SPEED DETECTION SYSTEMS A speed detection device (often called a radar gun) sends out either a micro wave signal or beam of light. When this signal reaches its targ et, par t of the signal is reflected or bounced back tow ard the emitting gun. The time required for the signal to leav e the gun, bounce off an object, and return is used to determine ...

▼ L ASER The Laser Speed Detection System, also called LID AR (for Li ght D etection a nd R anging), uses a laser gun that emits infrared light pulses just outside the spectrum of visible light. Each reflected pulse measures the speed of the object coming to ward or going away fr om the laser gun. Unlik e radar , the laser gun emits a very narrow ...

INSTALLATION The LRD 767/LRD777 uses a highly sensitive horn-type antenna and IR laser sensor to receiv e laser/radar signals. Its sensitivity and range depend on the method of installation and the dir ection of the antenna/sensor in relation to the signal source. The inherent nature of radar w aves makes them r ef lect off metallic surfaces. This ...
