Every fault below comes from real call-outs across Durban and surrounding areas. Some have a quick check you can try yourself before booking anyone — where that's true, we say so. When a visit is needed, the diagnosis is done with a signal meter, quoted before work starts, and covered by our 12-month workmanship warranty. New to this part? Start with the connectors component guide.
1. Corroded BNC connector
What you'll see: 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.
2. Loose or badly made RJ45
What you'll see: An IP camera that drops when its cable is touched, negotiates at low speed, or loses PoE intermittently.
Why it happens: Untwisted pairs at the plug, the wrong wiring order, no strain relief, or a plug never fully crimped.
How we fix it: Re-terminate to T568B with proper strain relief and verify with a tester — every pair, both ends, PoE under load.
3. DC power jack failure
What you'll see: A camera that reboots when wind moves its cable, or a connector warm to the touch.
Why it happens: A loose barrel connection arcing under load, undersized joints, or corrosion inside the jack.
How we fix it: Replace the connector, support the cable so the joint carries no mechanical load, and confirm voltage at the camera under full night-time load.
Symptom doesn't match any of these?
Faults overlap — a "connectors problem" is sometimes another link in the chain wearing a disguise. Describe what your system is doing on 069 423 8290 (or WhatsApp a photo of the error screen) and we'll tell you which component it actually sounds like, free, before anything is booked.
