Abstract

This research has developed an Integrated Computer Controlled Sensor Monitor (ICCSM) environment, to monitor and analyse alarm events associated with sensors, including an interface between a PC and a number of detectors. Such an environment will help the security industry analyse the factors causing false alarms at particular locations. The ICCSM environment monitors, and records, alarm data. Knowing exactly which sensor has been activated, and its location, is of paramount importance to the effective deployment of response forces and making the identification of causes of spurious alarms easier. The lCCSM environment is a combination of software and general purpose hardware, including a PC, an interface between a PC and a range of sensors, a Video Cassette Recorder (VCR), and a video camera. The software can process information from 64 different sensors, and output control information to a VCR. A database has been developed to record information from sensors such as detector location, date, and time of alarm. The ICCSM also generates written reports, allowing the user to fully examine the performance of a detection system. An intrusion, or the event triggering the sensor, is also captured on VCR for future verification. The ICCSM is a GUI based environment running under Microsoft Windows with menus and help facilities. It allows the user to simulate a range of conditions to adjust sensor sensitivity levels, providing the means to test the integrity of a detection system. A database is designed to add and delete the sensor information. The database is automatically updated as an intrusion is detected. The software operates in two modes, simulation and production. Simulation mode allows a security administrator to simulate possible alarm conditions to thoroughly test and fine tune a detection system. The production mode is for use in an operational environment and will operate autonomously for a maximum of 480 hours, thus previously unknown causes of false alarms may be determined.
