Video surveillance method based on p2p technology

Abstract

The invention relates to a video monitoring technology based on an IP network and discloses a video monitoring method based on a P2P technology. The P2P technology is integrated into platform forwarding and under a condition that stable input of excellent audio and video streams is ensured, a platform forwarding pressure is reduced. In the video monitoring method based on the P2P technology, a camera accesses through a terminal access layer and registers to a platform and a client accesses the platform through a client access layer so as to obtain and select the information of a registered camera; after receiving a related notification signaling, the camera transmits video data to the terminal access layer and transmits the video data to a platform scheduling layer; the platform scheduling layer carries out corresponding scheduling and selects a media distribution and video recording layer to receive the video data and distribute the video data to a corresponding client; and a node tracking module records and tracks an online state of the client and the use condition of the camera. The video monitoring method based on the P2P technology is suitable for remote video monitoring.

Description

technical field [0001] The invention relates to video monitoring technology based on IP network, in particular to a video monitoring method based on P2P technology. Background technique [0002] The purpose of P2P (peer-to-peer network connection) technology is to distribute, utilize and share resources. It is opposed to the dominant C / S system in the network. The status of each node in the P2P mode is equal in the network. The role of the client, each node can not only provide services, but also enjoy the services of other nodes. P2P technology has now developed into a very mature technology and is widely used in VOIP, streaming media and other fields. [0003] There are two main ways to implement network video surveillance: [0004] One is the direct connection method, that is, the network camera is directly connected to the client through the network. The advantage of this connection method is that it is simple and convenient, and does not require the support of the ser...

Problems solved by technology

[0004] One is the direct connection method, that is, the network camera is directly connected to the client through the network. The advantage of this connection method is that it is simple and convenient, and does not require the support of the server. The disadvantage is that it is greatly affected by the network. If the network quality is not good, the client The quality of the obtained video is relatively poor, and there are often picture delays and out-of-sync audio and video phenomena; with the increase in the number of users accessing, the pressure of multi-channel distribution of the network camera is increased, causing the camera to hang up and the connection to be closed, which makes the user Can not get a good experience, this direct connection method is only suitable for small-scale network video surveillance systems

[0005] Another way is the platform forwarding method, that is, after the video stream of the network camera is connected to the platform, it is forwarded to multiple users through the platform. The advantage is that the pressure of concurrent video streams is directly transferred to the platform. Through the number of platform servers or hardware configuration performance, Solve the pressure of large-scale user video concurrency; by building a platform on an unreachable network, it can provide stable input and output of media streams. The disadvantage is that a large number of servers need to be deployed to support the entire platform. This method is suitable for large-scale city-level video surveillance systems.
