System Overview :
Experience superior clarity of real-time 4Mega-pixel video with the
simplicity of using existing coaxial infrastructure. The 4MP HDCVI
camera presents high quality image with clear details and accurate color
rendition, and supports 120dB true WDR for applications under complex
dynamic range. It offers various motorized/fixed lens models with
multi-language OSD and HD&SD dual-output. The higher resolution and
complete features make the 4MP HDCVI camera an ideal choice for mid
to large-size business and common projects where both highly reliable
surveillance and construction flexibility are concerned.
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.
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 supports HDCVI and CVBS signal outputs simultaneously
with two BNC connectors. Multi-outputs facilitates construction in such
situations as debugging through a tester. It also offers the possibility for
cooperating with multiple devices including analog matrix or monitor.
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.
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 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 condition. Besides, the
advanced 3DNR effectively decreases the band width and saves the storage
Large Aperture Lens
The camera adopts high-end F1.5 large aperture lens. With higher amount
of absorbed light, the camera presents an impressive lowlight performance.
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 ±25% 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
