Can the Dash Cam Continue Recording After the Car is Turned Off?
2 Answers
Whether the dash cam can continue recording after the car is turned off is explained as follows: If the dash cam is equipped with a parking monitoring function, it can continue recording after the vehicle is turned off, but the recording time is not long since the dash cam cannot be charged after the vehicle is turned off. Additional information: 1. Classification of dash cams: The parking monitoring function of dash cams can be divided into two types, one is continuous recording, and the other is short-term recording that only starts when the vehicle is shaken. However, there is no dash cam that can continuously and persistently record after the vehicle is turned off. 2. Working time of dash cams: Dash cams operate using the car's power during the day. When the vehicle is turned off, the dash cam will stop working. Although many dash cams have built-in batteries, some batteries can only last for four or five hours at most, while others can only maintain power for about half an hour. Therefore, generally, dash cams cannot continue recording for a long time after the car is parked and turned off.
After using a dash cam for five years, I've learned that whether it works after the engine is off depends on the power supply method. Like my old car that used the cigarette lighter socket - it would cut power immediately when the key was removed, completely missing any activity in the engine bay. Now I've switched to fuse box power supply, specifically asking the technician to connect it to a constant power fuse, so it keeps recording even when locked. But battery capacity needs attention - last time I didn't drive for ten days on a business trip and returned to a dead battery that couldn't start the car. For long-term parking surveillance, it's best to install a voltage-regulated power cable with protection function that automatically cuts off when battery voltage drops below 11.6V for peace of mind.
