The camera boots rare, I can not rely on the fact that it starts up correctly at startup. Very often it is after the sounding of the start-up tone just hang and can be freed from it not even a reset. She obviously has no G-sensor, although it is a menu item available, but the activation of the option does not lead to behavioral change of the camera. There are also some other menu items available, which lead nowhere.
The software was obviously adjusted by using the hot needle on the hardware.
If the camera is running time, it provides a very useful picture, but by the nonexistent reliability it is unsuitable for the intended use as a car camera.
