5. Parking Monitoring

The parking monitoring mode requires a three-core step-down wire connection; ordinary car chargers cannot trigger this function.

Parking Monitoring Function Triggered Time Setting: For time-lapse recording cycles, options include 6 hours, 12 hours, 24 hours, and 48 hours. Setting a 6-hour time means the machine will automatically shut down after continuously recording for 6 hours after the parking monitoring function is triggered.

Low Voltage Protection Settings: Options are 11.2V, 11.5V, and 11.8V. When 11.2V is set, the machine will automatically shut down if the car battery voltage drops below 11.2V.

Troubleshooting

Under normal operating conditions, if the product has problems, please refer to the following solutions:

1. Could not take photos/video: Check if the TF card has enough space and is not locked.
2. Recording stops automatically: Due to large high-definition video data, use an SDHC compatible high-speed TF card (C10 identity).
3. Error replaying pictures and videos ("File" prompt): An error occurred with TF card memory data, resulting in incomplete files. Use the Car DVR "Format" function to reformat the card.
4. Image is foggy: Check the lens for dirt and fingerprints. Before shooting, wipe the lens with lens paper.
5. Recorder does not work: Press the reset key with a sharp object and then start it again to restore normal operation.
6. First-time network access/local photo album: Ensure network access permission is granted and the local photo album is accessible.

7. Mobile phone cannot connect to the product: First, check if the mobile phone is connected to other Wi-Fi hotspots. The app can only connect to the recorder when the phone's Wi-Fi is connected to the recorder. If connection fails (e.g., at home), verify the phone's Wi-Fi settings are connected to the recorder's Wi-Fi.
8. Real-time picture is stuck: This is generally related to the Wi-Fi signal. If the mobile phone is too far from the recorder, the Wi-Fi signal is weak, causing the real-time picture to freeze. Additionally, too many Wi-Fi signals around the recorder can interfere and cause the real-time picture to jam.
9. Preview speed in the album is very slow: This may be due to too many video files on the TF card, causing a timeout when obtaining file information. Consumers are advised to format TF cards regularly.
10. Multiple clients connecting: Only one mobile phone can link at a time. If a mobile phone cannot connect, rule out whether the recorder is already connected to other mobile phones.
11. Using a computer to play video recordings: The product uses H.264 compression format (MOV or MP4). Many built-in playback software on Microsoft Windows computers (like Windows Media Player) do not support H.264 encoding, which may result in playback issues (choppy, frozen frames, unsynchronized audio/video). It is recommended to download other professional playback software (e.g., PotPlayer).
