What you'll notice
Rolling bands, grain, ghosting or dropouts — often correlating with pumps, gate motors or fluorescent lights switching.
Why it happens
Video cable run alongside mains power, unshielded cable near noisy equipment, copper-clad aluminium cable, or ground loops.
How we fix it
We re-route offending sections with proper separation from power, replace substandard cable, and fit isolation where ground loops are the cause.
Still not working?
