  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.
  热成像摄像机
  Hanwha Techwin欧洲部已在其Wisenet T 热成像摄相机系列中增加了三种热辐射型号,且每种都有温度测量功能。
  Wisenet TNO-4030TR,TNO-4040TR和TNO-4041TR型能够检测空气温度是高于还是低于设定参数,例如高于或低于40摄氏度。它们设计用于监测易受火灾影响的区域除了回收和面临自燃的废物管理中心外,还有石油,化工或建筑工地,森林等。这些摄像机还用于监测家禽和养殖场,以检测可能助长疾病的温度变化。
  TNO-4030TR配备13mm镜头,车辆检测最大范围为1,173米; TNO-4041TR设计用于安装在PTZ单元上,而TNO-4040TR则采用19mm镜头,最大范围为1,714m。
  与其他Wisenet T Thermal摄相机一样,这三款新型号能够以高达640 x 480的分辨率捕捉图像,旨在检测困难条件下的物体和人,如烟雾,雪,大雨和雾环境下,传统的视频监控摄像机可能无法做到。他们还为那些担心光污染的项目提供解决方案。
  TNO-4030TR,TNO-4040TR和TNO-4041TR可提供音频分析,以识别枪声,爆炸,尖叫声和碎玻璃等重要声音。还有温度变化,震动,物体/人物运动方向,游荡和摄像机篡改检测功能。
  内置陀螺仪传感器提供稳定性,当摄像机受到风或振动的干扰时生效,从而产生更稳定的图像。产品可选择H.265,H.264或MJPEG压缩和WiseStream II,一种互补压缩技术,可根据图像中的移动动态控制编码,平衡图像的质量和压缩。当WiseStream II与H.265压缩相结合时,与H.264相比,它所宣称的带宽效率提高了多达99pc。
