Security guards are responsible for maintaining the safety of people and property in a specific area. These guards are usually trained for equipment such as alarms, cameras, motion sensors and radios to identify and respond to crimes, fires, medical emergencies and noise.
Security guards monitor and report suspicious or unusual activity to their employers or appropriate authorities; they investigate alarms and noises and remove intruders from property.
Education and training
In most states, you need to have a license as a security guard to work since many employers will train you.
A security guard can achieve a high position (if the employer uses a ranking system) or become a supervisor or security manager with additional experience.
Security guards normally provide security to armored cars, public buildings (colleges, universities, and government offices), private residences, commercial buildings (casinos, retail stores) or events (carnivals, concerts).
