Experience superior clarity of real-time 4 Megapixel 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 360° panoramic view and several kinds of dewarping mode
with multi-language OSD and HD&SD dual-output with our backend. 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 450m 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.
360° panoramic view
Equipped with a fisheye lens for 360° surround view (ceiling/floor mount) or
180° panoramic view (wall mount) and high resolution with no blind spot.The
cameras are able to provide coverage of wide, open areas, such as airports,
shopping malls, retail stores, offices and more.So you wil get a whole scene
just with one fisheye camera.
Fisheye dewarping is a function to solve the serious distortion problem of
the circular panoramic view and you will use up to 10-modes dewarping
mode for different installations with our XVR or on the web.Every dewarping
area is adjustable and optional as you want.
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 space.
The camera’s outstanding reliability is unsurpassed due to its rugged
design. The camera is protected against vandalism with IK10-rated, making
it suitable for most environment such as retail stores,manufacturing and
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 lightning.
