarm This linkage logic control can be set to close key entrances and exits such as warehouses, control rooms, main doors and passages in case of emergency, providing complete safety control functions.

4. Automatic auxiliary function

(1) Internal communication The internal communication system provides the communication function between the central control room and employees. These functions include holding meetings, maintaining communication with all workstations, selecting answering auxiliary machines, anti-jamming substations and digital recording. It integrates wireless communication, telephone and closed-circuit television system, and can better perform the identification function.

(2) Two-way wireless communication Two-way wireless communication provides flexible and practical communication functions for the central control room and employees under dynamic conditions, and the wireless communication machine is also equipped with anti-attack alarm equipment.

(3) The switching design of wired broadcast matrix provides flexibility in playing music, transmitting instructions and broadcasting emergency information in a certain area.

(4) Telephone dialing provides the function of transmitting information to the outside world in an emergency. When the mobile phone system is redundant, it is integrated with the main console of the internal communication system to provide more effective operation functions.

(5) Patrol management patrol points can be door locks or card readers. The patrol management system is combined with the closed-circuit television system to check whether the patrolman is in place and ensure safety.

(6) The employee attendance card reader can be conveniently used for employee attendance at work, and the system can also be networked with the salary management system.

(7) Resources * * * sharing and facilities reservation The integrated security management system is networked with the building management system and office automation management system, which can provide comprehensive control of import and export, lighting and registration and scheduling, and effectively enjoy public facilities such as conference rooms.
