There are a few good reasons to install a driveway wireless alarm, but probably the best one is that no wires have to be buried and run into the alarm panel in the house. Although, many homeowners may not see an urgent need for a driveway alarm, there are those that live a long way from the street and would like to have a little notice when someone pulls into their driveway.
With some installations, the driveway wireless home alarm is not connected to main alarm and does not sound an alert or spur the automatic dialer into action. Those whose driveways are constantly used as turn around points for vehicle or who live in neighborhoods with a lot of stray animals may end up with a lot of false alarm calls if they were connected. They can be installed just to illuminate a small light or buzzer if someone or something cross the path of the alarm.
Used in private homes and businesses that can be effective in making people aware of any vehicles or people approaching the house or business. Some businesses, such as those that offer drive-through service can quickly install a driveway wireless alarm to notify the business operator of an approaching customer. In some instances, business install them on their entry doors to notify employees of a customer entering the business and that their presence in the front is needed.
There are many different types of driveway wireless alarm systems that can send a signal from 1,000 feet or more, depending on the system as well as offering different detection methods. The most common uses a light beam that sense when the beam is broken. As long as the light is making contact with the contact unit, the contacts remain open but if the beam is broken the contacts connect, completing the circuit and sending the signal to alarm unit in the house or business.
Those that remember the old gas station hoses that ran across the pavement in front of the pumps, they may see the rubber hoses at the end of a driveway as a type of driveway wireless alarm system. When a vehicle drives across the hose, it sends a signal to the transmitter, which in turn broadcasts a signal to the alarm receiver, activating the alarm. On the old gas stations, air in hose rang a bell inside the station to notify attendants that customer was outside waiting for assistance.
Another type of driveway wireless alarm system uses only one component and depends on the reflection of the transmitted signal to set off the alarm. These are better in areas with a lot of animals roaming around as it is the metal in the vehicles that sets of the alarm. Unfortunately, pedestrians are not always detected and could sneak up the driveway without being noticed. Depending on the broadcast strength of the driveway wireless alarm transmitter, they can be installed just about anywhere along the length of the driveway, eliminating the alarm from going off from people nosing their cars into the driveway just to turn around.
