The Wisenet TNM-3620TDY is a bi-spectrum, multi-channel device which incorporates a QVGA-class thermal imaging camera and a 2-megapixel video surveillance camera. As such, it is able to detect heat and measure temperature with a very high degree of accuracy, whilst 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 10 people in real time at a distance of up to 3m, with operators able to choose to view either the captured thermal images or standard high-definition video images.
According to Hanwha Techwin, the TNM-3620TDY is compliant with a series of device technical standards for the safety and essential performance of medical electrical equipment, which has been 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 is in progress.
In normal radiometric mode, the thermal imaging camera with a high degree of accuracy detects and measures changes in temperature within -20⁰C to 130°C range, with users 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 is 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 and utilities, is faulty.
In addition, a spot detection feature enables operators, via a web viewer, to click on any pixel within an image to obtain a measurement of the temperature of the area covered by that pixel. The camera 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.
