360° Panoramic View
Equipped with a fisheye lens for 360° surround view (ceiling/floor mount) or 180° panoramic view (wall mount) and high resolution with no blind spot. The cameras are able to provide coverage of wide, open areas, such as airports, shopping malls, retail stores, offices, and more. So you will get a whole scene just with one fisheye camera.
Fisheye de-warping is a function to solve the serious distortion problem of the circular panoramic view and you will use up to 10-mode de-warping modes for different installations with our XVR or on the web. Every dewarping area is adjustable and optional as you want.
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 XVR, such as sending a control signal or triggering the alarm. Moreover, HDCVI technology supports PoC for construction flexibility.
Audio information is used as supplementary evidence in video surveillance applications. The HDCVI camera supports audio signal transmission over a 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.
Long Distance Transmission
HDCVI technology guarantees real-time transmission at a long distance without any loss. It supports up to 700m transmission for 5MP video via
coaxial cable and up to 300m via UTP cable. HDCVI technology inherits the born feature of simplicity from the traditional analog surveillance system, making itself the best choice for investment protection. HDCVI system can seamlessly upgrade the traditional analog system without replacing existing coaxial cabling. The plug-and-play approach provides full HD video surveillance without the hassle of configuring a network.
The camera is designed with microcrystalline LED IR illumination for the best lowlight performance. Smart IR is a technology to ensure brightness
uniformity in B/W images under low illumination. Dahua’s unique Smart IR adjusts to the intensity of the camera’s infrared LEDs to compensate for the distance of an object and prevents IR LEDs from overexposing images as the object comes closer to the camera.
Wide Dynamic Range
Embedded with industry-leading wide dynamic range (WDR) technology, vivid pictures are achieved even in the most intense contrast lighting con-
ditions. True WDR (120dB) optimizes both the bright and dark areas of a scene at the same time to provide usable video.
3DNR is a 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 on sharpness, especially under limited lighting conditions. Besides, the advanced
3DNR effectively decreases the band width and saves storage space.
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 outdoor lightning.
