DAHUA 2MP HDCVI Analog IR Vari Focal Dome Camera DH-HAC-D3A21P-VF
Experience 1080P full HD video and the simplicity of using existing cabling
infrastructure with HDCVI. The Cooper series 1080P HDCVI camera
features a compact design and offers a high-quality image at a friendly
price. It offers 2.7-12mm, varifocal lens models, with a multi-language
OSD and HD/SD switchable output. Its structural flexibility and high-cost performance make the camera an ideal choice for SMB solutions.
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 a control signal or triggering the 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 distances
without any loss. It supports up to 800m(1080P)/1200m(720P) transmission via coaxial cable, and up to 300m(1080P)/450m(720P) via UTP
*Actual results verified by real-scene testing in Dahua’s test laboratory.
HDCVI technology inherits the born feature of simplicity from the traditional
analog surveillance systems, 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
the approach enables full HD video surveillance without the hassle of configuring a network.
The camera is designed with IR LED illumination for the best lowlight
performance. Smart IR is a technology to ensure brightness uniformity
in B/W images under low illumination. Dahua’s unique Smart IR adjusts to
the intensity of the camera’s infrared LEDs to compensate for the distance of
an object and prevents IR LEDs from overexposing images as the object
comes closer to the camera.
The camera supports multiple video formats including HDCVI, CVBS, and
other two common HD analog formats in the market. The four formats can
be switched over through the OSD menu or by PFM820(UTC controller). This
feature makes the camera to be compatible with not only XVRs but also most
end users’ existing HD/SD DVRs.
OSD menu provides multiple image adjustments and function settings
to meet the requirements of different monitoring scenes. The OSD menu
includes configurations such as backlight mode, day/night, white balance,
privacy mask, and motion detection. The camera supports 11 languages for
OSD menu, namely, Chinese, English, French, German, Spanish, Portuguese,
Italian, Japanese, Korean, Russian, and Polish.

suitable for indoor or outdoor environments.
With a working temperature range of -40 °C to +60 °C (-40 °F to +140 °F), the
the camera is designed for extreme temperature environments.
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 lightning.
