Method and system for video monitoring and centralized recording in GPRS network environment

Abstract

The present invention discloses a method and system for video monitoring and centralized recording in a GPRS network environment. The method includes: after obtaining an alarm, a front end monitoring apparatus records locally, and reports recording file information to a central storage server after the recording is completed; after receiving the recording file information, the central storage server updates a file download list according to the recording file information, and returns data download request information to the front end monitoring apparatus; and the front end monitoring apparatus sends corresponding recording file data to the central storage server according to the data download request. According to the method and the system, storing and recording are first performed by the front end monitoring apparatus and then data is uploaded to the central storage server. Further, the method and the system support a transfer resuming function, achieve centralized storage of recording files, and prevent incapability, caused by a network problem, of effectively performing recording in the video monitoring.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video monitoring centralized video recording method and system under a GPRS network environment. Background technique [0002] Such as figure 1 As shown, in the existing wireless network video monitoring system networking, the network elements it includes are mainly: a front-end camera and an encoder, and the encoder encodes the video information collected by the camera, and then adopts GPRS ( General Packet Radio Service (GPRS) mode is connected to the fixed network, and the server and the client are in the fixed network environment. [0003] In the GPRS network environment, due to the limited bandwidth and unstable network, the video surveillance system cannot centrally store video, and because the video stored at the front end is easily limited by the size of the memory card, it cannot store long-term video. To solve this problem, in the prior art, the video files...

Problems solved by technology

[0003] In the GPRS network environment, due to the limited bandwidth and unstable network, the video surveillance system cannot centrally store videos, and because the storage of videos at the front end is easily limited by the size of the memory card, it cannot store long-term videos

In view of this problem, in the prior art, the video files are often copied by improving the GPRS wireless network or regularly going to the front-end monitoring point by the management personnel. However, if these two methods are used for centralized storage of the video files, the cost is relatively high
