  PTZ camera
  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.
  Hanwha Techwin的新产品是Wisenet XNP-6550RH摄像机,专门设计应用于周界防护和大型开放区域。 Hanwha Techwin Europe产品和营销主管Uri Guterman表示:“Hanwha Techwin产品开发团队确保了200万像素的Wisenet XNP-6550RH具有安全员所需的远距离检测和观察机场、停车场,工业区,体育场和市中心类型环境下?#30446;?#30097;活动等功能,。
  “这是其中一款需要相信其性能的相机。 Wisenet XNP-6550RH内置的卓越光学除雾功能特别令人印象深刻。 Hanwha Techwin的独特之处在于,除雾涉及使用光学低通率滤光片,该滤光片能够在摄相机的图像传感器前接受更高的光线范围,以减少雾的影响。它能够在白天条件下拍摄清晰锐利的图像,使得能够在距离相机170米外识别出面部。”
  自动跟踪功能?#24066;?#25805;作员在保持双手解放的同时监控人员或车辆的移动,以控制其他相机。 XNP-6550RH还能够“传递?#22791;?#30422;在相邻区域的摄像机。分析功能包括篡改,游荡,定向检测,散焦检测,雾检测,虚拟线路,进入/退出,出现/消失,音频检测,人脸检测,运动检测和声音分类。
  XNP-6550RH?#24066;?#22810;种图像流以各种帧速率和分辨率传输到网络?#31995;?#20219;何PC或智能手机和平板电脑等其他设备。制造商补充道,H.265压缩可以最大限度地减少手动跟踪移动物体的延迟。它还具有WiseStream II,这是一种互补压缩技术,可根据图像中的移动动态控制编码,平衡图像质量和压缩。与WiseStream II与H.265压缩相结合的当前H.264压缩相比,它带宽效率提高了99%。
