Dahua’s 4K fisheye for coaxial infrastructure is a world first
Dahua Technology USA has created the the world’s first 4K fisheye for coaxial infrastructure, while expanding its portfolio with five new fisheye surveillance cameras. Fisheye technology provides exceptional detail, which is ideal for surveillance and applications that require broad coverage.
Dahua’s proprietary HD-over-coax technology is even more innovative, with the 4MP Pro Series HDCVI fisheye (A42AR2) and the 4K Ultra Series HDCVI fisheye (A83AR6).
HDCVI allows for transmission of HD and UHD images over coaxial cabling at distances of up to 1640 feet, thereby providing 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.
“Fisheye cameras allow for exceptional situational awareness,” remarked Jennifer Hackenburg, senior product marketing manager at Dahua Technology USA. “Advanced technology is alleviating previous limitations on clarity throughout the entire image.”
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.
