Hanwha Techwin introduces Wisenet 5 MP Flateye IR dome cameras

by Brian Sims

The Wisenet 5 MP Flateye IR dome cameras from Hanwha Techwin are designed for high humidity environments and for where condensation might occur because of temperature differences. 

A key feature of the Wisenet QNE-8011R and QNE-8021R domes is that they each have a flat surface cover which is applied to the front of the lens instead of the dome cover. This reduces IR diffused reflection which is caused by moisture and, in the absence of a normal transparent dome cover, also removes the effect scratches can have on image clarity.

“These new H.265 models are intended to provide a robust and cost-effective solution for video surveillance projects where the end user client wishes to capture HD images in challenging environmental conditions, such as industrial or food processing plants,” explained Uri Guterman, head of product and marketing for Hanwha Techwin Europe. “Security installers will also benefit from having to spend less time on site as there’s no need to initially remove and then mount a dome cap during the installation process.”

The Wisenet QNE-8011R is equipped with a 2.8 mm fixed lens and the QNE-8021R has a 4.0 mm fixed lens, while both have built-in IR functionality which ensures objects can be recognised at night up to a distance of 20 metres.

As is the case with all cameras in the Wisenet Q Series, the new models are all true day/night (ICR) cameras and feature Lens Distortion Correction. They also benefit from enhanced Wide Dynamic Range which performs at up to 120 dB to produce clear images from scenes containing a challenging mix of bright and dark areas that normally results in overexposed or underexposed images. 

Intelligent video analytics

A new open platform chipset at the heart of the new domes provides the opportunity for some third party applications to run on-board the domes and enhanced intelligent video analytics – such as de-focus and tampering detection, as well as directional, intrusion, motion and enter/exit detection – are provided as standard.

Multiple streaming is supported with the choice of H.265, H.264 or MJPEG compression, while the new domes’ bandwidth friendly credentials are enhanced by WiseStream II, a complementary compression technology which dynamically controls encoding, 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.

Other key features

*Hallway View which provides a highly effective way in which to monitor narrow vertical areas such as shopping aisles and corridors. It enables cameras, which can generate images in the 9:16 and 3:4 aspect ratios, to work effectively in tall and narrow spaces with the added bonus of minimising bandwidth and video storage requirements

*MicroSD/SDHC/SDXC memory slot allows up to 128 GB of video or data to be stored at the edge

*Power over Ethernet support which negates the need to install separate power supplies and cabling for each dome

*Compliant with ONVIF, the global standardisation initiative for IP-based physical security products which seeks to improve the interoperability of different manufacturers’ devices operating simultaneously as part of a single system
