A sophisticated dual-beam set comprising an emitter and a receiver. The little solar panel on top of each unit keeps the internal battery continually topped up, and the system will happily work with no external power source, even in our unreliable climate.
A variety of beam-lengths is available, from 40m to a whopping 200m, allowing you to protect very long stretches of perimeter incredibly economically. Up to eight beam sets can be used on a system, depending on the receiver selected.

40m - £169

100m - £219
