Can the dashcam record when my car engine is off?

First of all, the camera needs continuous power supply to work.

There are two solutions in this case.

1. Buy hardwire kit & fuse tap and draw power from fuse box directly

Connect the camera by hardwire kit to your fuse box directly, BAT red cable to a constant live port, and ACC to an accessory port, so when the car engine stops, the camera gets a signal from hardwire kit and sends the camera to the parking mode automatically.

2. Use an external battery pack as a power supply

  1. If you use car charger and your cigarette port is constantly live even when the car engine is off, there is a risk of battery drainage; 
  2. If your car battery fuse box has no accessory port (which loses power when the engine is off), there is no way to enter parking mode with hardwire kit.
