However, please note that the backup camera can only be powered when the main device receives external power supply.
  • The images captured by the backup camera are stored automatically in the memory card of the main device. When the storage limit is reached for the memory card, the oldest images will be overwritten by the latest ones and deleted in turn cyclically.
  • When the backup camera is correctly installed and the connection is in normal state, the screen of the main device will display the backup image when the car is shifted to reverse gear, and will return to the previous interface when the car is shifted out of reverse gear.
