Scan-Beam uses a very narrow "beam break" detection system suitable for mounting along a perimeter fence line. The detection area is defined between the transmitter and receiver units with a simple threshold control to set the width of the detection area. Installation and set up is straight forward using the web browser based menus.
Scan-Beam is ideal for mounting close to ground level, next to a physical fence in high security environments to detect walking, running or crawling intruders. The system forms a 3D volumetric detection area between the transmitter and receiver units. Movement of intruders through this sensitive area causes an alarm to be raised. The 24GHz operating frequency has improved detection performance compared to older 10GHz (X band) equipments as well as increased immunity to interference from air traffic control, military and marine radar systems.
