Building security refers to the measures and systems put in place to protect a structure and its occupants from unauthorized access, theft, or damage. This can include physical barriers like locks and fences, as well as electronic systems such as alarms and surveillance cameras. The goal is to create a safe environment for everyone inside the building. Effective building security also involves monitoring and controlling access points, such as doors and windows. Security personnel may be employed to oversee these areas, while policies and procedures are established to ensure that only authorized individuals can enter. Overall, building security is essential for maintaining safety and peace of mind.
