SoundVue, from Intelligent Instruments, uses innovative environmental protection technology to reduce the impact of excess vehicle noise and allow enforcement authorities to take appropriate action.

The “Hydra” sound radar detects the sound emissions of the loudest vehicle, even on a busy road with multiple loud vehicles. It draws a rectangle around the loudest vehicle, and pinpoints the precise location of the sound emission. If the sound emission exceeds the legal threshold, and if the sound emission can clearly be identified to a precise vehicle, then the ANPR cameras retrieve the vehicle’s license plate. An encrypted file is then sent to the relevant authorities, with the time and location of the infraction, the license plate, the video recording as well as the audio sequence of the scene.

Not-A-Loud's patented noise camera system NoiseTrackerTM uses a sound level meter to trigger a license plate camera, a wide-angle camera, and a microphone array that localizes the noise source for indisputable identification of the offending vehicle on single-lane or multi-lane roads.​
