制造商Hanwha Techwin表示,新的Wisenet PNM-9000QB摄像机模组专为ATM机、零售和其他欺诈和盗窃检测应用而设计。
  Camera module
  The new Wisenet PNM-9000QB camera module is designed for ATM, retail and other covert fraud and theft detection applications, say the manufacturers Hanwha Techwin.
  Remote camera heads comprise an image sensor camera with a fixed, pinhole or fisheye lens. As their name implies, they are designed to be installed remotely from the other components of a video surveillance camera and this means they can be discretely installed within an ATM and other tight spaces, or located neatly into a corner of a room or lift with the help of mounting brackets.
  With Hanwha Techwin’s Wisenet7 chipset, the PNM-9000QB camera module is able to simultaneously process images from the four remote head cameras. With less cable and network switches required, this makes the module more cost-effective than its single channel predecessor, the company says, as the time system integrators have to spend on-site is reduced. With a single IP connection, there is also a cost saving for end-users, as only one video management software (VMS) licence is required. Installed the other side of a wall to a module, the camera heads are isolated from the network. Although this is likely to be of benefit to most end-users, it will be of particular importance to banks who need to protect confidential customer data and prevent fraud.
  More protection comes with tamper detection which generates an alarm if someone covers, changes the angle or sprays paint on one of the head camera’s lens. The Tamper Detection feature is included in the module’s suite of Intelligent Video Analytics (IVA), as is defocus detection, motion detection and loitering detection.
  The Wisenet7 chipset in the PNM-9000QB features Hanwha Techwin’s latest ‘extreme’ Wide Dynamic Range (WDR). This performs at up to 120dB to enable each of the remote camera heads to capture 2-megapixel Full HD images at full frame rate even in contrasting light conditions as often seen at ATMs’ sites.
  With the support of WiseStream II, the bandwidth required to transmit images captured by a PNM-9000QB is reduced, the product firm says, which may negate the need for banks to incur the cost of upgrading network capacity when the camera is retro-fitted at an ATM location. This is because bandwidth efficiency is improved by up to 75 per cent it is claimed compared to H.264 compression, when WiseStream II is combined with H.265.
  Two Micro SD/SDHC/SDXC slots enable up to 512GB of video or data to be stored at the edge should communication between the PNM-9000QB and a Wisenet NVR be disrupted. The Automatic Recovery Back-up (ARB) feature built into the latest Wisenet NVRs, aids the transfer and storage of the images stored on the PNM-9000QB’s SD cards when the network connection is restored. This provides continuity of recording.
  Other features include:
  – Hallway View enables operators to monitor tall and narrow spaces such as shopping aisles;
  – Support for H.265, H.264 and MJPEG compression formats;
  – two alarm input/outputs (I/O);
  – Power over Ethernet (PoE+) which negates the need to install a power supply and separate cabling for the camera.

  摄像机模组
  制造商Hanwha Techwin表示,新的Wisenet PNM-9000QB摄像机模组专为ATM机、零售和其他欺诈和盗窃检测应用而设计。
  远程摄像机包括一个带有固定、针孔或鱼眼镜头的图像传感器摄像机。顾名思义,它们被设计为可以安装其他组件的远程视频监控摄像机,这意味着它们可以分散地安装在ATM和其他狭窄空间内,或者整齐地放置在房间的角落或通过支架进行安装。
  借助Hanwha Techwin的Wisenet7芯片组,PNM-9000QB摄像头模组能够同时处理来自四个远程摄像机的图像。该公司表示,由于需要较少的电缆和网络交换机,因此该模组比其单通道前任产品更具成本效益,因为减少了系统集成商在现场花费的时间。通过单个IP连接,终端用户也可以节省成本,因为仅需要一个视频管理软件(VMS)许可证。摄像头安装在墙的另一侧,与网络隔离。尽管这可能使大多数终端用户受益,但对于需要保护机密客户数据并防止欺诈的银行而言,这显得尤其重要。
  篡改检测提供了更大的保护,如果有人遮挡、改变角度或在头摄像头的一个镜头上喷漆,它将发出警报。篡改检测功能包含在模块的智能视频分析(IVA)套件中,包括散焦检测,运动检测和游荡检测。
  PNM-9000QB中的Wisenet7芯片组具有Hanwha Techwin的最新“极端”宽动态范围(WDR)。它的性能高达120dB,即使在ATM机现场经常看到的光线反差较大的情况下,也能使每个远程摄像头以全帧速捕获2百万像素全高清图像。
  该产品公司表示,在WiseStream II的支持下,减少了传输PNM-9000QB捕获的图像所需的带宽,这可能使银行无需为在ATM位置改装摄像机而承担升级网络容量的成本。这是因为当WiseStream II与H.265结合使用时,与H.264压缩相比,带宽效率提高了多达75%。
  如果PNM-9000QB和Wisenet NVR之间的通信中断,则两个Micro SD / SDHC / SDXC插槽可在边缘存储多达512GB的视频或数据。最新的Wisenet NVR内置了自动恢复备份(ARB)功能,当网络连接恢复时,有助于传输和存储存储在PNM-9000QB SD卡上的图像。这提供了记录的连续性。
  其他功能包括:
  –“走廊视图”使操作员可以监视较高和狭窄的空间,例如购物通道;
  –支持H.265,H.264和MJPEG压缩格式;
  –两个警报输入/输出(I / O);
  -以太网供电(PoE +)标准,因而不需要为安装摄像机而独立布线。
