<p>The present invention relates to the field of video monitors. Disclosed are a high-reliability, extensible video storage and search method and a system thereof, so as to increase system reliability, avoid information islands, reduce management complexity, and implement capacity extension. In the present invention, Based on a hardware system formed of at least two interconnected master devices, at least one salve device, and at least one camera. The master device provides a mapping table and a database. One master device is a working master device, and the other master device is a hot standby master device. The method comprises the following steps: a working master device finding a salve device corresponding to a camera in a mapping table thereof; the working master device triggering the camera to record a video, and triggering a corresponding salve device to store the video data; and the working master device and a hot standby master device synchronously updating databases thereof.</p> |
