[0004] The advantage of multi-device linkage with a master-slave relationship is that the control method is simple. However, as the cost of video surveillance equipment decreases and the penetration rate of intelligent analysis functions increases, the disadvantages of multi-device linkage with a simple master-slave relationship are also highlighted.
The multi-device linkage of the master-slave relationship mainly depends on the calculation and processing of the master video surveillance device. Every action from the video surveillance device to find the target to the precise positioning needs to be carried out after the master video surveillance device indicates. The determination of the tracking target and the entire tracking The analysis of the movement of the tracking target du

specific Embodiment
[0083] In a specific embodiment, the priority of camera 1 is higher than that of camera 2. When camera 1 informs camera 2 to perform the first zooming, camera 2 will engage in intelligent analysis. If camera 1 changes the suspicious target at this time, camera 2 needs to exit the current task and turn to analyze the latest suspicious target provided by camera 1 The coordinates of the current physical location.

Abstract
The invention discloses a video monitoring method and a system. According to the method and the system, the operation speed and the response speed of the video monitoring system can be increased, the target tracking performance is optimized, and the timeliness of target tracking is improved. The method includes: a second video monitoring device receives coordinates of the current physical positions of a to-be-tracked object sent by a connected first video monitoring device at regular intervals of the preset duration, the visual angle of the first video monitoring device is fixed, the visual angle of the second video monitoring device is adjustable, and the first video monitoring device and the second video monitoring device perform coordinate calibration of the physical positions by employing the same coordinate calibration method; and the second video monitoring device determines the to-be-tracked object from two or more moving objects according to the received coordinates of the more than one current physical positions, and locks and tracks the to-be-tracked object.
