Even the most average of homes has a long driveway, which means it is impossible or at least very difficult to see accurately who arrives at your home. Being able to see who drives up to your home can greatly improve the layer of protection for your home. That is the rationale behind so called driveway alarm systems.

The majority of driveway alarm systems operate by placing infra red sensors at certain primary parts of your home such as in the yard or in the driveway itself. The sensors are then connected to a transmitter that will send a signal to the receiver in your home. When a vehicle or a person steps through and thus breaks the beam, this will then send a signal to the transmitter. This in turn notifies the owner that someone is in the perimeter of the house. A magnetic sensor can be used to detect the presence of vehicles with a greater degree of precision.
