Hanwha Techwin launches temperature detection thermal camera

The dual-purpose Wisenet TNM-3620TDY camera from Hanwha Techwin is equipped with QVGA thermal imaging and HD capabilities designed to help businesses operate safely during the COVID-19 era.

The TNM-3620TDY is a bi-spectrum, multi-channel device which incorporates a QVGA-class thermal imaging camera and a 2 MP video surveillance camera. As such, it can detect heat and measure temperature with a very high degree of accuracy, while providing visual verification of people within its field of view.

In body temperature mode, the QVGA-class thermal imaging camera is able to estimate a person’s temperature within a range of 30⁰-45°C, with +/-0.5⁰C accuracy. When supported by black body technology, the accuracy increases to +/-0.3⁰C, allowing the TNM-3620TDY to provide a strong indication that a person may have a fever.

Offering support for deep learning AI-based face detection functionality, the TNM-3620TDY can measure the temperatures of up to ten individuals in real-time at a distance of up to 3 metres, with operators able to choose to view either the captured thermal images or standard HD video images.

IEC 60601 certification

The TNM-3620TDY is compliant with a series of device technical standards for the safety and essential performance of medical electrical equipment published by the International Electrotechnical Commission (IEC).

In addition, Hanwha Techwin has completed the FDA facility registration process and device registration for the TNM-3620TDY in respect of FDA 510(k) clearance which is in progress.

In normal radiometric mode and with a high degree of accuracy, the thermal imaging camera detects and measures changes in temperature within the -20⁰C to 130°C range. End users are able to set up detection zones to cover specific areas of interest within the camera’s field of view. This provides a powerful tool which generates alerts when there’s a threat of fire in recycling, waste management and landfill-type facilities where spontaneous combustion may occur. A detected change in temperature may also be a warning that machinery in factories, processing plants, cold stores or utilities is faulty.

In addition, a spot detection feature enables operators, via a web viewer, to click on any pixel within an image and obtain a measurement of the temperature of the area covered by that pixel.

WiseStream II technology

The TNM-3620TDY supports H.265, H.264 and MJPEG compression formats, as well as 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 75% when compared to current H.264 technology when WiseStream, which is unique to Wisenet cameras, is combined with H.265 compression.

The 2 MP video surveillance camera features a set of Intelligent Video Analytics which include directional detection, motion detection, enter/exit, virtual line, audio detection and camera tampering detection.

The TNM-3620TDY has a Micro SD/SDHC/SDXC slot which allows up to 256 GB of video or data to be stored at the edge should there be any disruption to the network. Video evidence, which potentially might have been lost, can therefore be retrieved when the network connection has been restored.

Capability to deliver

“Regretfully, some so-called ‘fever screening’ solutions devised by other manufacturers have attracted negative publicity,” said Uri Guterman, head of product and marketing for Hanwha Techwin Europe. “In my view, this is because they’ve been oversold in terms of what they’re capable of delivering.”

He continued: “Although we’ve often been the first to market with new product developments and technologies, in this instance we’ve taken the time to develop the TNM-3620TDY and ensure that it’s fit for purpose. We highly value the trust our customers and business partners have in our ability to provide solutions which do not compromise on performance and quality. In this respect, they can be confident that this camera will meet, if not exceed, their expectations.”

In conclusion, Guterman stated: “The TNM-3620TDY is a great addition to our suite of COVID-related solutions, which includes face mask detection, occupancy monitoring and AI deep learning-based social distance measuring applications.”

Hanwha Techwin introduces Wisenet T network thermal positioning cameras

Hanwha Techwin has added two thermal positioning cameras to its Wisenet T range. The Wisenet TNU-4041T and TNU-4051T models, which are able to capture images at up to 640 x 480 resolution, are designed to detect objects and people in difficult environmental conditions such as through smoke, snow, heavy rain and fog, which traditional video surveillance cameras may not be able to do. They also offer an effective solution for projects where there are concerns about light pollution.

With a pan speed of 120° per second and a ground-to-sky view of -90° to 40°, the TNU-4041T and TNU-4051T provide a versatile solution for monitoring wide open areas. Both models, which have a robust aluminium die-cast exterior, incorporate a true day/night (ICR) camera and can be programmed to endlessly pan 360°. They also offer operators the flexibility to select from up to 255 pre-set positions which can be scheduled.

The TNU-4041T is equipped with a 19-mm lens and has a maximum range of 1,714 metres for vehicle detection, while the TNU-4051T has a 35-mm lens and a maximum range of 3,157 metres.

Both cameras are able to monitor areas such as construction sites and oil, gas and chemical facilities which may have a temperature range of between -50˚C and +130˚C.

A wide range of features ensures that the TNU-4041T and TNU-4051T are able to deliver optimised images in every situation.

*Built-in Gyro sensors which offer accurate stabilisation that come into effect when a camera is disturbed by wind or vibrations, resulting in more stable images

*A ‘Hallway View’ feature provides a highly effective way in which to monitor narrow vertical areas such as corridors, tunnels and aisles, with the added bonus of minimising bandwidth and video storage requirements

*Analytics: The Wisenet TNU-4041T and TNU-4051T are equipped with audio analysis functionality which recognise critical sounds such as gunshots, explosions, screams and broken glass. Additional features include temperature change, shock, object/people direction, loitering and camera tampering detection

*WiseStream II is 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

*Support for H.264 and MJPEG compression and with an SD/SDHC/SDXC memory slot to ensure video is automatically recorded in the event of network disruption

Wavestore moves to integrate VMS with Paxton Net2 access control solution

Wavestore’s open platform Video Management Software (VMS) has been successfully integrated with Paxton’s Net2 access control system.

“In simple terms, the integration of Paxton Net2 with our VMS ensures that operators can instantly view live or recorded video to visually verify access control events,” said Enrico Bizzaro, head of integrations at Wavestore. “However, our respective engineering teams have worked closely together to achieve a level of functionality that delivers what we believe is the ‘Best of Breed’ solution for video, data and access control management.”

Net2 is a PC-based access control solution which offers centralised administration and control of sites from single to hundreds of doors and with up to 50,000 users. It can be easily customised to set up access privileges accommodating groups or individuals, while event reports may be generated with just a few clicks.

High level of technology interaction

“With an increasing number of access control and video surveillance systems being specified for the same projects, end users are understandably looking for a high level of interaction between the two technologies in order to provide a complete solution,” continued Bizzaro. “With this in mind, and working in partnership with Paxton, we’re able to offer a solution that provides two-way communication between the respective systems. This enables, for example, doors to be locked and unlocked remotely via Wavestore’s WaveView client application for seamless operation.”

Wavestore’s ‘any video, any format’ philosophy sees its VMS support all leading camera vendors across multiple camera technologies. These include very high megapixel, Ultra HD, 4K, HD, 360° fisheye, thermal and analogue cameras operating on H.264, MJPEG, MPEG-2, MPEG-4, MxPEG and JPEG200 video formats.

Wavestore can also integrate a host of other devices and sensors into its VMS, in turn allowing operators to simultaneously view, control and manage live video, recorded footage and integrated devices all from one screen and all at the same time to create a fully scalable and powerful total security solution.

Searching for access events

Other key features of the integration include the ability to easily search for access control events from any keyword, such as a person’s first name, surname or any other database credentials and instantly bring up video as well as perform back-up procedures using Wavestore’s three-click evidential export function from associated cameras.

There’s also the ability to view video of events in real time, such as ‘access denied’. Thanks to the Wavestore rules engine, end users are able to configure any number of customised actions in response to trigger events, such as when a person of interest presents a token to a specific door reader.
