An iris image acquisition system for expanding an iris recognition range is proposed. The iris image acquisition system for expanding the iris recognition range enables that a direction, zoom, and focusing of an iris photographing camera for photographing an iris image of a distant subject are controlled quickly and easily without high-level information processing and arithmetic processing.

System for acquisiting iris image for enlarging iris acquisition range

Disclosed herein is a method of detecting a vehicle speed. The method includes receiving a first vehicle image photographed by a camera at a first time; identifying an area occupied by the license plate from the first vehicle image and extracting a first number; receiving a second vehicle image photographed by the camera at a second time; identifying an area occupied by the license plate from the second vehicle image and extracting a second number; comparing the first number with the second number to determine whether the first number is equal to the second number; deciding an actual size of the number of plate; calculating a distance between the vehicle and the camera at first and second times; and calculating a vehicle speed.

Method of detecting speed using difference of distance between object and monitoring camera

A surveillance camera has waterproofing members detachably fitted into guide holes for focus control and zoom control. The camera has a lens controller waterproofing member, a focus controller and a zoom controller and includes a housing having a first guide hole and a second guide hole; a first rod fixing part combined with the focus controller outer surface and including a first extended part with a first rod fitting hole; a second rod fixing part combined with the outer surface of the zoom controller and including a second extended part with a second rod fitting hole; first and second waterproofing members sealing the first and second guide holes; a focus control rod fastened through the first waterproofing member; and a zoom control rod fastened through the second waterproofing member.
