Buzzing sound from floodlight cam wired pro

There is a constant buzzing/hissing sound from the camera. Checked all grounds and they are adequate. How do I get it to stop this

Hi @Beebarf. The Floodlight Cam Wired Pro should not be making any buzzing noise. I suggest disconnecting the Floodlight Cam from power and contacting a qualified electrician to access the wiring setup.
