Abstract : The performance of the Joint-Services Interior Intrusion Detection System (J-SIIDS) Passive Ultrasonic Sensor and Vibration Sensor in detecting an actual penetration through a structural wall is described. The passive sensor was designed to detect a penetration through hard building materials such as brick and concrete. The Vibration Sensor was designed to detect penetration through metal barriers. The evaluation verified the fact that the passive sensor and the Vibration Sensor are excellent detectors of penetration through hard building materials and steel barriers. (Author)
