Can the Dash Cam Work When the Car is Turned Off?
1 Answers
Dash cams can work when the car is turned off, provided that the device has a parking monitoring (motion detection) function. The parking monitoring feature requires the dash cam to have a built-in battery or to be connected to the ACC fuse for power supply. After the vehicle is turned off, the dash cam automatically enters parking monitoring mode, where its sensors continuously monitor the vehicle's condition. If any abnormality or vibration is detected, it will automatically record the monitoring video and save it separately. Compared to constant power connection, dash cams with parking monitoring connected to the ACC fuse are more energy-efficient and have less impact on the car battery. However, if the vehicle is left unused for several consecutive days, this may still lead to battery drain and difficulty starting the car.
