The latest in the Wisenet P camera series by Hanwha Techwin offers two video surveillance cameras in a single housing. The two-channel multi-directional Wisenet PNM-9000VD camera, which features a modular lens design and a suite of video analytics, is able to capture 5MP images of adjacent areas with two separate lenses. Depending on the field of view required, 3.7, 4.6 or 7mm lens modules are available for purchase separately from the PNM-9000VD, and these can be fitted on site by the installer.

　　As with the 2MP multi-directional Wisenet PNM-7000VD launched in 2018, the multi-streaming PNM-9000VD reduces the costs which would normally be associated with installing two separate cameras, the developers say. The product can cover, for example, an L-shaped area to monitor two sections of a corridor or either side of a building. It's a solution the manufacturer says for monitoring large open spaces such as car parks, shopping centres and warehouses.

　　The PNM-9000VD only needs a single IP address even though it has two camera channels. With only one Video Management Software (VMS) license required, this further reduces the cost of ownership, as does Power over Ethernet (PoE) support, which negates the need to install power supply cabling.

　　The product supports H.264, H.265 and MJPEG compression. However, bandwidth efficiency is improved by up to 99 per cent it's claimed compared to current H.264 compression when H.265 is used with WiseStream II, a complementary compression technology which controls encoding, balancing quality and compression according to movement in the image.

　　Among the features, True Wide Dynamic Range (WDR) performs at up to 120dB to produce clear images from scenes which contain a mix of bright and dark areas which normally results in overexposed or underexposed images. The product has lens distortion correction and digital image stabilisation; and face, fog, virtual line, appear/disappear, loitering and camera tampering detection. Hallway view options enables the product to generate images in the 9:16 x 3:4 aspect ratio to work in tall and narrow spaces, with the bonus of minimising bandwidth and video storage. There are two SD/SDHC/SDXC memory slots for each channel enabling video to be automatically recorded in the event of network disruption.

　　Hanwha Techwin公司为其Wisenet P系列摄像机推出了一个最新产品，该摄像机在一个外壳中包含了两个视频监控摄像机。两通道多向Wisenet PNM-9000VD摄像机采用模块化镜头设计和一套视频分析功能，能够使用两个单独的镜头捕获相邻区域的5MP图像。根据所需的现场，可以从PNM-9000VD单独购买3.7、4.6或7mm镜头模块，这些模块可以由安装人员现场安装。

　　开发商表示，与2018年推出的2MP多向Wisenet PNM-7000VD一样，多流PNM-9000VD降低了通常与安装两个单独的摄像机相关的成本。该产品可以覆盖例如L形区域，以监视走廊的两个部分或建筑物的任一侧。制造商表示这是一种解决方案，用于监视大型空地，例如停车场，购物中心和仓库。

　　PNM-9000VD即使有两个摄像头通道，也只需要一个IP地址。只需一个视频管理软件（VMS），这进一步降低了成本，同时支持以太网供电（PoE），从而消除了安装电源电缆的需求。

　　该产品支持H.264，H.265和MJPEG压缩。但是，当H.265与WiseStream II结合使用时，带宽效率比目前的H.264压缩提高了99％，WiseStream II是一种互补的压缩技术，可根据图像的运动控制编码，平衡视频质量和压缩。

　　在这些功能中，真实宽动态范围（WDR）的性能高达120dB，可从包含明亮和黑暗区域混合的场景中产生清晰的图像，通常会导致图像曝光过度或曝光不足。该产品具有镜头畸变校正和数字图像稳定功能；以及面部，雾气，虚线，出现/消失，游荡和相机篡改检测。走廊视图选项使产品能够生成9:16 x 3：4长宽比的图像，以在高而狭窄的空间中工作，并具有最小化带宽和视频存储的优点。每个通道都有两个SD / SDHC / SDXC内存插槽，可以在网络中断的情况下自动录制视频。
