Infrared Distance 120m, Wireless emitting distance 1km.How to choose active infrared beamsThere are different beams quantity such as 2 beams, 3 beams, 4 beams, 6 beams and 8 beams of photoelectric beam sensor. So, how many beams should I choose? The more beams means higher of protection height and longer of detection distance. For example, if the distance between two infrared holes is 35mm, then, for 3 beams sensor, the protection height is 70mm. For 4 beams sensor, any two neighbor beams are blocked, it will trigger alarm. Same for 6 beams or 8 beams sensor. So more beams will be with more security such as for bank. More beams means more power of infrared beam transmission and with stronger penetration to against interference of fog, sunshine etc. vedardalarm.com
