History Playback

The platform cannot view historical replays

1. Verify that the device’s network connection is working properly: dial-up successful and signal strength greater than 19

   

2. Verify that the device’s TF/SD card is functioning properly:

   1. Disk status is normal.

      

   2. Insert the memory card into a computer and use Disk Utility to check its status.

3. Verify that the device is in ACC ON mode. If it is in ACC OFF mode, you can only view the footage during the “recording while engine is off” period.

4. The size of the memory card determines the recording duration; older video footage will be overwritten.

No audio during platform playback

1. For devices with a built-in camera channel, verify the device’s audio recording setting.

   

2. MDVR series devices require an external camera to support audio recording.

3. You can use platform commands or SMS commands to check or change the audio setting. For details, refer to Related Commands
