Dahua Technology Lite HAC-HDW1800M telecamera di sicurezza dome IP telecamera di sorveglianza esterno 3840 x 2160 pixel soffitto

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.

Multiple-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.

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.

Smart IR
The camera is designed with microcrystalline LED 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 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.

4K Real-time Image Display
Used together with 4K Real-time XVR, the camera can output 4K realtime video stream with clear details and no lag or smear.

How to use

Install the camera on a suitable ceiling surface using appropriate mounting hardware and ensure the wired connection is routed to a compatible network video recorder or PoE switch as required by your system. Position and secure the dome, then adjust rotation and tilt to cover the intended area. Configure the camera settings through the supporting Dahua interface or compatible NVR to set resolution, frame rate, and white balance (auto or manual). Verify the detection distance and image framing at ground level or typical object locations and make final adjustments as necessary.

Recommendations

For reliable outdoor performance, mount the camera under an overhang where possible to reduce direct exposure to precipitation. Use a stable wired network connection and, if applicable, a compatible Dahua recorder to take advantage of full-resolution recording at 30 fps. Adjust white balance to manual settings in mixed lighting environments for consistent colour reproduction.
