Dahua Technology Lite HAC-HDW1801T-Z-A security camera Dome IP security camera Outdoor 3840 x 2160 pixels Ceiling/wall

System Overview
Experience 4K video surveillance with the simplicity of reusing existing
coaxial infrastructure. The 4K HDCVI camera adopts a powerful Dahua
ISP and advanced 1/2.7" CMOS sensor, which provides superior high
quality images. In addition, the camera features broadcastquality audio
to provide enhanced supplementary evidence collection. Ultra-high
definition and a complete set of features makes the 4K HDCVI camera
an ideal choice for mid to large-size businesses and projects where both
highly reliable surveillance and construction flexibility are demanded.

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.

Long Distance Transmission
HDCVI technology guarantees real-time transmission at long distance
without any loss. It supports up to 700m transmission for 4K and 4MP
HD video via coaxial cable, and up to 300m via UTP cable.

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.

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.

Multi-formats
The camera supports multiple video formats including HDCVI, CVBS,
and other two common HD analog formats in the market. This feature
makes the camera compatible with not only XVRs, but also most existing
HD/SD DVRs.

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.

Advanced 3D NR
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.
Supporting ±30% input voltage tolerance, this camera suits even the
most unstable power supply conditions. Its 4KV lightning rating provides
protectionagainst the camera and its structure from the effects of
lightning.
