As more businesses purchase advanced electronic security systems to protect their property, more guards are being assigned to stations where they monitor perimeter security, environmental functions, communications, and other systems. In many cases, these guards maintain radio contact with other guards patrolling on foot or in motor vehicles.

Guards who carry weapons must be licensed by the appropriate government authority, and some receive further certification as special police officers, which allows them to make limited types of arrests while on duty.
