Hanwha Techwin brings super high resolution 8K camera to market
22 April 2020
SECURITY PERSONNEL responsible for the safety of visitors at airports, sports stadiums and other large-scale open environments where there's a high risk of terrorist activity can now rely on a high performance Wisenet video surveillance camera from Hanwha Techwin to help them detect and forensically analyse any suspicious activity.
“The super high resolution capabilities of the Wisenet TNB-9000 mean that large areas can be covered with sufficient pixel density to enable operators to digitally zoom in and view a sharp image of just a small part of the scene,” explained Uri Guterman (head of product and marketing at Hanwha Techwin Europe). “This ability to closely zoom in without losing any detail makes the Wisenet TNB-9000 ideal for those end user applications where installing multiple cameras may be impractical or otherwise cost prohibitive.”
The H.265 Wisenet TNB-9000, which makes use of a full size 43.3 mm CMOS sensor to capture true 8K images at 15 frames per second, is equipped with deep learning-based video analytics for the simultaneous detection and classification of various object types, including people, vehicles, faces and license plates.
The analytics capability is also able to ignore video noise, swaying trees, moving clouds and animals, all of which might normally be the cause of false alarms.
In addition to its deep learning capabilities, the Wisenet TNB-9000 boasts a wide range of built-in Intelligent Video Analytics, including tampering, loitering, directional detection, de-focus detection, virtual line, enter/exit, appear/disappear, audio detection and motion detection.
The cameras are also supplied with an audio analytics feature which recognises critical sounds such as raised voices, screams, broken glass, gunshots and explosions and generates an alert such that security personnel can react swiftly to any incidents.
Digital Wide Dynamic Range (DWDR) helps to accurately produce images in scenes that simultaneously contain very bright and very dark areas.
A micro SD/SDHC/SDXC memory slot allows up to 256 GB of video or data to be stored at the edge should there be disruption to the network. Video evidence, which might have been potentially lost, can be retrieved when the network connection has been restored.
There's a choice of H.265, H.264 or MJPEG compression, with the cameras’ bandwidth-friendly credentials enhanced by WiseSteam II, a complementary compression technology which dynamically controls encoding, duly balancing quality and compression according to movement in the image.
Bandwidth efficiency is improved by up to 99% compared to current H.264 technology when WiseStream II is combined with H.265 compression. As such, WiseStream II reduces the total cost of ownership of a video surveillance system by minimising the storage and bandwidth requirements of HD cameras.
Gigabit Ethernet and SFP fibre optics allow the transfer of up to 1,000 Mbps for high speed connectivity, while 12 V DC or HPoE negates the need to install separate power supplies. Support for Canon EF (Electro Focus) mount lenses provides a wide variety of options for focal length and aperture settings.
Guterman concluded: “The quality of the images captured by our highest resolution camera to date, together with its deep learning-based video analytics and other innovative features, provides security personnel with an extremely powerful tool to accurately detect any suspicious activity. As such, the introduction of the Wisenet TNB-9000 presents system integrators with an excellent opportunity to help their end user clients take their security to a higher level on a cost-effective basis.”
