Abstract

The invention relates to a method for videoing or searching video of a digital video recorder. On the digital video recorder (DVR)connected with a plurality of monitoring-use cameras, a plurality of monitoring-use cameras with coherence are divided into a Linked Camera Group and at the same time monitoring videos photographed by any monitoring-use cameras are recorded; or under a condition that the recorded monitoring video is searched, the monitoring video photographed by a plurality of the monitoring-use cameras is recorded according to the group of the monitoring-use cameras or the recorded monitoring video is searched, thus effectively recording and searching a plurality of monitoring videos required by the user which have the coherence with the monitoring-use cameras simultaneously; therefore, the method for videoing or searching the video of the digital video recorder can improve convenience for the user and monitoring performance.

Description

technical field [0001] The present invention relates to an image recording or retrieval method of a digital video recorder, in particular to a digital video recorder (DVR: Digital Video Recorder) connected to a plurality of surveillance cameras, in order to more effectively record or retrieve a digital image of surveillance images Video recording or retrieval method of video recorder. Background technique [0002] Generally speaking, surveillance cameras are set on the ceiling of a specific place to shoot the corresponding area, such as figure 1 As shown, multiple surveillance cameras 100 1 ~100 n On the camera, the subjects in the corresponding areas are photographed respectively, and then output to the digital video recorder DVR200 installed at a long distance. [0003] In addition, on the above-mentioned digital video recorder 200, the monitoring video captured by the above-mentioned monitoring camera is output through the display (Monitor) 300 into a plurality of spli...
