Wireless surveillance system solutions
Wireless surveillance system solutions
The wireless network video surveillance system is one of the areas of wireless network technology application。 for the monitoring and control of important regional or remote locations, more and more widely in the field of electric power systems, telecommunications room, factory, urban transport, water systems, district law and order Application。 will be monitored timely transmission of real-time acquisition of video files to the monitoring center, the report of the real-time dynamic monitoring point, to detect problems and handle。
For example, the power system of the substation and unmanned engine room and other facilities of the telecommunications industry will need to install a wireless network video surveillance system. Under normal circumstances, the monitoring point is distributed in a wider range, and the farther the distance with the monitoring center, the use of traditional wired connections, the high cost of laying lines and the construction cycle is long, or because of physical factors is difficult to set up cable encounter obstacles such as rivers and mountains. Wireless network video surveillance solution can be a good solution to the above problem. User wireless network video surveillance solution without the need for laying network cable, can be quickly and easily to the various needs of the local to deploy digital camera equipment, the establishment of a new video surveillance system or extend the existing video surveillance systems, and has a strong flexibility and scalability. Broadband wireless access equipment, multiple monitoring points and the central control center linking, and rapidly build quickly established a wireless link, you can in the shortest possible time. Site monitoring point installed cameras to videotape the real-time video images and high-resolution transmission into electricity pioneer broadband wireless access equipment is sent to the user's security monitoring center, and complete control of the remote monitoring point.
With the development of digital video coding technology and network technology, install network video surveillance systems are rapidly from traditional analog video surveillance system based on cable technology to the development of digital video surveillance system based on IP technology direction, digital monitoring system has been in some areas to replace the existing analog surveillance systems. Compression technology (MPEG4, MPEG2 or MJPEG) uses digital encoding digital video surveillance system based on IP technology and video data for transmission over an IP network, can provide high-quality video surveillance and monitoring range more widely.
Second, Wireless network video surveillance solution with transmission distance, low latency is critical (for video applications), and low cost equipment, can provide efficient and economical solutions for video delivery. Broadband wireless access equipment to provide high network bandwidth 11Mbps/54Mbps different locations on-site video information in real time by means of wireless communication sent to the monitoring center, support H.264 / MPEG-1/2/4 formats such as digital video stable and reliable stream transmission, to ensure stable continuous transmission of video streams, farthest transmission distance can reach more than 50 km, and from the mountains, rivers, bridges, roads, and other complex terrain restrictions.
Third, the characteristics of the wireless network video surveillance system
Alternative to fiber and leased line characteristics of the wireless network video surveillance system, to reduce the cost of network construction, substantial cost savings for the user; short construction cycle, scalability; flexible installation deployment; provide high reliability to ensure that no the intermittent video surveillance; transfer rate, real-time; support RMON. Equipment, low cost, and high cost.
