RECElV MAR 1 5 19%The purpose of an intelligent alarm analysis system is to provide complete and manageable information to a central alarm station operator by applying alarm processing and fusion techniques to sensor information. This paper discusses the sensor fusion approach taken to perform intelligent alarm analysis for the Advanced Exterior Sensor (AES). The AES is an intrusion detection and assessment system designed for wide-area coverage, quick deployment, low falsehuisance alarm operation, and immediate visual assessment. It combines three sensor technologies (visible, infixed, and millimeter wave radar) collocated on a compact and portable remote sensor module. The remote sensor module rotates at a rate of I revolution per second to detect and track motion and provide assessment in a continuous 360" field-of-regard. Sensor hsion techniques are used to correlate and integrate the track data &om these three sensors into a single track for operator observation. Additional inputs to the fusion process include environmental data, knowledge of sensor performance under certain weather conditions, sensor priority, and recent operator feedback. A confidence value is assigned to the track as a result of the fusion process. This helps to reduce nuisance alarms and to increase operator confidence in the system while reducing the workload of the operator. IntroductionA typical central alarm station for a security environment is an integrated system of people, procedures, and equipment. An alarm communication and display system receives alarm signals fiom intrusion detection sensors and displays the information to a security operator for action. Although annunciator displays observed by the operator are easy to understand and maintain, they typically contain only a limited amount of information. Therefore, the operator must manually assess each alarm occurrence, which could be difficult, time consuming, and error-prone. The idea behind intelligent alarm analysis (IAA) is to preprocess data from the security sensors and present alarm information to the security operator in a manner that would provide concise and meaningful information and increase confidence in true alarm events while filtering out the necessity to assess nuisance and false alarms. One of the goals of the IAA Project at Sandia National Laboratories is to devise this preprocessing methodology using alarm processing and fusion techniques on available sensor data.Initial intelligent alarm analysis concepts were developed for the Advanced Exterior Sensor (AES), an intrusion detection and assessment system currently being developed at Sandia.

-Exciting new safeguards and security technologies are on the horizon, and some are even on the shelves today. Selftesting sensors, smart sensors, and intelligent alarm analyzers are all designed to provide useful information to the operator. However, today's current annunciator systems were not designed to accommodate these new technologies. New display technologies are also changing the look and feel of the annunciator of the future. Annunciator technology needs to "catch up" to these other security technologies. This paper presents the concept for a new, object-oriented approach to annunciator architecture design. The new architecture could accommodate simple, switch-closure devices as well as informationrich sensors and intelligent analyzers. In addition the architecture could allow other leading-edge interfaces to be easily integrated into the annunciator system. These technologies will reduce operator workload and aid the operator in making informed security decisions.
