Hello   @Das. 

It seems that the  System Led turns red on tapo camera, that means camera wifi connection drops

• Confirm tapo camera gets good signal strength from router, what is the RSSI on the camera? 

How to check the network connection stability of a Tapo Camera

Move camera closer to router and see if camera goes offline or not

• Make sure camera is connected to router directly, not through other AP or Range extenders
• Make sure tapo firmware in tapo app and tapo APP version are both up to date 
• Check if there is any Advanced settings on router like access control/ parental control/ Mac Filtering settings may affect the camera

Can I know what is the model of Wi-Fi router? Does camera connect to router directly or through extender? 

Can you share the Mac address of camera to us via private message?Thank you.
