Security guards and patrol services provide an essential layer of protection for businesses, homes, and other properties. These professionals are trained to detect suspicious activity, respond to emergencies, enforce laws, and protect people and property. Security guards can be armed or unarmed depending on the situation. They may patrol a certain area on foot or in a vehicle, monitor security cameras, conduct searches of visitors or employees entering a building, write reports about their activities and observations, and provide customer service. Patrol services can also include responding to alarms triggered by motion sensors or other devices. Additionally, they may provide additional services, such as escorting individuals from one location to another or providing first aid in the event of an emergency.
