Does the Dash Cam Continue Recording When the Car is Turned Off?
1 Answers
Normally, a dash cam cannot record when the car is turned off. If the dash cam has a parking monitoring function, it can continue recording after the vehicle is turned off, but the recording time is limited. This is because the dash cam's power is supplied by the car, so it can only operate when the car is running. Some dash cams have built-in batteries, but the battery capacity is too small to support prolonged operation. Connecting the dash cam directly to the car battery can cause prolonged discharge, which may affect the battery's lifespan. A dash cam is a device that records video and audio information during vehicle operation. After installation, it can document the entire driving process, providing crucial evidence in case of traffic accidents. Parking monitoring functions in dash cams come in two types: one is continuous recording, and the other activates short-term recording only when the vehicle detects vibration. However, there are currently no dash cams capable of continuous long-term recording after the car is turned off. For parking monitoring to work, the dash cam must either have an embedded rechargeable battery or be connected to the fuse box (ACC power). After the vehicle is turned off, it automatically enters parking surveillance mode, where sensors continuously monitor the vehicle's status. If any abnormal activity or vibration is detected, the dash cam automatically records and stores the footage separately. Compared to constant power connection, dash cams with parking monitoring connected via the fuse box (ACC) are more energy-efficient and reduce harm to the car battery. However, if the vehicle remains unused for several days, the battery may still drain, making it difficult to start the car.
