Do all dashcams record when the car is off?

Whether a dash cam continues to work after the vehicle is turned off depends on its functions and power supply method. Dash cams with parking monitoring function can still record after the vehicle is turned off, usually through a built-in battery or connection to constant power (such as taking power from the fuse ACC). The former keeps recording until storage is full or the battery is depleted, while the latter only initiates short-term recording when motion is detected. Single-camera or dual-camera dash cams have a limited field of view (covering only the front or front and rear), while 360-degree panoramic dash cams can provide comprehensive monitoring. Prolonged use of parking monitoring may drain the car battery. It is best to select models with high-capacity built-in batteries and park the vehicle in monitored areas to enhance security. Additionally, the time-lapse recording function can compress video duration, enabling round-the-clock surveillance while reducing storage consumption.
