The 4K HDCVI fisheye camera adopts a panoramic fisheye lens and 1/2″
8MP high performance image sensor, as well as a 15m IR range, enabling
a full overview and superior image details with 4K resolution. That makes
it easy to collect evidence at any time of day for effective playback and
analysis. With the use of advanced algorithms, more than 10+ dewarping
modes are available on the XVR (select models) and mobile client. Its
panoramic view and 4K resolution makes the camera an ideal choice for
large-size businesses and places such as airports, stadiums, parking lots,
and shopping malls.
Fisheye Panoramic View
HAC-EBW3802 offers a panoramic view based on three installation
modes(ceiling/ground/wall)with up to 95% sensor pixel utilization.As a
result you can recognize a person’s face over 10 meters away.The camera
is able to provide a crystal clear image and broad coverage of wide and
open areas, such as airports, shopping malls, retail stores, offices and
more.So you wil get a overall sight just with one fisheye camera over coax.
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 HDCVR,Web and SmartPSS.Every
dewarping area is adjustable and optional as you want.
On-Device Lens Distortion Correction
On-device lens distortion correction is another great innovation of HDCVI
technology for correcting the fisheye panoramic image to a 16:9 full screen
with two optional modes by the camera itself.One is Vertical&Horizontal
(V&H)mode which can provide an image without any distortion and angle
of view is about H:170°,V:88 °.Another is Vertical(V) mode that can enable
the camera to output an image with H:176°,V:73 ° view angle.
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
provides full HD video surveillance without the hassle of configuring a
The camera supports HDCVI and CVBS signal outputs simultaneously with
two BNC connectors. Multi-outputs facilitates construction in situations such
as debugging with a tester. It also offers the possibility for cooperating with
multiple devices including analog matrix or monitor.
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 outdoor lightning.
