Features of high-altitude observation video surveillance

What are the characteristics of high-altitude observation security monitoring? The structure is clear and simple: because the monitoring host has completed many functions of the video matrix, screen splitter and other equipment in the imitation system through the Xiangshi network video centralized monitoring system management software, and completed the video recording function through the computer hard disk, the system structure is greatly simplified and integrated. high degree. The management application is cumbersome: Since the digital monitoring system is based on computer and network equipment, most of the system control and management functions are completed by the computer, and there is no need to imitate many complicated equipment in the system, which reduces the management work intensity of the operation and maintenance personnel. Powerful operation functions: a variety of display forms; multi-screen intelligent switching patrol; a variety of early warning forms; real-time, timing, alarm trigger, start and stop at any time and other recording methods; picture capture and printing; intelligent fast video playback query and so on. Monitoring and viewing is cumbersome: due to the characteristics of the network-based centralized monitoring of all-digital network video, there is no need to increase equipment investment. The remote or local monitoring center on the network can monitor, record or arbitrarily play back one or more monitoring scene images in real time. Authorized networking The computer can also perform the monitoring function, preventing the inconvenience and absence of monitoring and management due to the distance of the astronomical position. High security capability: image mask technology to avoid illegal tampering with video materials; any authorized computer on the network can perform video backup to effectively avoid malicious damage; network failure and disconnect cache function to effectively protect video data; video interruption Host alarm function; authorized hierarchical management function; powerful log management function. Unlimited and seamless expansion ability: The increase of surveillance cameras is mainly due to the increase of remote monitoring points at the front end, and the monitoring front end is marked by IP addresses. Adding devices only means the expansion of IP addresses. A simple structure can form a huge multi-level monitoring network. .
