  H.265 domes

  Hanwha Techwin's new WisenetFlateye IR dome cameras have been designed for high humidity sites and for where condensation might occur because of temperature differences.

  The main feature of the new H.265 domes, which are part of the Wisenet Q series, is that they each have a flat surface cover which is applied to the front of the lens instead of the dome cover. This reduces IR diffused reflection which is caused by moisture and in the absence of a normal transparent dome cover, also removes the effect scratches can have on image clarity.

  The 2 megapixel Wisenet QNE-6080RV and 4 megapixel QNE-7080RV domes have built-in infra-red, which ensures objects can be recognised at night up to a distance of 30 metres, while a 3.1x (3.2 - 10mm) motorisedvarifocal lens enables wide-angle monitoring. The new domes also come with defocus detection which generates an alert if the camera is out of focus and 'defogging' which makes corrections to blurry images which are captured in foggy conditions.

  The products feature Wide Dynamic Range (WDR), which performs at up to 150dB to produce images in scenes that contain very bright and very dark areas at once, and Lens Distortion Correction (LDC) which compensates for the image distortion that can occur with wide angle lenses. A Hallway View feature provides a way to monitor narrow vertical areas such as corridors, tunnels and aisles, that minimises bandwidth and video storage requirements, the makers add.

  H.265半球摄像机

  Hanwha Techwin公司的新型WisenetFlateye红外半球摄像机专为高湿和可能因温差而发生冷凝的场所而设计。

  作为Wisenet Q系列一部分的新型H.265半球摄像机的主要特点是它们每个都有一个平坦的表面覆盖应用于镜头的前面而不是圆顶盖。这减少了由湿气引起的IR漫反射,并且在没有普通透明圆顶盖的情况下,也消除了划痕对图像清晰度的影响。

  200万像素Wisenet QNE-6080RV和400万像素QNE-7080RV半球摄像机内置红外线,确保在夜间对目标的识别能够到达30米,而3.1x(3.2 -  10mm)电动变焦镜头可以实现广角监控。新的半球摄像机还带有散焦检测功能,如果相机失焦,则会产生警报,"雾化"功能可以校正在雾状条件下拍摄的模糊图像。

  这些产品具有宽动态范围(WDR),可在高达150dB的频率下在同?#26412;?#26377;非常明亮和非常暗的区域的场景中生成图像,以及镜头失真校正(LDC),可补偿宽幅可能出现的图像失真角度镜头。具该制造商补充,走廊视图功能提供了一种监控狭窄垂直区域(如走廊,隧道和过道)的方法,可最大限度地降低带宽和视频存储需求。
