Car DVR camera units usually operate via the vehicle electrical system, converting the 13.8V to a 5V USB connector. Car DVR camera can be plugged in via the cigarette lighter socket, or may be hardwired directly into the electrical system, freeing up the power outlet for other uses.
In order to store files and properly format the media card when power is turned off, Car DVR camera use either a Lithium Polymer (LiPo) battery or a capacitor. While both provide power for a very short period of time, they have very different operating capabilities and limitations. LiPo batteries have an estimated life of 2-3 years or roughly 300-500 cycles. Over time, the material inside the battery will start to degrade resulting in out-gassing. This can be observed in a swollen or puffy looking battery case. When a LiPo battery reaches this point, the battery is no longer able to hold a charge. The result is a camera that may randomly turn on or off, or register format errors if it can't shut down correctly when power is turned off since it can only function when using the power from the vehicle. Capacitors can also store a temporary charge and will last much longer. They are also more resistant to higher operating temperatures, but are more expensive and require additional hardware or software support. Generally the LiPo batteries are found in less expensive dashcams and capacitors are used in more expensive Car DVR camera.
