I've been reading about Low Bitrate Recording (LBR) mode for Parking Mode on the N4. I understand that it's generally described as 720p @ 15fps. However, I have a few specific questions about how it behaves:
- Per the firmware update notes where it was added, it's stated that it will go into LBR if it doesn't detect movement for 5 minutes. However, how does it detect that movement? Is it based on the G-Sensor/accelerometer, image based motion detection or something else?
- As an extension of the first question, how does it know when to exit parking mode and return to normal driving mode? I.e. when I start driving, how do I know if/when it goes back to full resolution and fps recording?
EDIT: The release notes for VTN40L.V9 indicate that it "Improve the sensitivity of parking vibration gsensor to avoid the possibility of entering the parking mode during driving." - that would suggest that it uses the G-Sensor/accelerometer?
- Does it record on all 3 cameras in Low Bitrate Recording mode? I'll try and experiment to answer this one myself if it's not known. My particular usecase is vandalism detection so the interior camera is important to me (I appreciate others are less concerned about this).
- If it detects a collision or significant movement, will it change out of LBR back into full resolution recording? For instance, if it detects a collision with the car, will it record the best images available from that point forward. This may be desirable as it would produce the LBR recording before the collision (e.g. of the car or person approaching) and then a full resolution video which may more clearly identify them after the collision occured.
- As an extension of the fourth question, even if it doesn't change out of LBR, does the collision sensor automatic lock still function?
