Abstract: A computer-implemented method executed by one or more computer servers includes receiving a notification from a first communication device. The notification indicates an armed intruder within a first stationary geofence. The method further includes determining whether one or more of a first plurality of communication devices are within a second stationary geofence different than the first stationary geofence, and in response to the notification, providing an emergency alert to the communication device(s) determined to be within the second stationary geofence. Other example computer-implemented methods, communication devices including software applications, and systems for notifying one or more LEOs of an armed intruder by a premises personnel associated with a premises are also disclosed.

Abstract: A computer-implemented method executed by one or more computer servers includes receiving a notification from a communication device, determining whether one or more other communication devices are within a stationary geofence, and in response to the notification, sending an emergency alert to the other communication devices determined to be within the stationary geofence. The computer-implemented method may further include receiving an acknowledgement of the emergency alert from at least one of the other communication devices determined to be within the stationary geofence and/or sending data indicating an approximate location of the communication device and an associated tolerance of the approximate location. Other example computer-implemented methods, communication devices including software applications, and systems are also disclosed.
