Private Security Supervisor is responsible for overseeing security guards and operations in a gated community. The role serves as a critical link between frontline guards and management. 

A private security guard ensures property/personnel safety through patrols, access control (checking visitors/staff), surveillance monitoring (CCTV), and swift emergency response (alarms, incidents), requiring vigilance, discipline, good communication, and detailed report writing, acting as a visible deterrent to crime and maintaining order with professionalism.
