@Solla-topee I found the solution, camera was going offline every time night vision switched on, the internet connection was fine, the 9v power plug that comes with the camera does not supply enough...

I have 3 camera 1 camera goes offline every night and can never get it back online until the next day, it's signal is -54db so don't no if it's Wifi related but my garden cam is -77db and has never...

Can you purchase a power cable extension for the Tapo c320ws camera 3rd party extensions all say 12 v but Tapo cam is 9v will a 12v extension be ok
