Problems solved by technology

If you want to extend the recording time, you can choose a time-lag (slow recording) video recorder. In addition to being more expensive, the image frame rate will be reduced and the synchronization will also be affected.
In addition, in order to monitor multiple targets at the same time and reduce the total cost of the system, video switchers or multi-screen splitters are used to enable multiple cameras to share the same monitor and video recorder, among which black and white four-screen splitters are more common, this uses camera + The cost of the "analog-digital-analog" or "analogue-digital-analog-digital" system of four-screen splitter + video monitor / time-lag video recorder is still relatively high
In addition, the inherent disadvantage of using analog video tape as a storage medium is that as the head and tape wear and tear, the playback image quality will become worse and worse, and limited by the sequential recording method of the video tape and the mechanism inertia of the video recorder, the intelligence of these monitoring devices The degree of specialization is low, and it is impossible to make a choice between the monitored object and the recorded content

Abstract

The intelligent monitor system for 4-frame image acquisition device for monitoring images from 4 cameras separately or simultaneously and storing the image information features that 4-frame separator for black-white image and image acquisition card are integrated into one 4-frame image acquisition card, existing A-D-A and A-D-A-D systems are simplified into A / D system, and a compression algorithm integrating in-frame encoding with inter-frame encoding is used.

Description

1. Technical field: [0001] The invention is an innovation of a common video monitoring and monitoring system with a four-picture splitter plus a slow video recorder, and belongs to the technical field of computer application in safety protection, image data collection and compression storage. 2. Background technology: [0002] In order to monitor and record security and prevention targets, industrial cameras, video monitors and ordinary TV recorders are currently used, but the recording time is limited. If you want to extend the recording time, you can choose a time-lag (slow recording) video recorder. In addition to being more expensive, the image frame rate will be reduced and the synchronization will also be affected. In addition, in order to monitor multiple targets at the same time and reduce the total cost of the system, video switchers or multi-screen splitters are used to enable multiple cameras to share the same monitor and video recorder, among which black and whit...
