PTZ camera

by Mark Rowe

New from Hanwha Techwin is the Wisenet XNP-6550RH camera, designed for perimeter protection and large open area applications. Uri Guterman, Head of Product and Marketing for Hanwha Techwin Europe said: “The Hanwha Techwin product development team has ensured the 2 megapixel Wisenet XNP-6550RH is packed with features needed by security personnel to detect and observe suspicious activity over long distances in airports, car parks, industrial estates, stadia and city centre type environments.

“This is one of those cameras whose performance needs to be seen to be believed. The superior optical Defog feature built into the Wisenet XNP-6550RH is particularly impressive. Unique to Hanwha Techwin, de-fog involves the use of an optical low pass filter which is able to accept a higher light range in front of the camera’s image sensor in order to reduce the influence of fog. The ability to capture clear, sharp images in daytime conditions enables faces to be recognised up to 170 metres from the camera, also deserves a special mention.”

The XNP-6550RH, which is IP66 and IK10 rated for vandal-resistance and outdoor use in harsh sites, uses progressive scan technology to provide sharp edges on moving subjects and vehicles. It also comes with Wide Dynamic Range (WDR), which performs at up to 120dB to produce images in scenes that simultaneously contain very bright and very dark areas, while adaptive IR (infra-red) adjusts the angle of the camera’s IR LEDs to match the level of zoom.

An auto-tracking feature allows operators to monitor the movement of people or vehicles while remaining hands-free, to control other cameras. The XNP-6550RH is also able to ‘hand-over’ to cameras covering adjacent areas. Analytics include Tampering, Loitering, Directional Detection, Defocus Detection, Fog Detection, Virtual Line, Enter/Exit, Appear/Disappear, Audio Detection, Face Detection, Motion Detection and Sound Classification.

The XNP-6550RH allows multiple streams of images to be transmitted at a variety of frame rates and resolutions to any PC on the network or other devices such as smartphones and tablets. H.265 compression minimises latency, the makers add, for the manual tracking of moving objects. It also features WiseStream II, a complementary compression technology which dynamically controls encoding, balancing quality and compression according to movement in the image. Bandwidth efficiency is improved by up to 99 per cent it is claimed compared to current H.264 compression when WiseStream II is combined with H.265 compression.

The ability to store up to 256GB of data via 2 SD/SDHC/SDXC memory slots in the product ensures video is automatically recorded in the event of network disruption. Visit
