Strobe for license plate recognition: Near infrared illumination stroboscope

ESS-5315 Series

Allows video recording of vehicle numbers undetected by the human eye.

Main features

  • The ESS-5315 Series stroboscope incorporates a near infrared light source with a wavelength of 780 nm or longer.
  • It is capable of illumination and video recording undetected by the human eye.
  • ESS-5315-1 illuminates the area of 3.5 m×2.3 m at a distance of 6m, and ESS-5315-2 illuminates the same area at a distance of 20m.
  • The illumination wavelength can be modified by replacing the filter to suit the intended requirements.
  • It is capable of emitting 8 successive flashes at 0.5 s intervals, making it ideal for continuous recording of passing vehicles.
