4 Signals over 1 Coaxial Cable
HDCVI technology supports 4 signals to be transmitted over 1 coaxial
cable simultaneously, i.e. video, audio*, data and power. Dual-way data
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 800m(1080P)/1200m(720P)
transmission via coaxial cable, and up to 300m(1080P)/450m(720P) via
UTP cable.*
*Actual results verified by real-scene testing in Dahua’s test laboratory.
Simplicity
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.
Smart IR
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.
