Lesson 4_Why Quad Beams Sensor Can Be Used Farther and More Stable

Quad beam has 4 parallel beams that mean multiply by 4 times of the infrared. The farther infrared emits distance is, the larger beam receive area is. Therefore, if the detection distance is 100 meters and the beam diameter is about 3 meters, which covers the entire receiver.
Synchronized quad beams reduce false alarms caused by wild animals, flying birds, falling leaves or litter, plastic bags, etc. blowing through the beams.

#Quad infrared stability is the best for the longest detection distance
#Large detection area
