Will connecting a dash cam to ACC power drain the battery?

[AndersonDella]

Connecting a dash cam to ACC power will not drain the battery. Whether it will cause battery drain depends on the following situations: Dash cam connected to constant power: If connected to constant power, it means the dash cam continues to draw electricity even when the car is parked. In this case, if the dash cam does not have low-voltage protection for the battery, prolonged parking will drain the car's battery. Dash cam connected to ACC: Power is only supplied when the vehicle's ignition is turned on, which will not cause battery drain, but parking monitoring cannot be achieved. Smart voltage reducer cable: To reduce the possibility of the dash cam draining the battery, a voltage reducer cable continuously monitors the battery voltage. By setting a voltage threshold in a mobile app, the dash cam will stop working when the voltage drops below the set value, thereby protecting the battery voltage.
