Analogue HDCVI cameras are designed for CCTV systems that send HD video over coaxial cable to a compatible recorder. Our range includes over 10 Dahua cameras in turret, dome and bullet styles. They suit homes, shops and offices, especially where coaxial cabling is already in place.
How to choose an HDCVI camera
Resolution. Our range includes models at 1920 x 1080 (2 MP), 2880 x 1620 (often marketed as 5 MP) and 3840 x 2160 (4K). For a general view of an entrance or a room, 2 MP is usually enough. If you need to recognise faces or number plates, a higher resolution is worth considering, but the recorder must support it too.
Form factor. Turret cameras are easy to aim, and their infrared emitters often cause less reflection from the cover than in many dome models. Dome cameras are harder to turn by hand, which suits more exposed locations. A bullet camera is clearly visible and often discourages tampering. In our range, tilt typically runs from 0 to 78° or 0 to 90°, which matters when mounting on a wall or under an eave.
Night vision. In our range, the infrared distance runs from 25 to 80 m, with between 2 and 4 illumination LEDs. The manufacturer's figure is measured in good conditions, so real-world distance can be shorter. A small yard or doorway needs about 25 m, while longer areas call for 60 m or more. Also check minimum illumination and aperture: the lower the f-number (for example 1.6), the more light reaches the lens.
Compatibility and power. An HDCVI camera needs a recorder that supports HDCVI, such as an XVR or HCVR type. Many cameras need a separate power supply, so check the voltage and cable length before buying. Some cameras can switch to other analogue formats, but this is listed in each model's specification.

Frequently asked questions
How does an HDCVI camera differ from an IP camera?
An HDCVI camera sends video over coaxial cable, while an IP camera sends data over a network cable or wirelessly. HDCVI is often easier to install where coaxial cabling already exists. IP cameras suit setups that need more advanced network features.
Will an HDCVI camera work with any recorder?
No, it needs a recorder that supports HDCVI. Many modern XVR recorders accept several analogue formats, but you should confirm this in the specification. Also make sure the recorder supports the resolution of the camera you choose.
What night vision distance do I need?
It depends on the area: a small yard or entrance can be covered with 25 m, while a longer stretch calls for 60 m or more. Our range includes models from 25 to 80 m. Real distance also depends on surroundings, since light surfaces reflect more infrared light.
Can I use existing coaxial cable?
Often yes, because HDCVI was designed to carry HD video over coaxial cable. The cable should be in good condition with firmly attached connectors. If it is very old or long, picture quality may suffer, so test one camera first.
