WiseNet P series camera

　　Hanwha Techwin (formerly Samsung Techwin) has launched three new Samsung Wisenet P 4K cameras. These come with H.265 compression and WiseStream, a complementary compression technology which the product company says dynamically controls encoding, balancing quality and compression according to movement in the image. As a result, the bandwidth and storage requirements of the 12MP resolution images captured by the Wisenet P cameras are significantly reduced and are similar to that normally used by lower resolution Full HD H.264 cameras, it is claimed.

　　When WiseStream is combined with H.265 compression, bandwidth efficiency can be improved by up to 75 per cent the makers say compared to current H.264 compression. These new Wisenet P cameras feature Digital Auto Tracking which during times of low activity, such as night, can be used to detect moving objects or people. The cameras also share features with Wisenet Q 2MP and 4MP cameras, such as IR illumination as standard and Defocus Detection which recognises when a camera is out of focus, as well as True Wide Dynamic Range, Hallway View and Lens Distortion Correction, to deliver optimised images in every situation.

　　The three models in the Wisenet P series are:

　　PNO-9080R: 4K IR Bullet camera

　　PND-9080R: 4K IR Dome camera

　　PNV-9080R: 4K Vandal resistant IR Dome camera.

　　WiseNet P系列摄像机

　　Hanwha Techwin（以前的Samsung Techwin公司）发布了三款新的Samsung Wisenet P 4K摄像机。这些摄像机具备H.265压缩和WiseStream技术，一个互补的压缩技术，根据图像中的移动来动态控制编码，平衡图像质量和压缩。因此，由Wisenet P摄像机捕获的1200万像素分辨率的图像的对于带宽和储存的需求有着显著的降低，效果类似于低分辨率的全高清H.264摄像机。

　　当WiseStream与H.265压缩技术想结合，与普通H.265压缩技术相比带宽效率最高可提升75%。这些新的Wisenet P摄像机在夜间这样低活动请况下将开启数字自动追踪功能来探测移动物体或人。该系列摄像机还与Wisenet Q 200万像素和400万像素摄像机共享功能，例如标准红外照明和离焦检测（当识别出摄像机失焦时），以及真实宽动态范围。走廊视角和镜头失真校正功能 可以保证摄像机在各种情况下都能提供优化的图像。
