Wireless Transmission Range

What does 'Line of Sight' mean ? - If there is an object between the two locations, does it mean they do not work ?

These are the other two main questions we get asked daily, you will notice that when the manufacturers of Wireless Driveway & Perimeter Alarm Systems discuss Transmission Range between the Detector & Receivers they always quote 'Line of Sight'.

Because of this you know the optimum range in good weather conditions, but what has to be taken into account is what type and how many obstacles are between the detectors and receivers, in most applications you will find a system that will work in your enviroment including the obstacles and weather conditions.

When you have an object in between the detector & receiver, it doesn't result in a total loss of signal, (it actually just reduces the signal) therefore reduces the working range of the system, the reduction is subject to what type of and how many obstacles you have.

Listed below is a guide showing the type of materials and reductions that may be seen.
