Wireless Intercom & Bell Systems Transmission Range Information

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.

Materials: Degree of Reduction (Example Applications)
Air: None: (Open space, inner courtyard).
Wood: Low: (Door, floor, partition).
Plastic: Low (Partition).
Glass: Low (Untinted windows).
Tinted Glass: Medium (Tinted windows).
Water: Medium (Aquarium, fountains).
Living Creatures: Medium (Crowds, animals, people, plants).
Bricks: Medium (Walls).
Plaster: Medium (Partitions).
Ceramic: High (Tiles).
Paper: High (Rolls of paper).
Concrete: High (Load-bearing walls, floors, pillars).
Bulletproof Glass: High (Bulletproof windows).
Metal: Very high (Reinforced concrete, mirrors, metal cabinet, elevator cage).

Long Range Wireless Door Bell System.

Using components from our long range wireless driveway alarm systems, we have been able to design an entrance or gate door bell system with a very impressive working range of 900 metres (line of sight) that actually works.

This 'Long Range Wireless Door Bell System' was designed, due to the fact that were constantly being asked by customers who had tried all the systems being sold in the large high street home improvement stores with no success. This is a true wireless long-range door bell button system, with the ability to use up to four caller units going back to one receiver.

The outdoor weatherproof bell push button can be mounted inside or outside at the exact location that is required, without having to worry about the best position for transmitting radio signals. This bell button is connected to our universal wireless long-range transmitter by simple two-core bell cable, the length of the cable we supply as standard is three metres, but it can be extended upon request. The universal transmitter is then positioned in the most suitable location to suit sending a radio signal, it can be inside or mounted outside inside a weatherproof
plastic box. The universal transmitter is powered by a 9v PP3 battery.

The receiver is simply plugged into a 13-amp wall socket, and gives one of four chimes when the wireless signal is received. The receiver also has the ability to trigger an external siren or flashing stobe light, for customers who may be working away from the receiver or in a noisey enviroment. The receiver also has four dry relays that can be used to trigger all types of gadgets.

We also off a portable pager, that has an impressive working range of 600 metres (line of sight)
for customers who are on the move.

Please read the following advice, which we hope may help you in deciding which is the best wireless intercom or bell system to suit your application & budget.

Please take note of the distance and terrain between the position you would like to fit a push button or caller station to the location of the receiver (the distances quoted by the manufacturers are always line of sight, which results in a lower working range in most cases).
Each wall, building or tree between the two locations will reduce the signal by various degrees, as a general rule, windows will reduce the signal only very slightly, modern buildings may reduce signals by 10 - 20 percent and thick stone built walls & buildings can reduce the distances up to 50% or more, if you are not sure please ask us.
After you have decided upon the distance, you can start to narrow down your options in choosing a system for your application.

If you are not sure that the system you have decided upon, will work when you try it, don't worry, simply send it back to us by return for a full refund (see terms and conditions)
Due to the nature of wireless equipment, no company can guarantee with complete
assurance that a system will work in any given application.
