System Overview
Experience 5MP full HD video and the simplicity of using existing cabling
infrastructure with HDCVI. The Pro series 5MP HDCVI camera features
a compact design and offers a high quality image at a friendly price.
It offers various motorized/fixed lens models with 120 dB true WDR
and 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.
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.
Long Distance Transmission
HDCVI technology guarantees real-time transmission at long distance
without any loss. It supports up to 700 m for 5MP HD video via coaxial
cable, and up to 300 m 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.
Starlight
With the adoption of large sized high performance sensor, the camera is
able to provide incomparable performance even under extreme lowlight
environment. The starlight feature allows more details to be captured
and accurate color to be recognized at night or in scenes with limited
illumination.
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.
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 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
comes 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 ascene at the same time to provide usable video.
Advanced 3DNR
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.
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 –40 °C to +60 °C (–40 °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 4 KV lightning rating provides protection against the camera and its structure from the effects of
lightning.
