Dahua DH-HAC-HFW2501T-Z-A-DP: Pro series

System overview Experience 5 megapixel video with the simplicity of reusing existing coaxial infrastructure. The 5MP starlight HDCVI camera presents a high quality image with rich details even under extreme low-light conditions. The camera also features broadcast-quality audio to provide enhanced supplementary evidence collection. It offers various motorized/fixed lens models with 120dB true WDR and HD/SD switchable output. The higher resolution and starlight feature makes the 5MP HDCVI camera an ideal choice for mid to large-size businesses and projects where both highly reliable surveillance and construction flexibility are needed. Functions 4 signals over 1 coaxial cableHDCVI 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 transmissionHDCVI technology guarantees real-time transmission at long distance without any loss. It supports up to 700m transmission for 5MP HD video via coaxial cable, and up to 300m via UTP cable. **Actual results verified by real-scene testing in Dahua's test laboratory. SimplicityHDCVI technology inherits the born feature of simplicity from traditional analogue surveillance system, making itself a best choice for investment protection. HDCVI system can seamlessly upgrade the traditional analogue system without replacing existing coaxial cabling. The plug and play approach enables full HD video surveillance without the hassle of configuring a network. StarlightWith 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 recognised at night or in scenes with limited illumination. Broadcast-quality audioAudio 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. Multiple-formatsThe camera supports multiple video formats including HDCVI, CVBS, and other two common HD analogue formats in the market. A DIP switch located on the cable allows you to quickly toggle formats, further simplifying installationand debugging. This feature makes the camera compatible with not only XVRs, but also most existing HD/SD DVRs. Wide Dynamic RangeEmbedded with industry leading wide dynamic range (WDR) technology, vivid pictures are achieved even in the most intense contrast lighting conditions. True WDR (120dB) optimises both the bright and dark areas of a scene at the same time to provide usable video. Advanced 3DNR3DNR 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. ProtectionThe 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.

Dahua 1080p 1200-Lite-series HDCVI cameras and S2-series tri-brid DVRs

Dahua Technology, a world-leading manufacturer and supplier of video surveillance products headquartered in Hangzhou, China introduces a new 1080p HDCVI solution with more affordable price, which consists of 1080p 1200-Lite-series HDCVI cameras and S2-series tri-brid DVRs. The camera 1200-Lite-series includes IR-bullets and dome cameras, fixed and vari-focal lens are optional. The camera adopts powerful chipset, incorporating advanced sensor and ISP, which not only provides outstanding image quality with vivid colour and abundant details, but also offers a wider angle of view. Moreover, the in-house TX chipset is embedded in the ISP, making the camera quite compact. The camera adopts smart IR technology, along with photoresister, making day/night switch more accurate; what worth a mention is their superb noise reduction ability, which can not only save HDD storage capacity, but also help deliver a benefit of rendering brilliant visual effect even under low illumination, which is suitable for applications such as underground parking lot or anywhere in dim-light surroundings. “There was something hovering in my mind during product planning phase,” said John Li, HDCVI Product Manager at Dahua Technology. “At that time, what I was thinking was how to perfectly leverage performance and price, for example, we were keen to present very competitive 1080p HDCVI camera, satisfying HD surveillance with basic functions acquired. Most of all, the product should stay with a very friendly price and 1200-lite-series is the answer.” In addition to the HDCVI cameras, Dahua also presents tri-brid HDCVI S2-seies DVRs (HCVR S2 series). “We have indeed introduced some HCVRs before, but what makes S2 different is that this series is ready to replace all the conventional DVRs,” said Jason Zhong, Product Manager at Dahua Technology. “S2 has the best colour reproduction than ever.” Moreover, thanks to the enhanced ultra UTP EQ function, the S2-series is able to support even longer transmission distance, for example, 1,100 meters for 720p with clear images and 800 meters for 1080p; meanwhile, this series supports 4G/Wi-Fi, making transmission more smooth and faster.
