First, please check the exact error message displayed on your night vision device.

- "NO SD Card": Ensure that the SD card is properly inserted. Additionally, inspect the SD card slot on the device for any signs of damage.

- "SD Card Error" or frequent "Format SD Card" prompts: These messages typically indicate that you are using an incompatible or low-quality SD card.

It may also suggest that the SD card is old or worn out and no longer functioning properly.

Here are some steps you can take to resolve these issues:

1. Use a High-Quality SD Card: Select a reputable brand of high-speed SD card that meets the specifications required by your night vision device.

2. Inspect the SD Card: Regularly check the physical condition of your SD card. If you notice any damage, consider replacing it.

3. Manage Storage Space: Ensure that there is ample free space available on your SD card. Delete unnecessary files, and if needed, format the SD card using your computer.

4. Check Firmware: If the issue persists, please provide the firmware version of your night vision device. This information will assist us in determining whether a firmware update is necessary.

If the issue persists, please contact customer support for assistance.
