Does the Dash Cam Record When the Car is Off?

Without resetting the dash cam, it cannot record after being turned off. When the dash cam is powered off, it is equivalent to losing power, and the device cannot operate without a power supply. When the vehicle is turned off and power is cut, the dash cam will use its built-in lithium battery to continue recording, but the recording time is relatively short. Here are some details about dash cams: 1. A dash cam is a device that records video, audio, and other related information during vehicle travel. After installation, it can capture the entire driving process in video and audio, providing evidence for determining liability in traffic accidents. 2. Based on vehicle type and functionality, dash cams can be categorized as: high-definition dash cams, mini dash cams, night vision dash cams, wide-angle dash cams, dual-lens dash cams, multifunctional all-in-one devices, and glasses-style multifunctional dash cams. 3. In terms of resolution, dash cams are available in four types: 300,000 pixels, 1.3 million pixels, 2 million pixels, and 5 million pixels. Some models claim 12 million pixels, but this refers to static photo resolution, not video pixel value.
I've spent quite some time researching dash cams and found that whether they continue recording after the car is turned off depends on the specific model and settings. Generally, dash cams relying on cigarette lighter power will stop recording once power is cut, but higher-end models come with built-in batteries or parking surveillance modes. For instance, they can automatically wake up to record for several seconds when detecting collisions or motion – a quite useful anti-theft feature. I recommend checking the manual to see if this mode is supported and setting the motion detection sensitivity appropriately, otherwise it may drain the car battery quickly, especially in older vehicles. For 24/7 recording, it's best to hardwire the dash cam to a constant power fuse box port, which is more reliable but requires attention to power consumption control.
