Why does the device show offline?

Delay mode: Refer to the delay setting time. If the camera's last online time exceeds the Delay time (the device's 
last online time can be queried in the APP), the device is not communicating normally and will display the offline 
status.

Real-time mode: To ensure battery life, the 4G module real-time command will take effect every 2 hours in real time mode, but the device will refresh the status information every 2 hours. If there is no normal update, the device is not communicating normally and will display the offline status.

The offline status may be related to the weak signal of the device location and the delay in synchronizing information. 
Or the device is low on battery and has been turned off, resulting in no updated information. Please check the above 
possible reasons. 
If you still cannot solve it, it is recommended to contact the store for consultation.
