Introduction

Infrared Speed Cameras have become a pivotal tool in traffic management, offering a reliable method to detect speeding vehicles. By employing advanced sensors and technology, these cameras can accurately measure vehicle speed, ensuring road safety and regulation compliance.

Infrared Speed Camera Technology

Infrared speed cameras are equipped with sensors that operate within the infrared spectrum. These sensors work by emitting infrared light and detecting its reflection from moving objects. Below are some specific technical parameters involved in their operation:

  • Wavelength: Typically, these systems use wavelengths between 850 nm to 950 nm for optimal reflection and reduced interference.
  • Detection Range: Modern infrared cameras can accurately detect vehicles within a range of up to 200 meters.
  • Measurement Accuracy: The speed measurement error margin is usually less than 1 km/h.

Detection Methodology

The primary method for detecting vehicle speed relies on the Doppler effect, where the frequency of the reflected infrared signal changes relative to the speed of the vehicle. Here's how the process works:

  • An infrared signal is emitted towards the road.
  • As a vehicle moves through the beam, the signal is reflected back to the camera sensor.
  • The camera calculates the speed based on the frequency shift of the returning signal using the formula:
  • Speed = (C * Δf) / (2f0), where C is the speed of light, Δf is the frequency shift, and f0 is the original frequency.
