Removing mic hum

Hi - I have a couple of orb cameras in use in a property and there is a 50Hz hum that is present on both of them on both live and playback. I have tried playing with the mic sensitivity to see if this fixes it, but it doesn’t. We have tried plugging the cameras into different plug sockets and even in different locations, and the problem persists.

Any more ideas at all?

Thanks, Andy
