Is it necessary to enable motion detection on a dash cam?

[SanEmiliano]

The motion detection feature on a dash cam should be turned on; otherwise, it will affect the normal operation of the parking monitoring function. About dash cam parking monitoring: Dash cams with parking monitoring functionality abandon the traditional method of drawing power from the cigarette lighter or USB port. Instead, they use a step-down cable to directly draw power from the ACC fuse box. After the vehicle is parked and turned off, the dash cam will automatically shut down and enter a low-power sleep mode. However, once it detects a collision or movement of objects in front, it will immediately wake up and record the surrounding footage. Function: Motion detection acts as the 'sensory organ' for the dash cam's parking monitoring. When it detects movement of objects in front, it wakes up the dash cam to record the surrounding footage. Conversely, when no movement is detected and the scene is static, the dash cam will enter sleep mode. This ensures both effective monitoring of the parked vehicle and energy efficiency, preventing the risk of battery drain.
