An alert notification system and method for neighborhood, business, work location, community and other groups for broadcasting an alert message from one member of the group to the other members of the group. A member of the group who sees or hears of an alert condition, which may be criminal activity, suspicious character(s), animal running loose, natural or man-made disaster or the like, becomes an alert initiator by calling a centrally based alert processing device that, after verifying the caller is a member of a group, allows the caller to record an audible alert message describing the alert situation. The processing device then broadcasts the alert message to each member of the alert initiator's group or groups so the alert recipients may take appropriate action to protect lives and/or property. The alert processing device stores information regarding the caller and the message for later auditing and retrieval purposes.
