A driveway security alarm is different from a home security alarm in which it monitors any activities around your driveway. It can help prevent accidents from occurring and thieves from breaking into your car or house.
Driveway alarms are for people or businesses with long driveways or driveways that can't be seen from the house so that they know when company / customers arrive. They are also useful for swimming pools and ponds as a safety device.
The purpose of a driveway alarm is to notify the homeowner if there is an intruder lurking around their house, however sometimes they do go off from animals and wind.
For anyone with a long driveway or someone who simply wants to know in advance when someone pulls into the driveway, a driveway alert alarm is ideal These alarms are simple to install. The sensor will generally come with a stake that is drive into the ground. This transmits to the receiver in the house that will emit a beep or alarm sound when a vehicle enters the driveway. The placement of the transmitter is important. It should be at the end of the driveway, but not in a location that will be tripped by passing cars.

A driveway alarm can be used as an extra form of security for your residence. For example, if you have a long driveway because you live far off of a road, the alarm will trigger when a vehicle passes the sensors and will relay a sound of your choosing in your home to alert you of a coming vehicle. It could also be used at a business to alert the owner that a package is about to be delivered or a new customer is coming. http://www.absoluteautomation.com/driveway-alarm.html
It may not prevent this from happening if the tresspassers don't know that you have a security system. If your driveway security alarm makes a loud noise when people tresspass, then it will be very effective.
