Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] WAN link quality indicators mainly include three parameters: packet loss, delay, and jitter. Among them, packet loss and jitter have the greatest impact on the final display effect of video surveillance streams. For Internet links, operators can often provide certain quality assurance for packet loss, and the main thing that cannot be guaranteed is the jitter parameter. Therefore, if the problem caused by jitter can be solved, the display effect of the video surveillance stream carried on the Internet link will be greatly improved.
[0026] figure 1 The flow chart of the video surveillance method provided by the embodiment of the present invention, such as figure 1 As shown, the specific steps are as follows:
[0027] Step 101: Configure an access control list (ACL, AccessControlList) on the router of the video surveillance ...

The invention discloses a video monitoring method and a router of a video monitoring center. The method comprises configuring the quintuples of all video monitoring flows on the router of the video monitoring center in advance, creating a queue for each video monitoring flow in the cache of the router, defining caching time of each video monitoring flow in advance, when the router of the video monitoring center receives a message and the message is confirmed to be a video monitoring message according to the quintuple of the message, placing the message in the corresponding queue of the cache. If the message is the first message of the queue, the average arriving time interval of the messages of the queue is started to be detected in the predefined caching time of each video monitoring flow, the average arriving time interval is used as a standard messaging time interval of the queue, and the messages are started to be sent according to the standard messaging time interval. The video monitoring method and the router of the video monitoring center improve the quality of video monitoring.
Description
technical field [0001] The invention relates to the technical field of monitoring, in particular to a video monitoring method and a video monitoring center router. Background technique [0002] As the application of video surveillance becomes more and more widespread, many government agencies and enterprises have deployed their own video surveillance networks. For large-scale video surveillance networks, a ) to monitor in real time. However, in many occasions, the distance between the monitoring center and the monitoring point is relatively large, and a WAN link must be deployed. Deploying a WAN dedicated line can often get better monitoring results because the link quality can be guaranteed, but the dedicated line is expensive, and the price of a large-bandwidth dedicated line is unaffordable for many users. The Internet (Internet) link is cheap and has a large bandwidth, but because the quality of the Internet link is not guaranteed, the display effect of the monitoring ...
