A new weatherproof dome camera from Speco Technologies of Amityville, New York, offers resolution of 540 lines and resistance to tampering. The HT-7247iHR uses a 9- to 22-millimeter auto-iris varifocal lens to produce sharp pictures. The snap-on Chameleon Cover converts the housing from standard dark gray to decorator white, and it can be painted any color to match its surroundings. The camera is wall and ceiling mountable and offers dual voltage (12 VDC/24 VAC) operation with line lock. The company’s Intensifier Technology amplifies and maximizes existing light to generate pictures in darkness where other cameras cannot. Also available is the HT-7246iHR model, which is equipped with a 2.8- to 11-millimeter lens.
