Safety includes seven major industries:
1. Monitoring
Guard against theft
3. Building intercom system
4. Background music and broadcasting
5. Explosion prevention and safety inspection
6. Parking lot management
Step 7 patrol
Take anti-theft as an example: a system must have an alarm host, a front-end probe and a transmission device (or cable).
However, according to different customer requirements and purposes, a large number of devices can be expanded: door magnets, buttons, alarm signals, alarm centers, telephone lines and so on. The front-end probe can be divided into active infrared, passive infrared, smoke sensor, gas sensor, vibration probe, temperature sensor, glass breaking and so on.

Security system integration: English security system integration refers to the integrated design, installation and debugging, customized interface development and application support of related equipment and software by using integrated wiring technology, communication technology, network interconnection technology, multimedia application technology, security technology and network security technology for the purpose of building a security management platform within an organization. The integrated security system subsystem includes access control system, building intercom system, monitoring system, anti-theft alarm, all-in-one card, parking management, fire control system, multimedia display system and remote conference system. Security system integration can be used as an independent system integration project, and can also be included in the intelligent building system integration as a subsystem. (The new definition of system integration put forward by Qianjia.com on March 3rd, 2008)
Summary of several security integrated systems
Now there are two kinds of security integrated systems widely used in engineering. One is represented by the graphic management system AD5500 "Legend of the King" and the security system NTK22O0 "Skynet" introduced by AD/NTK company. The former comprehensively controls CCTV, access control, internal communication and alarm in a single workstation, while the latter integrates network communication and system integration to realize access control, visual intercom, alarm and telephone line transmission of AD switches and brands. The other type takes ADEMCO security integration system introduced by ADEMCO Group as an example, which is mainly the linkage integration of alarm, access control and CCTV system. Because of the open communication protocol and microcomputer design characteristics of Javelin CCTV system, CCTV system is very easy to integrate with other systems.
Video capture system:
The video acquisition system is mainly composed of cameras at various observation points, which mainly completes the acquisition of video image signals. It consists of eight existing high-performance color digital cameras. It mainly realizes the video acquisition of each acquisition point.
Brief introduction to the protection of each part of image monitoring: (with monitoring point plan)
Each cashier in the supermarket has 1 fixed monitoring points, * * *: 5 points; There are two monitoring points on the edge of the jewelry counter and makeup cabinet. Set 1 fixed monitoring point on the billing cabinet; Set 1 monitoring point at the entrance of Zheng Da; Arrange 7 monitoring points in the supermarket sales area; The whole project has 16 monitoring points.
Pan/tilt lens control system;
The lens control system of PTZ is mainly composed of PTZ and controller. It is used to change the observation position of the remote control camera in the monitoring center and enlarge and reduce the image of the observation point.
Signal transmission system:
In this system, the signal transmission system mainly includes three parts: power signal transmission, video signal transmission and control signal transmission line.
Video processing system:
The video processing system mainly completes digital processing of video signals, display of image signals, storage of image signals and remote transmission of image signals. The system adopts hard disk video recording and remote transmission system to realize the display, video recording, playback and remote browsing of all acquisition points.
System function description:
1. The most advanced digital compression technology (MPEG-4) is adopted to realize the display, storage, playback and remote transmission of images through computer processing.
2. Each display, storage and playback can reach 6.25 frames per second.
3. The display resolution can reach 768*576, and the storage and playback resolution can reach 384*288.
4. The observation value of each observation point can be stored on the hard disk.
5. Historical storage records can be played back during storage.
6. Historical records are all time-stamped.
7. The system is highly integrated, even on computers ... >>
Question 2: What are the security equipment? Video monitoring mainly includes: camera, cloud platform, hard disk video recorder, monitor, video cable, power cable, etc. , as well as optical cables and optical terminals. It is needed when the distance is far away. Infrared monitoring mainly includes: infrared external probe (transmitting and receiving), monitoring host and signal (power supply) line, etc. Actually, I'm not familiar with surveillance cameras. I've only been in this business for three or four months, so it's more appropriate to install a surveillance camera with a computer. Which equipment is more reasonable to install depends on the actual scene that should be used. For example, the brands and products on Huaqiang Security Network are quite complete, and security monitoring and some peripheral products are also involved. There should be some measurement and control equipment I haven't mentioned yet, so I can go and have a look from time to time.
