Yes, the dash cam continues to work after the car is turned off. This happens because once the dash cam is connected to the car battery, it will continuously draw power from it, even when the vehicle is off.
If the dash cam lacks a low battery protection feature, it will keep draining the battery's power, which could eventually result in a dead battery. When the battery is drained, the car may not start, and you would need to jump-start the vehicle or use an emergency power source to get it running.
The dash cam mainly serves two functions: recording while driving and monitoring when parked. However, its operation is limited by the storage capacity of the memory card and the car's power supply. The dash cam records in a loop, overwriting old footage as needed. Additionally, when the car is turned off, it activates a shock-detection function, which starts recording if the vehicle is impacted, capturing the events as they occur.
The primary purpose of a dash cam is to record videos and take photos that can serve as evidence against staged accidents, provide video footage, and document scenic drives. In the event of a traffic accident, the footage recorded by the dash cam can serve as crucial evidence, significantly improving driving safety and giving the driver peace of mind.
However, one downside of the dash cam is that if it is connected directly to the car battery, it will continue to drain the battery over time, potentially causing the battery to run out of power, which can lead to significant issues for the vehicle. It is recommended that owners install a portable power source for the dash cam, which would allow it to operate around the clock without draining the car battery.
