Over-Height Detection

Intelligent Warning Systems

Alerting over-height vehicles in advance of potential collision ahead. 

Over-Height Detection: Infrared transmitter and receiver sensors are mounted on either side of the road in advance of the low structure, creating an infrared beam over the road. When an over-height vehicle breaks the infrared beam, the receiver sends a wireless signal to activate the warning alert, notifying the driver that their vehicle won’t clear the structure ahead.

  • Sensor height tailored to each system
  • Sensor lights confirm operation
  • Solar or AC power
  • Variety of warning alerts
