BlackVue dashcams offer Battery Protection Settings to prevent your car battery from being drained when the camera is in Parking Mode. These settings are available under Settings > Firmware settings > Recording Mode> Parking Mode Recording.

1. Voltage Cut-Off

This defines the minimum voltage threshold at which the dashcam will automatically shut off to prevent excessive battery drain.

•  12V system (most passenger cars)
  Range: 11.8V to 12.5V
• 24V system (trucks, buses)
  Range: 22.8V to 24.0V

Tip

• Higher voltage cut-off = more conservative protection.
• If unsure, 12.0V (for 12V cars) and 24.0V (for 24V vehicles) are safe starting points.

2. Timer Cut-Off

• Sets how long the dashcam will remain in Parking Mode before automatically turning off, regardless of battery voltage.

• Options typically range from 1 hour up to 48 hrs.

• Helpful if you only want to monitor for a fixed period while parked.

3. Priority Setting

• When both Voltage Cut-Off and Timer Cut-Off are enabled, the dashcam will shut down based on whichever condition is met first.

• Choose Voltage Priority if protecting the car battery is more important.

Note

• Battery Protection Settings are only applicable to 3-wire dashcam models (ACC + BATT + GND) and only when using the Hardwiring Cable or OBD-II Power Cable.

• Use BlackVue’s Ultra batteries accessories for worry-free parking protection.
