transmission allows the HDCVI camera to interact with the HCVR, such as
sending control signal or triggering alarm. Moreover, HDCVI technology
supports PoC for construction flexibility.
* Audio input is available for some models of HDCVI cameras.
Long Distance Transmission
HDCVI technology guarantees real-time transmission at long distance
without any loss. It supports up to 700m for 4MP HD video via coaxial
cable, and up to 300m via UTP cable.*
*Actual results verified by real-scene testing in Dahua’s test laboratory.
HDCVI technology inherits the born feature of simplicity from traditional
analog surveillance system, making itself a best choice for investment
protection. HDCVI system can seamlessly upgrade the traditional analog system without replacing existing coaxial cabling. The plug and
play approach enables full HD video surveillance without the hassle of
configuring a network.
The camera is designed with microcrystalline LED IR illumination for best
lowlight performance. Smart IR is a technology to ensure brightness
uniformity in B/W image under low illumination. Dahua’s unique Smart IR
adjusts to the intensity of camera’s infrared LEDs to compensate for the
distance of an object, and prevents IR LEDs from overexposing images as
the object come closer to the camera.
The camera supports multiple video formats including HDCVI, CVBS and
other two common HD analog formats in the market. The four formats can
be switched over through OSD menu or by PFM820 (UTC controller). This
