Early warning and tracking of potential threats is increasingly necessary to electrical substations, oil refineries, and petrochemical plants. These are just a few of the applications benefiting from compact surveillance and intrusion detection with Reveal radar sensors.A complete Reveal system includes one or more of the Reveal sensor heads. These radar units are field-deployed on a variety of structures. Each unit “sees” what is going on in their field of view, transferring the data from the unit into the Reveal Processing Unit (RPU). The RPU provides the graphical visual indication, user interface, and a high-level computer integration for video, access control, and security management systems.
