As I said I did. So it gained the ability to automatically start and stop recording, depending on the connection of external power. I realize that not everyone is able to do such a modification. But if someone wanted to, I give the program and additional electric circuit diagram. I applied a little extra microcontroller ATTiny45. In standby mode, it gets power from the battery below 1uA. That is over 100 times less than the original camera controller. In order not to interfere with connecting camera to the USB socket, I applied independent connector and automation works only when the power will detect of an additional slot.
Edit: I attached zip, which includes instruction, program and wiring diagram.
