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.
