/ 01Overview
What thisactually involves.
HDCVI, AHD and TVI let you keep existing coaxial infrastructure and still record in 1080p or higher. For many shops and older buildings, this is the fastest and least disruptive route from a tired analogue system to something genuinely usable in an incident.
/ 02Do you need this?
Signs it's time to act
- An older analogue system still runs but the picture is unusable
- Coaxial cable is already routed through the building
- Re-cabling would mean chasing walls or closing the premises
- You want an HD upgrade on a tighter budget
/ 03Capabilities
- 011080p to 5MP over existing coaxial runs
- 02Long-distance transmission without repeaters
- 03Hybrid recorders — analogue and IP together
- 04Built-in audio over the same cable
- 05Zero re-cabling in most retrofits
/ 04What's included
- Assessment of existing cable condition
- Camera and recorder replacement
- Power supply and balun upgrades
- Recording schedule configuration
- Old-system removal and disposal

What moves the price
We quote after a survey rather than over the phone, because these are the things that actually change the number — and none of them are visible from a phone call.
- 01Condition of the existing coaxial cable and connectors
- 02Resolution you upgrade to — 1080p through 5MP
- 03Whether power supplies and baluns also need replacing
- 04Hybrid recorder capacity if you plan to mix in IP later

/ 07Common questions
Usually. We test the runs first — if the coax is sound, only cameras and the recorder are replaced. Where a cable has failed we quote that run separately rather than replacing everything.
Close at the same resolution, but IP scales higher and brings analytics. HD-over-coax exists to give you a genuine HD picture without re-wiring the building.
