Cell Phone Detector
A solution to the growing problem of contraband cell phones in the law enforcement field, Manta Ray from Berkeley Varitronics Systems (BVS) is a detection device with a close range security scanner to pick up on concealed mobile phones. Designed to sense gadgets even when they are on, off or without batteries, the system works to scan specific components common to all cell phones — not just metal — reducing false alarms, according to the company. The detector works with LCD and standard removable nine-volt battery power.
