System Overview
Experience 4K video surveillance with the simplicity of reusing existing
coaxial infrastructure. The 4K HDCVI camera adopts a powerful Dehua
ISP and advanced 1/2.7" CMOS sensor, which provides superior high
quality images. In addition, the camera features broadcast quality audio
to provide enhanced supplementary evidence collection. Ultra-high defy-
nation 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 demanded.
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 technol¬
ogy 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.
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 con-
figuring a network.
Broadcast-quality Audio
Audio information is used as supplementary evidence in video sur-
veillance applications. The HDCVI camera supports audio signal transmis¬sion 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 col-
lected audio information.
Multiple-formats
The camera supports multiple video formats including HDCVI, CVBS,
and other two common HD analog formats in the market. This feature
makes the camera compatible with not only XVRs, but also most existing
HD/ SD DVRs. *
*Use OSD menu to switch HDCVI to other video formats. Use PFM820 UTC Controller to switch CVBS to
HDCVI video format.
Protection
The camera's outstanding reliability is unsurpassed due to its rugged de-
sign. 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 protectionagainst the
camera and its structure from the effects of lightning.
Smart IR
The camera is designed with microcrystalline LED IR illumination for best
lowlight performance. Smart IR is a technology to ensure brightness uni-
formity 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.
4K Real-time Image Display
Used together with 4K Real-time XVR, the camera can output 4K real-
time video stream with clear details and no lag or smear.
