What are the characteristics of video surveillance system?

1. The digitization of video surveillance must first change the information flow (including video, audio, control, etc. ) From analog state to digital state in the system, this will completely break the structure of "the classic CCTV system is centered on camera imaging technology" and fundamentally change the way and structure of video surveillance system from information collection, data processing, transmission and system control. The digitalization, coding compression and open protocol of information flow make the intelligent network video surveillance system seamlessly connected with the subsystems in the security system, and realize management and control on a unified operating platform, which is the significance of system integration.

2. Based on this system structure, the video surveillance network will change from an integrated system to a distributed system. The distributed system adopts multi-layer hierarchical structure and has multi-task, multi-user and distributed operating system with micro-kernel technology, which realizes the rapid response of preemptive task scheduling algorithm. The hardware and software of the distributed video surveillance system are designed in a standardized, modular and systematic way. The equipment configuration of video surveillance system has the functions of strong universality, good openness, flexible system configuration, perfect control function, convenient data processing, friendly man-machine interface, simplified system installation, debugging and maintenance, system safety, fault tolerance and reliability.

3. The networking of video surveillance has broken the geographical and quantitative boundaries of deployment control area and equipment expansion to a certain extent. System networking will make the whole network system enjoy hardware and software resources as well as tasks and loads, which is an important concept of system integration. Webcam.
