Disclosed are various embodiments for security systems for schools and similar structures. Various security devices may be monitored in a structure, such as a school, where at least one of the security devices includes a wall-mounted duress alarm, an electronic keypad, a radio-frequency identification (RFID) reader, a card access reader, a decibel meter, a smoke detector, or a mobile computing device. In response to a signal from one of the security devices being indicative of a breach having occurred in the structure, a predetermined breach policy may be automatically implemented that may include, for example, compartmentalizing a region of the structure by performing an automated closing of a door that separates the region of the structure from another region of the structure.

Systems and methods for deterring a person at a door using a door lock deter light are disclosed. One method of deterring an unknown person at a door includes sensing that a person approaches a door at which an exterior door lock interface including an illumination device is located. The method further includes determining whether the person is unknown and, in response to determining that the person is unknown, activating the illumination device on the exterior door lock interface to be in a deterrence state. Otherwise, the method further includes activating the illumination device to be in a non-deterrence state or maintaining the illumination device in a deactivated state.
