This paper describes the design and preliminary test results of a 360-degree scanning, multispectral intrusion detection sensor. This moderate-resolution, panoramic imaging sensor is intended for exterior use at ranges from 50 to 1500 meters. This Advanced Exterior Sensor (AES) uses three sensing technologies (infrared, visible, and radar), separate track processors and sensor fusion to provide low false-alarm intrusion detection, tracking, and immediate visual assessment. The images from the infrared and visible detector sets and the radar range data are updated as the sensors rotate about once per second. The radar provides range data with onemeter resolution. This sensor has been designed for low-cost, easy use and rapid deployment to cover wide areas beyond, or in place of, typical perimeters, and tactical applications around fixed or temporary high-value assets. A prototype AES has been developed and preliminary test results are presented. This sensor represents a growing trend to use low-cost thermal imaging sensors, combined with other devices and advanced processing, for protection of U.S. military forces and other national assets.

--The installation of a new intrusion detection system (IDS) is, of course, expected to improve site security. However, depending upon the way the system is used, it can, over time, actually degrade security. Proper use, control, and maintenance of the IDS is critical if site security is to be maintained. This paper discusses several operational issues that should be addressed in order to use an IDS effectively. Several anecdotes from the author's experience are given to illustrate proper and improper use of an IDS. Improper operational use of an IDS can render it ineffective. Applying these tips can help keep the IDS operating at peak performance.Background

-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.
