Intrusion Detection

An intrusion detection system is intended to notify the site's security force of a potential intruder.

Licensee detection capability addresses the following adversary intrusion tactics:

• stealth
• deceit
• force

Perimeter intrusion detection systems include:

• Volumetric systems, such as microwave and some electric field systems
  • Volumetric systems detect disturbances of a volume of space
  • For a microwave system with separate transmitters and receivers, this space is between the transmitter and the receiver.
  • For an electric field sensor, the space parallels the sensor and generator wires.
  • The effective detection volume must be sufficiently high and wide to prevent jumping across without detection and sufficiently low to detect someone attempting to crawl beneath it.
• Planar systems, such as fence disturbance and infrared systems, detect disturbances of the geometric plane containing the system elements.
• Security officers

Interior intrusion detection systems include:

• Door mounted balanced magnetic switches
• Interior volumetric systems
  • Ultrasound
  • Infrared
  • Motion detection closed circuit television
