***EVI－D31(P制)/EVI-D30(N制)是联接有高质量的1／3英寸CCD的彩色摄像机，它们有着***的全景拍摄和转动基础，有着理想的录像传送和总体监控装置。自动跟踪使摄像机区别于其它普通摄像机。当会议场景中的物体一有移动，摄像机自动跟随该移动物体，自动跟踪系统可自行跟踪和分析找出颜色与亮度与该物体相似的像素，还可利用底片和***的背光补偿系统来保证物体尽可能连续保持原有的亮度水平。移动探测方式探测运动是在两个被控制器限定场景的地区。当移动在一个窗口被探测到时，一种警报信号会被输出，能自动识别被摄物体，同时具有动态检测功能。具有上、下、左、右***功能的彩色摄像机，12倍光学变倍、高速自动聚焦镜头，可预置、***、变倍、聚焦、亮度等（在6个信道）EVI-D30EVI-D31VideoSignalNTSCPALImageSensor1/3"HyperHADColorCCDEffectivePixels768(H)X492(V)752(H)X585(V)H.Resolution460TVlines450TVlinesV.Resolution350TVlines400TVlinesLensX12PowerZoom,tof=5.4to64.8mm,F1.8toF2.7H.AngleofView4.3to48.8degreesShortestSubjectDist10mm(WIDEend),800mm(TELEend)Min.Illumination7lx(F1.8)IlluminationRange7to100,000lxAutoExposureAutoIris,AGCShutterSpeed1/60to1/10,000(VISCATMcontrol)1/50to1/10,000(VISCATMcontrol)GainAuto/Manual(VISCAcontrol)WhiteBalanceATW/OnePushHold,IndoorPreset,OutdoorPreset(VISCAcontrol)S/NRatiomorethan48dBPan/TiltHorizontal&plu***n;100degree(Maxspeed80degree/sec),Vertical&plu***n;25degree(Maxspeed50degree/sec)VideoOutputRCApinjack,1Vp-p,75ohmunbalancedSVideoOutput4pinminiDINAudioOutputRCApinjack(monaural),Ratedoutput327mV,Outputimpedancelessthan2.2kilohmsControlTerminalRS-232C,8pinminiDIN,9600bps,Data8bit,Stop1bitMicrophoneInputTerminalMinijack(monaural)(f3.5),Ratedinput0.775mVDC3Vforlowimpedancemicrophone,InputImpedancemorethan10k½PowerTerminalDCIN13.5V(***Junifiedpolaritytype)PowerRequirementsDC12to14VPowerC***umption11WOperatingTemperature0to40°CStorageTemperature-20to60°CDimensi***(W/H/D)Camera142x109x164mm,RemoteCommander56x26x210mmMassCamera1200g,RemoteCommander109gSuppliedAccessoriesACPowerAdapter,***cable,RemoteCommander,VelcroTape,OperatingInstruction)
