Does the Dash Cam Still Work When the Car Is Parked?
2 Answers
When the car is parked, the dash cam will usually stop working. However, a small number of dash cams continue to operate even when the car is parked. Whether it works or not depends on which vehicle wire the dash cam is connected to. Some factory-installed dash cams are connected to a constant power source, in which case they do not automatically shut off and can record continuously for 24 hours. If connected to the ACC (Accessory) circuit, the dash cam will automatically turn off when the ignition is switched off, i.e., when the power is cut. A dash cam is a device that records video, audio, and other relevant information while the vehicle is in motion. After installing a dash cam, it can record the entire driving process, including video and audio, providing evidence in case of traffic accidents. For those who enjoy self-driving trips, it can also be used to document the journey through challenging terrains.
Whether the dash cam works after parking mainly depends on the power connection method. Most standard dash cams connected to the cigarette lighter will automatically power off and shut down when the car is turned off, so they stop recording while parked. If connected to a constant power source like the fuse box, the dash cam can continue operating while parked, especially those with parking surveillance features that automatically activate upon detecting vibrations or approaching people to avoid draining the battery. However, this constant-on mode can quickly deplete the car battery, potentially making it difficult to start the engine—I've seen several customers unable to start their cars because of this. It's advisable to check your dash cam's installation to confirm whether it's powered by the cigarette lighter or fuse box. Unless specifically needed, it's best to let it turn off when the engine is shut down.
