Q:
How is a dual-beam or tripple-beam better than a single beam when the beams are so close together? i.e. if I mount the sesnors at a height of 1.2m, how is is more difficult to get under or over a tripple beam? - Asked by

A:
Hi there the only difference between the double and tripple beams are that there is a extra beam to make sort of a wider barrier line. These are visible, and if mounted 1.2m high, and a perpetrator can see them, he can still move under the beam undetected.
Please have a look at the following links, these are for our strip beams. These come in various lengths 70cm, 115, 140 and 200cm these are much harder to go under or over due to the physical length of the beams.
