HD-TVI cameras
HD-TVI is an analogue-over-coax standard that carries HD video on RG59/coax cabling, giving installers a way to upgrade existing analogue runs without re-cabling to IP. This range covers HD-TVI camera products spanning the fixtures, form factors and specs typically needed for retrofit and budget-conscious analogue jobs.
How to choose
- Existing cabling — HD-TVI suits sites with coax already in the wall; check run length and connector type before quoting.
- Form factor — dome, bullet or turret bodies suit different mounting positions and discretion requirements on site.
- DVR compatibility — confirm the recorder accepts HD-TVI signal and supports the resolution and channel count of the cameras selected.
- Environment — match housing rating to indoor or exterior installation conditions.
- Lens and field of view — fixed or varifocal lenses determine coverage per camera, affecting how many units a job needs.
Because this is a coax-based standard rather than a networked one, buyers should plan cable runs and DVR inputs alongside camera selection rather than treating each camera as a standalone IP device.
Turbo HD — frequently asked questions
What is HD-TVI and how does it differ from IP cameras?
HD-TVI carries HD video over coax cabling to a compatible DVR, rather than over a network switch like an IP camera; it suits retrofitting existing coax runs.
Can HD-TVI cameras use existing analogue coax cabling?
Yes — HD-TVI is designed to run over standard coax (e.g. RG59), which is the main reason it's chosen for retrofit jobs over full IP re-cabling.
Do I need a specific DVR for HD-TVI cameras?
You need a DVR that supports the HD-TVI signal and matches the resolution and channel count of the cameras you select from this range.
