I've recently installed a curtain heater in a shop fit, however when it is turned on the cctv at the complex goes fuzzy. Its wired into the same board that the cctv is but in a different mcb. How can i get rid of the interferance without rewiring the heater somewhere else?

cheers

1) What kind of motor does the blower in the heater have?
2) Same phase or different phase as CCTV kit
3) Ban will come along with an answer that eliminates interference *and* saves the world ;)

If there's more than one CCTV camera, doe the other one work ok?

If so it's localised interference, not the mains supply.

Have the cables, CCTV to camera and feed to the heater been run beside each other?

If so try seperating then by 100mm and see if that's a quick fix.

If the CCTV camera is really that close to the unit and nothing else sorts it, could the CCTV be repositioned and then refocused so that it's a decent distance away?

I'd have thought it would need to be 3ft+ away as a minimum.

the heater is on the same phase as the cctv and as far a i can see doesnt go within a few foot of any cctv coax. the security room is about 3m away from the db, and only one monitor goes funny and 3 or 4 cameras on one multiplexer. Could it be intereferance on the supply or is it probably a coax too near the heater.
I'll check again for any cables going near the supply/heater

Yup.

The solution is to fit panels into the opening which are hinged, and thus can be temporarily swung out of the way to allow people to pass through the opening...
