Patrolling is usually done on foot, but if the property is large, guards may make their rounds by car or motor scooter. 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. As they make their rounds, guards check all doors and windows, see that no unauthorized persons remain after working hours, and ensure that fire extinguishers, alarms, sprinkler systems, furnaces and various electrical and plumbing systems are working properly. 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.
