What you'll notice
Analog picture degrading over months — contrast fading, noise creeping in, then video loss in damp weather.
Why it happens
Moisture reaching an unsealed outdoor termination; coastal air accelerates it dramatically.
How we fix it
Cut back to bright copper, crimp a new compression BNC, and seal the joint in a proper enclosure — plus a check of every other termination from the same install, which usually shares the disease.
Still not working?
If the checks above haven't restored your connectors, this usually needs a technician. Our CCTV Repairs service covers exactly this fault.
