Installation and recorder compatibility

Use it for gates, parking lanes, loading areas, warehouse approaches and exposed entrances. Choose a lens that places the target at a useful size rather than using the widest view by default.

Use a compatible HDCVI/XVR channel, regulated 12 VDC power and correctly terminated coaxial cable or a suitable video balun. Select the camera output format only when required by the recorder. The camera is not an IP camera and does not connect directly to a router.

Choosing the correct lens, recorder and cable

Use a 5MP-capable XVR and confirm 5MP 16:9 support. Smart Dual Light 5MP operation may require XVR firmware V4.001.0000004.1.R.220323 or later, as specified by Dahua.

Before dispatch, confirm the ordered lens, PAL recording mode, DVR resolution support, audio compatibility and required cable distance. Published illumination distances are measured under controlled conditions; real performance changes with mounting height, scene reflectivity, lens choice and ambient light.
