Unarmed security guards are responsible for monitoring a person or location, such as a retail store, a concert hall, or an office building. Their duties include crime prevention, monitoring surveillance videos, investigating suspicious activity, and reporting to a police officer if needed. The day-to-day work of a security guard depends on their role. A retail security guard’s goal is theft prevention and video monitoring, while a security guard at a concert hall may check bags for illegal devices. All unarmed security guards must be alert and professional. Patrons or customers will go to guards with concerns or questions, so excellent communication skills are also needed.
