Whether you want to protect your home from a possible intrusion, don’t want to miss a home delivery or like to know who’s approaching before he rings the doorbell, a driveway alarm is a useful addition to any home security system.

The driveway alarm comes in a variety of styles; each of them has its unique way of protecting your property and alerting you to a presence there. Both wireless and handheld models of the driveway alarm are available in different detection ranges from 1,000 feet to 2 miles. Some use tones to alert you, whereas others use recorded messages.
