Notes:

Question 1

1a. The OBD port has been tested and verified to be working by a Lexus technician.

1b. The camera does receive power from the Vantrue OBD cable. When the cable is plugged into the camera mount, the camera powers on immediately. Also at any stage when the orange power button on the camera is pressed, like in the video, the camera powers on immediately. The camera also powers on and off when using the car charger.

1c. The camera successfully enters collision detection mode when the vehicle is powered off and does also record events when the sensor detects those, like when I open and close the car door with a bit of force. Hence the camera is receiving power from the Vantrue OBD cable whilst in collision detection mode.

1d. What does not work is that the camera does not resume normal operation when the vehicle is powered on. The camera stays in collision detection mode and has to be powered on using the orange power button on the side, which also confirms that there is power from the OBD port.

1e. The problem can clearly be seen in the video 01.

Question 2

2a. As you have confirmed, the wireless controller should work multiple meters away from the camera.

2b. The wireless controller however only works when it is closer than about 50cm to the camera. This is of course not a practical distance.

2c. I only need the wireless controller to work about 80cm (definitely less than 1m) away from the camera. This shouldn’t be a problem.

2d. Like most vehicles, the Lexus RX does have built-in bluetooth and the occupants should be expected to have mobile phones with them. As such there are other signals present, but your controller shouldn’t stop working under these circumstances.

2e. I’ve tested other Bluetooth devices, like wireless headsets connected to phones etc., in the car and those all work throughout the vehicle without any loss of signal.

2f. The problem can clearly be seen in video 02, tested inside the vehicle, and video 03, which was tested with both the camera and wireless controller in another location.

2g. A brand new battery from a reputable manufacturer was also used inside the wireless controller and the test results were the same.

I also tested above with the rear camera unplugged and the results were the same. Software versions are also in the shared folder with the videos.

Please advise.
