Q: What should I do when the product has problems that I cannot handle?
A: Record product model and software version number, submit detailed problem description to our technical support engineer for analysis.
The more detailed you describe, the more convenient our analysis will be.

Q: What if the car host device does not have video output?
A: 1. Check the boot status of the host. Check the device input power, check the power line wiring is correct, whether the ground wire back to the battery, the power line insurance is intact; at the same time check the host power supply red and yellow line is normal, if only one line power supply, then the host Can't start it.
2. Check if the display is powered and if the display video switches to AV and the corresponding channel status.

3. It is recommended to connect the recorder directly to the battery power output of the car. Please note that do not pick up the power output of the generator on the vehicle, because the generator may generate instantaneous high voltage during startup and damage the recorder.
4. After the video camera is connected to the camera, the startup power exceeds 30 watts (power consumption varies depending on the external device). The power supply must be able to provide more than 30 watts of power.
5. All power connections to the recorder must be sufficiently thick to withstand more than 60 watts of power. (For example, when the onboard power supply output voltage is 12V, the power cord must be able to withstand more than 5 amps of current)
6. It is recommended to wear a wear-resistant, heat-resistant, waterproof, and oil-resistant casing on the outside of the power cord. Because of long-term vibration on the vehicle, it can cause short circuit or open circuit due to friction.
7. The power cord is located near the positive end of the power output on the vehicle. A 10 amp fuse box is required. In case of a short circuit in the power line, the power on the car will be burned.

Q: The device is turned on, and the hard disk is also installed, but what should I do if it is not recorded?
A: 1. Check if the HDD/SD is formatted after installation. Unformatted HDD/SD cannot be used. Go to Main Menu - System Settings - Format to format the newly installed HDD/SD.
2. Whether the recording channel is closed or not, whether the scheduled recording is set, and no recording is performed within the recording period.
3. Check that the hard disk is in good contact and the front panel HDD/SD lamp is lit.

Q: The video file is missing, or there is no video file in a certain period of time?
A:1. By determining the time period determined in the first video file after the final video file is lost and restored.
2. Confirm whether the host has not booted during that period of time. For example, the host that stops parking, loading, unloading, etc. does not set a time-lapse recording.

GPS related issues
Q: GPS module exists but no coordinate information?
A: 1. Check if the GPS module is present.
2. Confirm whether the GPS antenna contact is good and whether the antenna is disconnected. It is recommended to place it in a place where the signal is strong.
Vehicle glass shielding will block the GPS signal.
3. If it is tested in the room, the GPS antenna is in the room and the signal is shielded. It is recommended to place the GPS antenna outdoors.
4. The impact of the surrounding environment such as trees, tunnels, driving around high buildings and elevated roads, thunderstorms, etc., may result in no signal of GPS, or receive a wrong signal.

Q: Is there a difference in GPS location on the map?
A: If the GPS module has been located, it means that the signal is valid. There are many reasons for the problem of deviation. Government restrictions, error tolerances, GPS signal interruptions, etc.; actual satellite maps may deviate due to safety considerations. General maps can be solved using GPS calibration. problem.

Other related issues
Q: Some channels have a black screen?
A: The black screen of certain channels is found on the monitor screen. The possible causes are as follows:
There is no video connection on this channel; the camera connected to this channel is damaged or abnormally working; if the power of the camera is taken from the device, the voltage provided by the device may be insufficient; the cable connecting this channel is not in good contact or damaged;

Q: Can't play back video files when playing back on a PC?
A: The possible causes are as follows: No video file path or video file is selected. Please select the path of the video file before playback; the local video file is corrupted, resulting in unreadable;
