System Overview
Cooper Series offers simple and highly cost-effective HDCVI solutions.
It offers 24/7 reliable monitoring with high-quality image performance,
saving both product and labor costs. It is also highly guaranteed by
Dahua quality standard.
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 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.
Broadcast-quality Audio
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 information.
Long transmission
HDCVI technology guarantees real-time transmission at long
distance without any loss. It supports up to 700 m transmission for
2MP/5MP/8MP HD video via coaxial cable, and up to 300 m via UTP
cable.
*Actual results were verified by real-scene testing in Dahua’s test laboratory.
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 detection. The camera supports 11 languages
for OSD menu, namely, Chinese, English, French, German, Spanish,
Portuguese, Italian, Japanese, Korean, Russian, and Polish.
Smart Illumination
The camera is designed with 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 IR LEDs to compensate for the distance of
an object, and prevents IR LEDs from overexposing images as the object
comes closer to the camera.
Simplicity
HDCVI technology inherits the inherent feature of simplicity from traditional
analog surveillance system, making itself the 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 high-definition video surveillance without the hassle of
configuring a network.
Protection (IP67, wide voltage)
IP67: The camera passes a series of strict test on dust and soak. It has
dust-proof function, and the enclosure can work normally after soaking in
1 m deep water for 30 minutes.
Wide voltage: The camera allows ±30% (for some power supplies)
input voltage tolerance (wide voltage range), and it is widely applied to
outdoor environment with instable voltage.
