Abstract
The invention relates to a motion detector system (2), a lighting system (14) with such detector system and a method for detecting moving vehicles and/or pedestrians. The motion detector system comprises: —a first motion detector (6a, 6b) for detecting vehicles and/or pedestrians having a speed in a first speed range, the first detector being arranged to detect moving objects in a first detection zone (d1, d2) having a first size, the first size determining the first speed range; and —a second motion detector (8a, 8b) for detecting vehicles and/or pedestrians having a speed in a second speed range, the second detector being arranged to detect moving objects in a second detection zone (d3, d4) having a second size, the second size determining the second speed range.
