Radio frequency security system and method for a building facility

摘要

A security system for a building facility where radio frequency tamper-indicating devices are placed in the area of the facility to detect movement and/or relative movement of components under circumstances where such movement may indicate a security risk. One example is where there are ceiling tiles in a false ceiling which may be moved during a covert entry. An RF damage indicating device is placed at juncture locations of the tiles and tendrils of the tamper-indicating devices are positioned so that movement of one of the tiles will break the tendril and cause an alarm signal to be given. In other arrangements, tamper-indicating devices could be attached to security-sensitive objects, containers for the same, and building-related components so that movement of these security-sensitive objects would also trigger an alarm.
