    I recently got a 2.4GHz wireless security cam for the house, but as our whole town is on a generator with noisy power, the picture from the receiver is crap, jumping flickering and scrolling.

    It is plugged into a UPS which is on a surge protector - is there anything else I can try to overcome the problem?

    I wouldn't think noisy power would cause that, the camera would regulate the AC power to DC at 12V or something.

    Is there any 2.4GHz networks in the area?
    My little wireless camera's do they same unless I shut down my network.

    Both the camera and receiver have separate plugpacks that converts to 8v DC. There is no other wireless anything running in the entire town (besides UHF radios).

    I speculate that it is the power as I noticed while watching tv later last night the same flickering going on, but only just barley visible.

    Won't have anything to do with power then. Must be interferance from another 2.4GHz source, or it is just a dodgy wireless camera/receiver. You aren't watching the camera on this TV that flickers are you? Tried moving the camera closer?

    Some cordless phones use that band as well. AV senders also. Could be interference from one or more of them.

    I didn't think of them, but again, there are only 2 of them within 1km of the camera & receiver - both mine, so I wouldn't think that would be the problem.

    Noisy mains could cause that sort of flickering, but it's more likely to be RF interference from microwaves, fluoros, etc. You can try getting a power board with a built in mains filter (as opposed to surge protection) as they will remove any RF noise on the AC line.
