The Wi-Fi will not operate if the camera is connected to your PC USB. This is due to the active data lines in the USB connection. To resolve this please power the camera from your vehicle accessory socket with the power cable supplied, or via one of our hardwire kits. If testing indoors, away from the vehicle, we recommend using a mains charger USB as this will not have active data lines and the camera will behave correctly the same as being in use in the vehicle.
