DAHUA DH-HAC-EW2501P-0140B 5MP HDCVI IR-Fisheye Camera.
The 5MP HDCVI fisheye camera adopts a panoramic fisheye lens and
high performance image sensor, as well as a 10m IR range, enabling a full
overview and superior image details with 5MP resolution. That makes it
easy to collect evidence at any time 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 5MP resolution makes the camera an ideal choice for largesize businesses and places such as airports, stadiums, parking lots, and
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.
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 XVR, 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.
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
Long Distance Transmission
HDCVI technology guarantees real-time transmission at long distance
without any loss. It supports up to 700m transmission for 5MP 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 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 space.
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 outdoor lightning.
