Gardasoft VTR4 - Traffic Monitoring LED Strobe Light

  • Lighting units, specifically designed for traffic technology applications (ITS)
  • Provides a very powerful, high intensity LED strobe IR and white light
  • Allows capturing vehicles under different weather conditions throughout the year and 24 hours per day
  • No need to restrict the flow of traffic due to its large area of illumination
  • Compact IP66 enclosure and robust cabling designed for outdoor use or very harsh environments
  • Captures entire vehicles, even unter difficult conditions
  • Fully integrated with internal timing, intensity control, trigger input and long distance communications
  • Available with Ethernet or RS232 interface
  • Allows for setting parameters over longer distances
  • Free-running mode operation from a programmable internal timer possible
  • Features synchronized camera recordings thanks to trigger input
  • Pulse Drive Power up to 3.3 kW
  • Very low maintenance
  • Accessories such as sun protectors or tilt-mountings available


  • Available with different LED colors and IR wavelengths (standard colours: white and IR 850 nm, further colours upon request)
  • Available with two reflection angles (12° and 30°; 50° optional)
  • Power supply 24V DC, optionally 12V DC
