Hello,
The G-Sensor on the camera is for detecting incidents when the car is moving. If you're looking for the camera to activate when the car is off, then Parking Mode is the feature that you require.
The Series 2 Cameras have an internal lithium ion battery for emergency uses, such as the loss of power during an incident. This will allow the camera to continue recording to the end of the clip before switching off.
This internal battery has around 10-15 minutes of battery life.
However with the Rear Camera added, the battery life is drastically reduced due to the additional power draw. This is usually 1-3 minutes if fully charged.
If you intend on using Parking Mode on your camera, then we'd instead recommend using a Hard Wire Kit, not the Cigarette Lighter Cable. The Hard Wire Kit will allow the camera to draw nominal current from the car's battery, preventing the cam's battery from being drained. The Hard Wire Kit has an in-built voltage cut off which protects the car's battery from being drained below 11.2V. We'd recommend using a Permanent Live fuse.
For Parking Mode, if the camera is completely still for five minutes (the car is parked), then the camera will 'hibernate' in Parking Mode.
If your car is bumped and the G Force sensor registers movement then the dash cam will automatically turn on, record for 30 seconds and then shut back down again. If you are unlucky enough to be hit twice in a row then the dash cam would automatically record again and capture both events.
