MLI (modulated light intensity) technology is based on the optical time-of-flight (TOF) principle. An active, non-scanning light source emits modulated near-infrared light. The phase difference between the light emitted by the source and the light reflected by the persons and objects in the field of view is measured to create a real-time topographic image of the monitored area. Our people and object sensing solutions Tailgate Detector, People Counter and Volumetric Object Classifier use this technology.
Key technology advantages:
High reliability in changing light conditions (sensor emits its own illumination)
Extreme accuracy due to specially programmed algorithms and extensive test matrices
Embedded software (all-in-one smart sensor)
Semi-automatic calibration and self-diagnosis
Easy installation due to small and low-weight sensor
Easy integration with existing access control or alarm systems
