Dahua Technology USA, a leading manufacturer of video surveillance solutions proven the world over, has added five new fisheye cameras to their product portfolio, including the world’s first 4K fisheye for coaxial infrastructure. The latest in HD and UHD imaging combined with fisheye technology provides exceptional detail for applications that require broad coverage. Dahua’s proprietary HD-over-coax technology adds even more innovation to the mix, with the 4MP Pro Series HDCVI fisheye (A42AR2) and the 4K Ultra Series HDCVI fisheye (A83AR6). The 4K HDCVI fisheye is the first fisheye in the industry to use coaxial infrastructure.
HDCVI allows for transmission of HD and UHD images over coaxial cabling at distances of up to 1640 feet. This maximizes investment in legacy infrastructure by delivering forensic-level images without the need to rip and replace cabling. The 4K and 4MP HDCVI fisheye cameras are equipped with multiple edge dewarping modes and provide a 180° / 360° view that eliminates blind spots.
Dahua is also bringing three network fisheye cameras into the Ultra Series lineup: two 6MP options (N68BR4 and N68BR4V) and a 12MP model (NK8BR4). The N68BR4 model offers edge dewarping, while the N68BR4V model has client-side dewarping. The N68BR4V also incorporates Panomorph technology from ImmerVision Enables®, an industry leader in 360° solutions and applications. Its optics increase the pixels of the target image, improving the resolution of objects at the edge of the field of view.
Other benefits of the new network fisheye cameras are STARVIS sensors for superior low-light capability, true day/night IR cut filters for varying lighting conditions, and Intelligent Video System (IVS) analytics for more efficient monitoring. These cameras also feature Dahua’s innovative Smart H.265+ compression codec, which reduces bandwidth and storage requirements by up to 80% compared to standard H.264.
