Chapter 3 Powering and Charging

3.1 Camera Charging

Note: After charging is complete, disconnect the cable and securely close the waterproof cap.

3.2 Powering On

Double-press the power button to turn the camera on or off. When powered on, the blue indicator will light up.

Chapter 4 Connection and Pre-Installation Test

Before mounting the camera, check that the WR2 camera, wireless video receiver, CB7 Series AI Box, and car stereo are working properly. The camera and wireless video receiver are pre-paired before shipment.

1. Power on the car stereo, then use the USB A-C Cable included with the CB7 Series AI Box to connect the CB7 to the car stereo. Then, enter the CB7 system from the car stereo screen.
2. Use the “AV to USB-C Cable” to connect the CB7 Series AI Box’s AV Port to the wireless video receiver’s USB-C port.

1. Double-press the camera power button to turn on the camera. When pairing is successful, the blue indicators on both the camera and the wireless video receiver will stay on.
2. Press the WAKE/PAIR button on the wireless video receiver once. The WDVC App will open and display the camera view within a few seconds.
3. By default, the camera operates in Power-Saving Mode and will automatically exit the WDVC App after about 2 minutes.

Note: The camera view will only appear after you press the WAKE/PAIR button on the wireless video receiver. If you open the WDVC App manually, press the WAKE/PAIR button once to wake the camera and display the camera view. After you press the button again to close the camera view, the WDVC App may automatically close after about 1 minute.

Note: For the best experience, use the WAKE/PAIR button on the wireless video receiver to open or close the WDVC camera view. Opening the WDVC App from the app list is not recommended, as the camera view still needs to be started with the WAKE/PAIR button.

To switch to Continuous Rear View Mode, make sure the camera view is already displayed, then double-press the WAKE/PAIR button on the wireless video receiver.

If the camera is not paired:

1. Press and hold the receiver’s WAKE/PAIR button until the blue light flashes rapidly.
2. Then press and hold the camera’s power button until the red light appears and changes to fast blue flashing.
3. When pairing is successful, the blue indicator light will turn solid.

Chapter 5 Installation

Due to differences in license plate styles between North America and Europe, the recommended mounting position may vary slightly.

Chapter 8 Troubleshooting

8.1 No Video or Connection Issues

If the camera takes a long time to display video on your car stereo, frequently freezes or buffers, or fails to show any video, the issue may be caused by a weak wireless signal between the camera and the receiver box. Connection interference can be caused by structural elements of your vehicle.

How to Improve Wireless Signal:

• Adjust the receiver’s antenna

Open the WDVC app and check the signal strength. If it is below 60%, try rotating the receiver’s antenna in different directions to improve the signal to 60% or higher.

• Reposition the camera

Rotate and adjust the camera’s vertical angle. Adjust the distance between the antenna and the vehicle’s trunk metal. Try to point the antenna toward the sky.

Remove the camera from its bracket and temporarily flip it upside down. Reinstall the camera on the license plate or in a different location. When the camera is mounted with the ATOTO logo facing downward, it will automatically flip the video on your display device to ensure the image is correctly oriented. Flipping the camera may change the position of the wireless antenna and, in some cases, improve connection quality.

8.2 Cold Weather Issues

Low temperatures may reduce battery performance and affect connection. If the battery is below 20%, recharge the camera.

8.3 Camera Paired but No Video Display

If the camera’s battery is fully charged and the indicator light is slow-blinking blue, but no video appears on your car stereo, follow these steps:

Possible Cause: Camera Not Paired Successfully

Solution: Press and hold the WAKE/PAIR button on the receiver box for 3 seconds to enter pairing mode. The receiver’s indicator light will change from slow-blinking blue to fast-blinking blue and remain in pairing mode for 15 seconds. If pairing is successful within this time, the light will turn solid blue.

Camera Pairing Process:

Press and hold the camera’s power button for 3 seconds to enter pairing mode. The indicator light will briefly turn red, then switch to fast-blinking blue. Once pairing is successful, the light will turn solid blue.

After Successful Pairing:

Open the WDVC App on your car stereo. The camera feed should appear in the app. By default, the camera operates in Power-Saving Mode and will automatically exit the App after 2 minutes.

8.4 Unstable Signal or Intermittent Connection

Possible Causes:

The camera and receiver are installed beyond the effective wireless range.

There are metal structures or enclosures between the two devices that interfere with signal transmission.

Recommended Solution:

For optimal performance, install the camera and receiver within an open-air distance of approximately 7 meters (23 feet).

Avoid placing large metal objects or multiple layers of metal (such as trailer walls, toolboxes, or vehicle frames) between the camera and receiver.

If the layout limits placement options, consider repositioning the receiver closer to the camera to maintain a clear signal path.
