What is a Security Metal Detector?
A security metal detector is an electronic device that alerts the operator whenever metal objects pass within range of the device. There are many different types of metal detectors, from walk-through models to hand-held wands. Some systems combine more than one type of detector. A metal detector is often found at entrances of official city buildings, coliseums, airports and anywhere that screening for guns, knives or other weapons is appropriate. Though most people are likely familiar with the type of metal detector that is permanently installed, these devices are mobile and can also be rented. Prices range depending on the type and number of units required, and whether or not the metal detectors will be set up by the company supplying them. A walk-through metal detector is the most convenient screening device, as the operator can simply stand by and watch as each person passes through, one at a time. If the system detects metal it will sound an audible alarm or flash a red light. Belt
