Overload and Fuzzy Alarms
December 15, 2003
Today’s security command and control (C&C) centers run the risk of overwhelming monitoring personnel with too much data. Information pours in from exterior perimeter protection; heating, ventilation and air conditioning; fire alarms; elevator status; vehicle tracking; communications; visitor management; mustering; and site-specific systems such as asset control and asset tracking. The potential for fuzzy alarms increases. A fuzzy alarm, such as a fence sensor that could be triggered by several non-threatening stimuli, requires dispatchers to decide whether to send security personnel to respond to the alarm. According to Bill McGinty of Johnson Controls Security Solutions of Milwaukee, Wis., some techniques help maximize dispatch and response personnel. These include: filtering, automating, combining, prioritizing and presentation.
