  Single housing, two cameras

  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.

  雙目攝像機

  Hanwha Techwin公司為其Wisenet P系列攝像機推出了一個最新產品,該攝像機在一個外殼中包含了兩個視頻監控攝像機。兩通道多向Wisenet PNM-9000VD攝像機采用模塊化鏡頭設計和一套視頻分析功能,能夠使用兩個單獨的鏡頭捕獲相鄰區域的5MP圖像。根據所需的現場,可以從PNM-9000VD單獨購買3.7、4.6或7mm鏡頭模塊,這些模塊可以由安裝人員現場安裝。

  開發商表示,與2018年推出的2MP多向Wisenet PNM-7000VD一樣,多流PNM-9000VD降低了通常與安裝兩個單獨的攝像機相關的成本。該產品可以覆蓋例如L形區域,以監視走廊的兩個部分或建筑物的任一側。制造商表示這是一種解決方案,用于監視大型空地,例如停車場,購物中心和倉庫。

  PNM-9000VD即使有兩個攝像頭通道,也只需要一個IP地址。只需一個視頻管理軟件(VMS),這進一步降低了成本,同時支持以太網供電(PoE),從而消除了安裝電源電纜的需求。

  該產品支持H.264,H.265和MJPEG壓縮。但是,當H.265與WiseStream II結合使用時,帶寬效率比目前的H.264壓縮提高了99%,WiseStream II是一種互補的壓縮技術,可根據圖像的運動控制編碼,平衡視頻質量和壓縮。

  在這些功能中,真實寬動態范圍(WDR)的性能高達120dB,可從包含明亮和黑暗區域混合的場景中產生清晰的圖像,通常會導致圖像曝光過度或曝光不足。該產品具有鏡頭畸變校正和數字圖像穩定功能;以及面部,霧氣,虛線,出現/消失,游蕩和相機篡改檢測。走廊視圖選項使產品能夠生成9:16 x 3:4長寬比的圖像,以在高而狹窄的空間中工作,并具有最小化帶寬和視頻存儲的優點。每個通道都有兩個SD / SDHC / SDXC內存插槽,可以在網絡中斷的情況下自動錄制視頻。
