A computer-implemented method executed by one or more computer servers, the method comprising:

• receiving a notification from a first communication device, the notification indicating an armed intruder within a first stationary geofence, said notification made in response to input from a first user;
• and
• determining whether said first communication device is within said first stationary geofence;
• wherein the notification is ignored if the first communication device is determined to be outside the first stationary geofence;
• and
• wherein the following additional steps are performed only if the first communication device is determined to be within the first stationary geofence:
• automatically determining whether one or more of a second plurality of communication devices are within a second stationary geofence different than the first stationary geofence;
• in response to the notification, automatically providing an emergency alert to one or more of the second plurality of communication devices the communication device(s) determined to be within the second stationary geofence;
• receiving an acknowledgement from at least one of the second plurality of communications devices in response to input from a second user;
• and
• automatically displaying information related to the notification on the device which sent the acknowledgement as soon as such information becomes available.
