Embodiment Construction

[0011] Such as figure 1 As shown, a digital video surveillance system includes an image signal collector, a video signal processor, a video signal A / D converter, a video signal codec processor, a dynamic data signal processor, a terminal display, a file memory, an audio signal The collector, the audio signal codec processor and the loudspeaker, the video signal processor includes the image signal processor and the dynamic signal separator, the image signal collector collects the image signal of the target scene, enters the image signal processor for processing, and then sends it to the video signal A The / D converter performs A / D conversion of the video signal, and the A / D conversion of the video signal by the video signal A / D converter is then sent to the video signal codec processor for codec and then sent to the terminal display for display. The audio signal of the target scene collected by the collector is sent to the audio signal A / D converter for audio signal A / D convers...

Abstract

The invention relates to a digital video recording monitoring system. A dynamic signal separator which can judge whether a target scene is abnormal or not and form a start-stop dynamic signal and a dynamic data signal processor which can automatically notify a file storage device for starting and stopping the stored dynamic data according to the start-stop dynamic signal are increasedly arranged in the prior digital video recording monitoring system, thereby allowing the digital video recording monitoring system to automatically judge whether video information is stored or not according to the situation of whether the target scene is abnormal or not, the video recording can be carried out only when people or other moving objects appear in the target scene, and the video recording is not carried out in normal situation, thereby greatly reducing the video recording time and solving the technical problem that the prior digital video recording monitoring system needs the whole-course video recording and further causes the consumption of a lot of storage hardware resources.

Description

technical field [0001] The invention relates to a digital video surveillance system. Background technique [0002] Existing digital video surveillance system includes image signal collector, video signal processor, video signal A / D converter, video signal codec processor, terminal display and file memory, video signal processor includes image signal processor; The image signal of the target scene collected by the signal collector is input to the image signal processor for processing and then sent to the video signal A / D converter for video signal A / D conversion. After the video signal A / D conversion is performed by the video signal A / D converter It is then sent to the video signal codec processor for codec and then sent to the terminal display for display. The file memory stores the video signal in the whole process. Because the video signal is stored in the whole process, it will consume a lot of storage hardware resources. Contents of the invention [0003] The inventio...
