System Overview
Experience 4 megapixel video with the simplicity of reusing existing
coaxial infrastructure. The 4MP starlight HDCVI camera presents a high
quality image with rich details even under extreme low-light conditions.
The camera also features broadcast-quality audio to provide enhanced
supplementary evidence collection. It offers various motorized/fixed lens
models with 120dB true WDR and HD/SD switchable output. The higher
resolution and starlight feature makes the 4MP HDCVI camera an ideal
choice for mid to large-size businesses and projects where both highly
reliable surveillance and construction flexibility are needed.

Functions
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 700m transmission 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.

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.

Starlight
With the adoption of large sized high performance sensor, the camera is
able to provide incomparable performance even under extreme lowlight
environment. The starlight feature allows more details to be captured
and accurate color to be recognized at night or in scenes with limited
illumination.
