Common Issues

The App cannot find the device

1. Make sure the device is turned on and Bluetooth is enabled on your phone.
2. Move the phone closer to the device.
3. Check the App's Bluetooth and Nearby Devices permissions.
4. Disconnect any other phones from the device.
5. Turn your phone's Bluetooth off and on, then scan again.

WiFi configuration fails

1. Check the network name and password again.
2. Move the device closer to the wireless router.
3. Temporarily avoid public networks that require browser-based sign-in.
4. For a Chinese network name, select it directly from the list in the App to avoid copying unusual characters manually.
5. After configuration, wait for the App to display the current network name.

The App says the SD card is unavailable

• Make sure the SD card is fully inserted.
• Stop recording and shut down normally before reinserting the card.
• Check on a computer that the SD card is readable and has free space.
• Back up the data before formatting or replacing the SD card.

The blue light keeps flashing rapidly after starting

The device has not completed recording warm-up. Do not treat this time as a valid recording.

1. Wait for a while to see whether the light becomes solid blue.
2. Make sure the SD card is available and the battery has enough charge.
3. Stop this recording and wait for the light to become solid green.
4. Start another short test recording.
5. If it fails again, preserve the device's current state and contact support.

The green light keeps flashing rapidly after stopping

The device may still be finalizing large files. Keep it powered and do not remove the SD card. If this takes noticeably longer than usual, check the status in the App and note the recording duration.

Preview is unavailable while recording

This is normal. During an active recording, the device stops live preview and prioritizes hardware resources for reliable capture. Stop recording and wait for the device to return to standby before opening the preview again.

A video cannot be played or a file is incomplete

• Do not delete any files from the session.
• Keep the metadata.json in the same folder.
• Check whether the other three videos are normal.
• Note whether the device lost power, the card was removed, or the battery remained low for a long time.
• Send the entire session folder to technical support for analysis.

The device is temporarily unreachable after an update

Network and Bluetooth services restart briefly during installation. Wait until the device returns to a solid green light, then close and reopen the App. If the device prompts you to restart, first confirm that the update is complete, then restart normally.
