Hi, 
Usually, you can refer to the instructions below to troubleshoot if your camera keeps going offline.
What should I do if my Tapo smart device keeps losing connection or going offline?
 

Please confirm the following information if the same phenomenon persists.
  1. When the camera is working, please go to its Device Settings > Device Info page, tap the Wi-Fi icon, and check the RSSI value.
  2. Is the LED solid red or flashing red when the camera goes offline? How do you recover the connection, such as by rebooting the camera?
  3. What's the model number of your router? When the camera goes offline, do you have an internet connection on your phone/tablet when connecting to the same router's Wi-Fi as the camera?

Best Regards
