Component Editing
video Security monitoring The system is generally composed of four main parts: front-end, transmission, control and display record. The front end includes one or more video camera And the supporting lens, pan tilt, protective cover, decoding driver, etc; The transmission part includes cables and/or optical cables, as well as possible wired/wireless signal modulation and demodulation equipment, etc; The control part mainly includes video switcher and pan tilt lens controller , operating keyboard, type control communication interface, power supply and its supporting console, monitor cabinet, etc; Display and recording equipment mainly includes monitors, video recorders, multi screen splitters, etc.
System Type Edit
Video security monitoring system There are basically two types of monitoring systems. One is a monitoring system that works independently locally and does not support network transmission and remote network monitoring. This video security monitoring system is usually suitable for internal applications. Both the monitoring end and the monitored end need to be fixed. This type of video security monitoring system is common in the early days. The other can work independently locally or in collaboration with the network. It is characterized by supporting remote network monitoring. As long as there are passwords and networked computers, security monitoring can be carried out anytime and anywhere, represented by the network.
Composition mode editing
According to the purpose of use, protection scope, information transmission mode, control mode, etc., the video security monitoring system can have multiple composition modes.
1. Simple correspondence mode: simple correspondence between monitor and camera.
2. Timing switching mode: at least one channel of video output can be used for timing switching of video images.
3. Matrix switching mode: any front-end video input signal can be switched to any output monitor through any control keyboard, and various timing switching programs can be prepared.
4. Virtual switching/switching mode of digital video network: digital encoding function is added to analog camera, which is called network camera. The front end of digital video can also be other digital cameras. The digital switching transmission network can be Ethernet, DDN, SDH and other transmission networks. Digital encoding equipment can use DVR or video with recording function The server Digital video processing, control and recording measures can be implemented in any link of front-end, transmission and display.
Control part of video security monitoring system
The control part mainly includes the video switcher, PTZ lens controller, operating keyboard, various control communication interfaces, power supply and supporting console, monitor cabinet, system host, etc.
