Wisenet P“Premium”摄像机系列的最新成员消除了在需要监视建筑物的两个相邻侧面时可能丢失视频证据的风险。
  Three-channel multi-directional camera
  The latest addition to the Wisenet P ‘Premium’ camera series removes the risk that video evidence might be missed when there is a need to monitor two adjacent sides of a building.
  With the middle camera sensor covering the blind spot between the areas being monitored by the other two sensors, the three-channel multi-directional Wisenet PNM-8082VT camera provides a way to ‘see around corners’ and offers an alternative to deploying three standard fixed cameras, says the manufacturer Hanwha Techwin Europe.
  Uri Guterman, Head of Product and Marketing for Hanwha Techwin Europe says: “Together with our existing two, four and five-channel multi-sensor cameras, the PNM-8082VT offers cost savings for both system integrators and end users. They all use less cable, conduit, mounting hardware and network switches, compared to that normally needed to install a greater number of standard cameras, and with just a single IP connection, only one VMS licence is required.”
  The product has IP66, IK10 and NEMA4X ratings for protection against water, dust and mechanical impact. The makers say it’s for outdoor applications; also for indoors, such as when there is a requirement to observe activity, for example at a ‘T’ shaped corridor.
  The camera’s middle sensor can be used to combat an intruder trying to attack or spray paint on the camera lens without video evidence of them being captured. A potential blind spot, which can occur when two standard cameras are pointing in different directions to cover two corner sides of a building, is avoided. This is because the product’s three directional monitoring ensures that regardless of which direction the intruder approaches, they will be on camera.
  With a removable infrared cut filter (ICR), each of the camera’s sensors offers true day/night camera functionality and is able to catch 2-megapixel high definition colour images when the lighting level is as low as 0.04 Lux. They also come with Hanwha Techwin proprietary ‘extreme’ Wide Dynamic Range (WDR) which, performing at up to 150dB, uses new Local Contrast Enhancement and Scene Analysis technologies to capture images from scenes containing a mix of bright and dark areas.
  The device’s 2 Micro SD/SDHC/SDXC slots enable up to 1,024GB of video or data to be stored at the edge should there be disruption to the network. Video of any incidents, which might have been lost, can therefore be retrieved when the network connection has been restored.
  Other features include:
  – Single IP connection with only one VMS license is required.
  – A single push of a button located at the back of the camera is all that is needed to automatically focus the camera.
  – Intelligent Video Analytics (IVA) includes defocus detection, directional detection, enter/exit, motion detection, virtual line and camera tampering detection.
  – Support for WiseStream II complementary compression, as well as H.265, H.264 and MJPEG compression formats. Bandwidth efficiency is improved by up to 75 per cent it is claimed, compared to current H.264 compression when WiseStream II is combined with H.265.
  – PoE+ which negates the need to install a power supply and separate cabling for the camera.

  三通道多向摄像机
  Wisenet P“Premium”摄像机系列的最新成员可以消除在需要监视两个相邻建筑物时可能丢失视频证据的风险。
  中间的摄像头传感器覆盖了由其他两个传感器监视的区域之间的盲点,因此三通道多向Wisenet PNM-8082VT摄像机提供了一种“四处查看”的方式,并提供了部署三个标准固定摄像机的替代方法。
  Hanwha Techwin欧洲公司产品与营销主管Uri Guterman表示:“与我们现有的二、四和五通道多传感器摄像机一起,PNM-8082VT可以为系统集成商和终端用户节省成本。与安装大量标准摄像机通常所需的电缆,导管,安装硬件和网络交换机相比,它们全部都使用更少的电缆,并且只需一个IP连接,仅需要一个VMS许可证。
  该产品具有IP66,IK10和NEMA4X防护等级,可防止水,灰尘和外力冲击。制造商表示它是用于户外应用,也适用于室内,例如当需要观察活动时,例如在“ T”形走廊上。
  摄像机的中间传感器可用于对付入侵者,可用于入侵者试图在摄像机镜头上进行喷漆或喷涂时,由于缺少视频证据而无法给他们定罪的情况。避免了潜在的盲点,当两个标准摄像机指向不同的方向以覆盖建筑物的两个角落时,可能会出现盲点。这是因为该产品的三个方向的监视功能可确保无论入侵者朝哪个方向靠近,它们都将位于摄像机的可视范围。
  借助可移动的红外截止滤光片(ICR),该摄像机的每个传感器都提供了真正的昼/夜摄像机功能,并且当照明水平低至0.04 Lux时,也可以捕获2百万像素的高清彩色图像。它们还配备了Hanwha Techwin专有的“极致”宽动态范围(WDR),其最高可达150dB的性能,它使用了新的局部对比度增强和场景分析技术,可以从包含明暗区域混合的场景中捕获清晰的图像。
  该设备的2个Micro SD / SDHC / SDXC插槽可以在网络中断的情况下在边缘存储多达1,024GB的视频或数据。恢复网络连接后,可以检索可能丢失的任何事件的视频。
  其他功能包括:
  –仅需要一个VMS许可证的单个IP连接。
  –只需按一下摄像机背面的按钮即可自动对焦摄像机。
  –智能视频分析(IVA)包括散焦检测,方向检测,进入/退出,运动检测,虚拟线和摄像机篡改检测。
  –支持WiseStream II互补压缩以及H.265,H.264和MJPEG压缩格式。当WiseStream II与H.265结合使用时,与当前的H.264压缩相比,带宽效率提高了多达75%。
  – PoE +,无需为摄像机安装电源和单独的电缆。
