Video monitoring system and video detection method thereof
By introducing processing and control circuits into the video surveillance system and comparing the video signal with the data check code value, the problem of abnormal surveillance images is solved, ensuring the accuracy and security of the images. Especially when used in vehicles, the reflective mirror display area avoids the influence of erroneous images.

AI Technical Summary
Existing monitoring devices cannot effectively detect the accuracy of monitoring images, which may lead to abnormal phenomena such as broken images, discolored images, or snow-like images, thus failing to meet security requirements.
By introducing processing, driving, and control circuits into the video surveillance system, the input and output video signals are compared using data check code values to ensure that the display device shows the correct image. The processing circuit calculates a first data check code value and compares it with a second data check code value calculated by the driving circuit. The control circuit shuts down the display device when an inconsistency is detected.
Ensuring the accuracy of surveillance images and avoiding the display of erroneous images improves system security, especially when used in vehicles, as the reflective mirror display area prevents erroneous images from affecting safe operation.
