What are the benefits of remote video?

To realize remote network monitoring, the first problem to be solved is 1, whether there is a network; 2. Bandwidth; 3. I hope to transmit the images of several cameras at the same time; 4. Whether the picture requires real-time monitoring; 5. Quality requirements of transmitted images; 6. Whether to look at the pictures of several branches far apart on the same screen at the same time; 7, whether cascade, such as district street level, municipal level, provincial level.

Only by designing according to the actual situation can we get the most ideal solution.

Hard disk video recorders have solved the problem of long-time video recording, completely replacing traditional video recorders, and some of them have the function of remote network transmission; Both the video server and the webcam are completely dependent on the network, and the network is not allowed to pause a little, otherwise nothing can be seen or recorded.

In actual demand, there are many scenes that do not need video recording and real-time monitoring. When the number of cameras is only a few, choosing a webcam can achieve the lowest investment.

Large-scale remote video surveillance transmission systems often use leased lines (or directly use broadband access, such as ADSL, LAN, VPN, etc. ), and the bandwidth of WAN built by leased lines is often lower than that of LAN (100M). When multiple users of LAN access real-time video streams through WAN, the bandwidth of WAN is a bottleneck.

Five video service request tasks are sent to the streaming media server in the local area network, and the streaming media server obtains the video stream through the wide area network and forwards it to five requesting users at the same time, which can save five times the bandwidth resources. The streaming media server can respond to the requests of multiple users at the same time. When the monitoring centers at all levels are equipped with streaming media servers, the streaming media at the higher level can be forwarded through the streaming media servers at the lower level.

In the demand of large-scale WAN centralized monitoring, the streaming media server can also be placed in the telecom room, and then a special line is pulled from the telecom room to the monitoring center.

Network remote monitoring, unlimited transmission distance, convenient monitoring; The monitor screen switching is simple and quick; Image image access is simple and easy; One device replaces the traditional picture segmentation processor, controller and video recorder, and the comprehensive cost is greatly reduced; In particular, some hard disk video recorders have the function of WEB server, so that management can know the production situation of the factory at any time in different places, which is convenient for management.

Because network interconnection needs to know the IP of the monitored device, the remote terminal can find the monitoring device and connect to the mirror. Network remote monitoring is a new application based on IP, and the IP of each branch point is mostly dynamic IP (a new IP address will be redistributed after leaving the network, and the cost of fixed IP is more expensive), so it is very important to support the connection of dynamic IP in software and application.

Guangzhou Xinkang Technology has a mature solution to large-scale remote centralized monitoring.
