If the camera is beeping continuously, it means the camera is not in the recording, most of such issues are related to the microSD card. You can try the instructions below to solve the issue: 

① Format the card to FAT32 first, you can format the card from camera menu settings or use the APP to format. For deep formatting, you can also use the tool to format the card deeply. 

If the issue is not solved,  we suggest you use a new card. You can refer to this when choosing a card.

② If you use more than 1 channel, please unplug the back cameras to test if an unstable connection causes the issue.

Please try to disable the VIOFO APP from accessing cellular data in the setup as the pic below.

Please also turn off phone VPN if issue persists.
