FIR3X3516N/A

  This new product has the lightest weight with a compact size that rivals any commercially available fixed focal telephoto lens.Designed in a compact chassis that provide versatility in installations,applications,and system integration.Itcovers most commonly used focal length range of 35-105mm,with a constant maximum aperture of F/1.6 throughout the entire range.Optical zoom is best method for achieving the highest quality image magnification,but also convienient for setting up an ideal field of view for the area of interest.With threse features,this product will allow the users to build a totally new surveillance system that is ideal for their application.

(Note 1) The field of view have been calculated based on a sensor size of 10.88mm(V) x 8.7mm(H) (13.9mm diagonal). (VGA 17.0μm pixel pitch)
(Note 2) The max. object distance (detection) is a theoretical value calculated for seeing hμman sized objects based on Johnson's criteria under theassumption that VGA-17μm pixel pitch sensor is used. It is not an actual measured value.
