Wireless outdoor camera does not use outlet
I have a wireless outdoor camera that has a battery, but is also plugged in. All equipment is brand new. The outlet works. The brick works. All connections are secure. However, the camera will only run on battery. I have three other cameras--2 outdoor, 1 indoor--that all run from the outlet. The problem camera has been removed and reinstalled. Nothing works; it still only runs from battery. Anyone have any ideas?
Update to add: Tried to install camera without battery (as battery needed to charge!) and would not install. No light...indicating no power, even though the outlet has power.
