Dahua Technology Dahua kamera HAC-HDW2802T-A-0280B

System Overview\nExperience 4K video surveillance with the simplicity of reusing existing\ncoaxial infrastructure. The 4K HDCVI camera adopts a powerful Dahua\nISP and advanced 1/2" image sensor, which provides superior high quality\nimages. It also supports Starlight and 120dB true WDR for a clear image\nin poor lighting conditions. In addition, the camera features broadcastquality audio to provide enhanced supplementary evidence collection.\nUltra--high definition and a complete set of features makes the 4K HDCVI\ncamera an ideal choice for mid to large-size businesses and projects\nwhere both highly reliable surveillance and construction flexibility are\ndemanded.\n\n4 Signals over 1 Coaxial Cable\nHDCVI technology supports 4 signals to be transmitted over 1 coaxial\ncable simultaneously, i.e. video, audio*, data and power. Dual-way data\ntransmission allows the HDCVI camera to interact with the HCVR, such as\nsending control signal or triggering alarm. Moreover, HDCVI technology\nsupports PoC for construction flexibility.\n\nLong Distance Transmission\nHDCVI technology guarantees real-time transmission at long distance\nwithout any loss. It supports up to 700m transmission for 4K and 4MP HD\nvideo via coaxial cable, and up to 300m via UTP cable.\n\nSimplicity\nHDCVI technology inherits the born feature of simplicity from traditional\nanalog surveillance system, making itself a best choice for investment\nprotection. HDCVI system can seamlessly upgrade the traditional analog system without replacing existing coaxial cabling. The plug and\nplay approach enables full HD video surveillance without the hassle of\nconfiguring a network. \n\nStarlight\nWith the adoption of large sized high performance sensor, the camera is\nable to provide incomparable performance even under extreme lowlight\nenvironment. The starlight feature allows more details to be captured\nand accurate color to be recognized at night or in scenes with limited\nillumination.\n\nBroadcast-quality Audio\nAudio information is used as supplementary evidence in video surveillance\napplications. The HDCVI camera supports audio signal transmission over\ncoaxial cable. In addition, it adopts unique audio processing and transmission\ntechnology that best restores source audio and eliminates noise, guaranteeing the quality and effectiveness of collected audio information.\n\nMultiple-formats\nThe camera supports multiple video formats including HDCVI, CVBS, and\nother two common HD analog formats in the market. A DIP switch located on\nthe cable allows you to quickly toggle formats, further simplifying installation\nand debugging. This feature makes the camera compatible with not only\nXVRs, but also most existing HD/SD DVRs.\n\nWide Dynamic Range\nEmbedded with industry leading wide dynamic range (WDR) technology,\nvivid pictures are achieved even in the most intense contrast lighting\nconditions. True WDR (120dB) optimizes both the bright and dark areas of a\nscene at the same time to provide usable video.\n\nAdvanced 3DNR\n3DNR is noise reduction technology that detects and eliminates random\nnoises by comparing two sequential frames. Dahua’s advanced 3DNR technology allows remarkable noise reduction with little impact to sharpness,\nespecially under limited lighting condition. Besides, the advanced 3DNR\neffectively decreases the band width and saves the storage space.\n\nProtection\nThe camera's outstanding reliability is unsurpassed due to its rugged design.\nThe camera is protected against water and dust with IP67 ranking, making it\nsuitable for indoor or outdoor environments.\nSupporting ±30% input voltage tolerance, this camera suits even the most\nunstable power supply conditions. Its 4KV lightning rating provides protection against the camera and its structure from the effects of lightning.
