System Overview
Experience 5MP full HD video and the simplicity of using existing cabling
infrastructure with HDCVI. The Cooper series 5MP HDCVI camera features
a compact design and offers a high quality image at a friendly price. It
offers various vari-focal/fixed lens models with a multi-language OSD
and HD/SD switchable output. Its structural flexibility and high costperformance makes the camera an ideal choice for SMB solutions.

Functions
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 for 5MP HD video tran-smission
via coaxial cable, and up to 300m via UTP cable.*
*Actual results verified by real-scene testing in Dahua’s test laboratory.

Simplicity
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.

Smart IR
The camera is designed with IR LED 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.

Multi-formats
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 OSD menu or by PFM820(UTC controller). This
feature makes the camera to be compatible with not only HCVRs but also
most end users’ existing HD/SD DVRs.

Multi-language OSD
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 detect. The camera supports 11 languages for
OSD menu, namely, Chinese, English, French, German, Spanish, Portuguese,
Italian, Japanese, Korean, Russian and Polish.

Protection
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.
With working temperature range of -30 °C to +60 °C (-22 °F to +140 °F), 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.
