TNM-3620TDY是一種雙頻譜，多通道設備，具有一個QVGA級熱成像攝像頭和一個2百萬像素視頻監控攝像頭。這樣，它可以檢測熱量，同時提供對其視野內人員的視覺驗證。

　　Temperature detection thermal camera

　　The dual purpose Wisenet TNM-3620TDY from Hanwha Techwin Europe comes with QVGA thermal imaging and high-definition cameras, for COVID-19-related work. The TNM-3620TDY is a bi-spectrum, multi-channel device with a QVGA-class thermal imaging camera and a 2-megapixel video surveillance camera. As such, it can detect heat while providing visual verification of people within its field of view.

　　In body temperature mode, the thermal imaging camera can to estimate a person’s temperature within a range of 30 to 45 degrees C, with +/-0.5 degrees C accuracy. When supported by black body technology, the accuracy increases to +/-0.3 degrees C, allowing the product to provide a strong indication that a person may have a fever, the product developers say.

　　Offering support for Deep Learning AI-based face detection, the device can measure the temperatures of up to ten people in real time at a distance of up to 3m. Operators can choose to view either the captured thermal images or standard high-definition video images.

　　The product is compliant with a series of device technical standards for the safety and essential performance of medical electrical equipment, as published by the International Electrotechnical Commission (IEC). 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 minus 20 degrees C to 130 degrees 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 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. 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 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 per cent it is claimed, compared to current H.264 technology when WiseStream, which is unique to Wisenet cameras, is combined with H.265 compression. Other features include:

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

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

　　– PoE+ (IEEE802.3at) and 12VDC.

　　Uri Guterman, Head of Product and Marketing for Hanwha Techwin Europe said: “Regretfully, in terms of the reputation of the video surveillance industry, some so called ‘fever screening’ solutions devised by other manufacturers, have attracted negative publicity. This is because they have been oversold in terms of what they are capable of delivering.

　　溫度檢測熱感攝像機

　　來自Hanwha Techwin公司歐洲公司的兩用途的Wisenet TNM-3620TDY型、具有QVGA分辨率的高清熱成像攝像機，可被用于與COVID-19相關的排查檢測工作。TNM-3620TDY是一種雙頻譜，多通道設備，具有一個QVGA級熱成像攝像頭和一個2百萬像素視頻監控攝像頭。這樣，它可以檢測熱量，同時提供對其視野內人員的視覺驗證。

　　在測溫模式下，熱感攝像機可以以+/- 0.5攝氏度的精度估算30到45攝氏度范圍內的人的溫度。產品開發人員說，當得到黑體技術的支持時，其準確度將提高到+/- 0.3攝氏度，從而使該產品能夠更好地檢測出有發燒的跡象人員。

　　該設備支持基于深度學習AI的面部檢測，可以在3m的距離內實時測量多達十個人的體溫。操作員可以選擇查看捕獲的熱圖像或標準高清視頻圖像。

　　該產品符合國際電工委員會(IEC)發布的有關醫療電氣設備安全性和基本性能的一系列設備技術標準。Hanwha Techwin已完成FDA設施注冊流程，并且正在就FDA 510(k)許可進行TNM-3620TDY的設備注冊。

　　在常規輻射測量模式下，高精度的熱成像攝像機可檢測和測量負20攝氏度至130攝氏度范圍內的溫度變化，用戶可以設置檢測區域以覆蓋攝像機領域內的特定關注區域看法。當在回收，廢物管理和垃圾填埋式設施中可能發生自燃的情況下發生火災威脅時，它可以提供了一種生成警報的工具。檢測到的溫度變化也以對工廠、加工廠、冷庫和公用設施中的機械故障發出警報。點檢測功能使操作員可以通過Web查看器單擊圖像中的任何像素，以獲得該像素所覆蓋區域的溫度測量值。

　　TNM-3620TDY支持H.265，H.264和MJPEG壓縮格式，以及WiseStream II，WiseStream II是一種互補的壓縮技術，可以根據圖像中的運動動態控制編碼，平衡質量和壓縮。與當前的H.264技術相比，Wisenet攝像機獨有的WiseStream與H.265壓縮相結合，帶寬效率提高了75%。其他功能包括：

　　– 具有一組智能視頻分析功的2百萬像素的視頻監控攝像機能，其中包括方向檢測，運動檢測，進入/退出，虛擬線路，音頻檢測和攝像機篡改檢測。

　　– TNM-3620TDY帶有Micro SD / SDHC / SDXC插槽，如果網絡中斷，最多可以在邊緣存儲256GB的視頻或數據。恢復網絡連接后，可以檢索可能丟失的視頻證據。

　　– PoE +(IEEE802.3at)和12VDC。
