Dahua Releases 4MP P/T/Z HD-Over-Coax Camera


Dahua Technology announces the release of a HD-over-coax 4-megapixel 30x optical zoom p/t/z camera it says is first to the market. Part of Dahua’s HDCVI 3.0 series, the camera can integrate with legacy video surveillance systems.These newest additions to the HDCVI 3.0 Ultra Series bring high value to installers who are seeking optimal distance and clarity, along with plug-and-play installation, when updating existing coaxial infrastructure.

Dahua’s HDCVI technology works by simultaneously transmitting three signals (video, audio and control) over a single cable at a distance of up to 700m for RG6 cable and 500m for RG59.

Dual-way data transmission lets HDCVI cameras communicate with a DVR to send control signals or trigger alarms. A BNC video output connection allows the cameras to integrate seamlessly with various devices, including analog matrix systems and monitors.

Dahua’s new HDCVI 3.0 4-megapixel p/t/z cameras are available in four different form factors: two indoor/outdoor IR 30x p/t/zs, an indoor/outdoor p/t/z, and an indoor 30x p/t/z.
The cameras feature true WDR technology for low-light conditions as well as defog capabilities that dynamically adjust contrast settings. Designed for harsh environments and extreme temperatures, Dahua says the cameras’ housings have been subjected to rigorous dust and water immersion tests.
