  Thermal camera range
  Hanwha Techwin Europe has added to its Wisenet T Thermal camera range three radiometric thermal models. Each has a temperature measurement feature.
  The Wisenet TNO-4030TR, TNO-4040TR and TNO-4041TR are able to detect if the air temperature is higher or lower than set parameters, such as above or below 40 degrees C. They have been designed to monitor areas which are vulnerable to fires, such as oil and chemical or construction sites, and forests, besides recycling and waste management centres which face spontaneous combustion. The cameras are also for monitoring poultry and livestock farms to detect temperature changes which could foster disease.
  The TNO-4030TR comes with a 13mm lens and has a maximum range of 1,173m for vehicle detection; while the TNO-4041TR, designed for mounting onto a PTZ unit, and the TNO-4040TR, have a 19mm lens and a maximum range of 1,714m.
  As is the case with other Wisenet T Thermal cameras, these three new models are able to capture images at up to 640 x 480 resolution and are designed to detect objects and people in difficult conditions such as through smoke, snow, heavy rain and fog, which traditional video surveillance cameras may not be able to do. They also offer a solution for projects where there are concerns about light pollution.
  The TNO-4030TR, TNO-4040TR and TNO-4041TR offer audio analysis to recognise critical sounds such as gunshots, explosions, screams and broken glass. Also featured are temperature change, shock, object/people direction, loitering and camera tampering detection.
  Built-in Gyro sensors offer stabilisation which comes into effect when a camera is disturbed by wind or vibrations, resulting in more stable images. The products come with a choice of H.265, H.264 or MJPEG compression; and 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 99pc it's claimed compared to H.264 when WiseStream II is combined with H.265 compression.
  熱成像攝像機
  Hanwha Techwin歐洲部已在其Wisenet T 熱成像攝相機系列中增加了三種熱輻射型號,且每種都有溫度測量功能。
  Wisenet TNO-4030TR,TNO-4040TR和TNO-4041TR型能夠檢測空氣溫度是高于還是低于設定參數,例如高于或低于40攝氏度。它們設計用于監測易受火災影響的區域除了回收和面臨自燃的廢物管理中心外,還有石油,化工或建筑工地,森林等。這些攝像機還用于監測家禽和養殖場,以檢測可能助長疾病的溫度變化。
  TNO-4030TR配備13mm鏡頭,車輛檢測最大范圍為1,173米; TNO-4041TR設計用于安裝在PTZ單元上,而TNO-4040TR則采用19mm鏡頭,最大范圍為1,714m。
  與其他Wisenet T Thermal攝相機一樣,這三款新型號能夠以高達640 x 480的分辨率捕捉圖像,旨在檢測困難條件下的物體和人,如煙霧,雪,大雨和霧環境下,傳統的視頻監控攝像機可能無法做到。他們還為那些擔心光污染的項目提供解決方案。
  TNO-4030TR,TNO-4040TR和TNO-4041TR可提供音頻分析,以識別槍聲,爆炸,尖叫聲和碎玻璃等重要聲音。還有溫度變化,震動,物體/人物運動方向,游蕩和攝像機篡改檢測功能。
  內置陀螺儀傳感器提供穩定性,當攝像機受到風或振動的干擾時生效,從而產生更穩定的圖像。產品可選擇H.265,H.264或MJPEG壓縮和WiseStream II,一種互補壓縮技術,可根據圖像中的移動動態控制編碼,平衡圖像的質量和壓縮。當WiseStream II與H.265壓縮相結合時,與H.264相比,它所宣稱的帶寬效率提高了多達99pc。
