THERE ARE ELECTRONIC burglar alarms for houses, businesses, and cars, so why not for laptop computers? That's the idea behind Defcon 1, says maker Port Inc. in Norwalk, Conn. The $50 device for portable PCs combines a locking cable, a motion detector, and an alarm to help prevent laptop theft--which Port says reached more than 208,000 cases last year.
Defcon 1 comes with a retractable five-foot cable that can be locked to a special security slot designed into many current laptops or looped through a portable's carrying handle. The cable, which can be used independently of the alarm, secures the machine to less mobile equipment or furniture.
Once set, the battery-powered motion detector will trigger a 110-decibel alarm--louder than most common household smoke-detector alarms--if the PC is tilted or shaken or if its cable is cut. The 6.2-ounce device is available directly from the manufacturer or through computer dealers including Entex Computer Services and Ameridata.
