Experience 4K video surveillance with the simplicity of reusing existing
coaxial infrastructure. The 4K HDCVI camera adopts a powerful Dahua
ISP and advanced 1/2″ image sensor, which provides superior high quality
images. It also supports Starlight and 120dB true WDR for a clear image
in poor lighting conditions. In addition, the camera features broadcastquality audio to provide enhanced supplementary evidence collection.
Ultra–high definition and a complete set of features makes the 4K HDCVI
camera an ideal choice for mid to large-size businesses and projects
where both highly reliable surveillance and construction flexibility are
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 4K and 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.
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
Audio information is used as supplementary evidence in video surveillance
applications. The HDCVI camera supports audio signal transmission over
coaxial cable. In addition, it adopts unique audio processing and transmission
technology that best restores source audio and eliminates noise, guaranteeing the quality and effectiveness of collected audio information.
The camera supports multiple video formats including HDCVI, CVBS, and
other two common HD analog formats in the market. A DIP switch located on
the cable allows you to quickly toggle formats, further simplifying installation
and debugging. This feature makes the camera compatible with not only
XVRs, but also most existing HD/SD DVRs.
Wide Dynamic Range
Embedded with industry leading wide dynamic range (WDR) technology,
vivid pictures are achieved even in the most intense contrast lighting
conditions. True WDR (120dB) optimizes both the bright and dark areas of a
scene at the same time to provide usable video.
3DNR is a noise reduction technology that detects and eliminates random
noises by comparing two sequential frames. Dahua’s advanced 3DNR technology allows remarkable noise reduction with little impact to sharpness,
especially under limited lighting conditions. Besides, the advanced 3DNR
effectively decreases the bandwidth and saves the storage space.
The camera’s outstanding reliability is unsurpassed due to its rugged design.
The camera is protected against water and dust with IP67 ranking, making it
suitable for indoor or outdoor environments.
Supporting ±30% input voltage tolerance, this camera suits even the most
unstable power supply conditions. Its 4KV lightning rating provides protection against the camera and its structure from the effects of lightning.
