Which power source should a dash cam be connected to?

[Stevie]

A dash cam should be connected to either the cigarette lighter socket or the ACC power source in the fuse box. Here is more information about dash cam power sources: 1. Dash cams generally have built-in power sources and external power interfaces. The built-in power source is usually a lithium battery, while the external power source is typically supplied through the cigarette lighter. The capacity of the built-in battery is usually very small, providing power for about an hour, whereas the external power supply is more convenient and can last for a longer duration. 2. The built-in lithium battery must be avoided from strong light exposure. Installing the dash cam on the rearview mirror can help avoid strong light exposure. 3. ACC power supply is more complicated, with a more complex installation process that may affect the car's aesthetics, but this method provides power for a longer time.
