Perimeter security has come a long way since the days of fortified castles and moat and drawbridges. It now encompasses sophisticated technology such as biometrics and underground sensors designed to deter, detect, delay and deny unauthorised access. Regardless of the size of the area to be protected – whether it’s a large airport or an office block – protecting a building or site involves putting up a series of barriers designed to completely deter, or at the very least, slow down the perpetrator.
