During the recording process, the video collection unit dynamically adjusts the focus, angle and exposure of the camera according to the real-time data provided by the vibration sensing unit and the sound sensing unit to ensure the quality and clarity of the recorded video. If the abnormal event continues to occur or the scope expands, the video collection unit will automatically expand the recording scope, increase the number of cameras or adjust the camera layout to comprehensively record the abnormal event.

If no abnormality occurs, the video collection unit is turned off and waits for the next trigger. When a suspicious target is identified, the recognition unit determines whether the target is moving. If the target is moving, a signal is sent to the switching view unit to request cooperation in target tracking. At the same time, the recognition unit continuously monitors the video data to detect whether the vehicle status is abnormal (such as scratches, dents, etc.). If an abnormality is detected, the abnormal position is marked, and the replacement unit is prepared to activate the replacement unit for picture replacement (to prevent the initial photo taken when the engine is turned off from being used and compared after a second abnormal event occurs). According to the target position of the abnormal event, the recognition unit sends specific tracking instructions to the switching view unit, including the target position, tracking speed, etc. Switching viewing angle unit: when the recognition unit sends a tracking instruction, the switching viewing angle unit receives the instruction and determines to switch to the appropriate viewing angle according to information such as the target position and tracking speed; the switching viewing angle unit sends an instruction to the video collection unit to adjust the focus, angle and exposure of the camera to capture the details of the suspicious target; when the suspicious target moves to the edge of the screen recorded by a recorder in the video collection unit, the switching viewing angle unit predicts the next screen area it will enter according to the target's moving direction, and switches to this viewing angle in advance for monitoring; when the suspicious target leaves all shooting ranges, the switching viewing angle unit sends an instruction to the video collection unit to start all recorders to record the vehicle status for a certain period of time (such as 5-10 seconds) to ensure that nothing is missed; after recording is completed, turn off this function and the video collection unit to save power.
