Feature:1. Motorized Lens: The lens is motorized (there are two high precision motors for motorized zoom and autofocus) and should be used with the driver PCB (not included).2. Lens Design: Adopts 5MegaPixel high resolution lens, with focal length of 6~22mm, 1/2.5 inch image format, optical glass and metal workmanship.3. IR Correction: The lens has an IR CUT function, which corrects the problem of color deviation during the day and improves the brightness at night.4. Important Parameter: 622mm focal length, D14 mount interface, low distortion, 0.3m minimum object dimension, 13.5mm Flange BFL, fixed aperture iris.5. Tough Shell: The lens is protected by premium aluminum alloy shell, which can be used in extreme environments, and better protect the lens.Specification:Item Type: Motorized Zoom LensMaterial: Aluminium alloy.Resolution: 5 MegaPixel Image Format: 1/2.5inFocal Length: 6~22mmAperture: F2.2Mount Interface: D14Field Angle (DxHxV)1/2.5 Short Focus: D 58, H 46.4, V 34.8 Telephoto: D 20.4, H 16.3, V 12.21/3 Short Focus: D 46.5, H 37.2, V 27.9 Telephoto: D 18, H 14.4, V 11.41/4 Short Focus: D 34.5, H 27.6, V 22.5 Telephoto: D 12.6, H 10.1, V 7.6Optical Distortion: -0.61~-15.6%(1/2.5in)CRA: 11.94 (short focus), 11.38 (telephoto)M.O.D.: Approx. 0.3m/11.81inDimension: 28x45.3mm/1.10x1.78inFlange BFL: Approx. 13.5mm/0.53inBFL: Approx. 6.4mm/0.25inMBF: Approx. 6.2mm/0.24inIR Correction: YesOperation:Iris: Fixed ApertureFocus: Autofocus (DC)Zoom: Auto Zoom (DC)Operating Temperature -20C~+60CPackage List:1 xLens
