AD-HFW2802E-A, 4K Starlight HDCVI, IR Bullet Camera
AD-HFW2802E-A, 4K Starlight HDCVI, Experience 4K video surveillance with the simplicity of reusing existing, coaxial infrastructure.
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 transmission for 4K and 4MP HD, video via coaxial cable, and up to 300m via UTP cable.*
*Actual results verified by real-scene testing in Dahua’s test laboratory.
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.
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.
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.
The camera supports multiple video formats including HDCVI, CVBS, and, other two common HD analog formats in the market. A DIP switch located on, the cable allows you to quickly toggle formats, further, simplifying installation, and debugging. 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.
3DNR is noise reduction technology that detects and eliminates random noises by comparing two sequential frames. Dehua’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.
- 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 protection against the camera and its structure from the effects of lightning.
