Photoelectric Beam Sensor

The active photoelectric beam sensor consists of a Transmitter and a Receiver.  The infrared transmitter emits a beam of modulated infrared light that is directed at the infrared receiver. Active infrared sensor is a reliable method of intruder detection. Once set up they are extremely stable, with a high detection rate and low false alarm rate.

The mainly consideration of using single, double and quad photo beam sensors is the detection distance. Usually, for using indoor is no climatic factor so you can choose single beam infrared sensor. For outdoor beam sensor using, we will suggest you to choose double or quad beam sensors to fully ensure the highly reliabilities of detection distance.
