2. Q:　Can I use the rear camera and use it to record interior of the car?

A：The rear camera is always recording to a second stream, so you could mount it to wherever you want.

3. Q：Does the motion detection work when the car is off? If so, how does this work if there is no battery?

A： You can use hardwire kit to connect Dashcam to the car's constant power(not ACC connection). The Dashcam will get the power from car battery in motion detection mode and stop working when car battery voltage is below 11.2V. It's not recommended to enable motion detection in cold weather because the car may not be able to start.

4. Q: What data is recorded by the optional gps? Position, speed, time, heading, etc?

A: Yes, the gps tracks position, speed in km, time, and heading. without the gps you can set up time manually but won't know position, heading, or speed.
