update log:
1, power indicator will be light when external power input;
2, Rotate Image 180degree problem will occur on HDR 1080P mode. working on this with Ambarella engineers.
3, hold OK button to take photo, this can only be done on 1080P or 720P mode now. working on this with Ambarella engineers.
4, added "0806" before firmware version, for easier firmware identification when users need an upgrade.
5, add "AV-OUT" setting between "PARKING GUARD" and "GREEN INDICATOR", as a switch of AV-OUT. (AV-OUT will consume power, so it is recommended to switch it off if you don't need to output AV signal.) (Please reboot the camera to make AV-OUT take effect.)
