Security officers are not required to make arrests (but have the authority to make a citizen's arrest) or otherwise act as an agent of law enforcement at the request of a police officer, sheriff, and others. Security personnel may also perform access control at building entrances and vehicle gates. They ensure that employees and visitors display proper passes or identification before entering the facility. Security officers are often called upon to respond to minor emergencies (lost persons, lockouts, dead vehicle batteries, etc.) and to assist in serious emergencies by guiding emergency responders to the scene of the incident, helping to redirect foot traffic to safe locations, and by documenting events on incident reports.
Patrolling is usually a large part of a security officer's duties. Often these patrols are logged by use of a guard tour patrol system, which require regular patrols. Onsite Security Guards are an affordable, proven way to ensure the top level of protection available.
