Driveway alarms use motion sensors to detect someone’s (or something’s) presence, then send you an alert, so that you can check out what’s going on out there. A sensor is placed in your driveway to detect motion, and a receiver is placed in your home so you can hear the alert if it’s triggered. Both come in a variety of styles with various capabilities. Two of the most significant features to consider are the detection range (how much area a sensor covers) and the transmission range (how far about the sensor and receiver can be placed apart and still work).
The sensors use two primary kinds of detection technology for home driveway security:
Passive infrared (PIR): These sensors sense motion based on heat and movement. They detect most movement, including that of humans and animals. Most people tend to go with a PIR sensor alarm for their driveway since it provides greater protection.
Electromagnetic or probe: These sensors only detect metal, so while you’ll be notified of cars coming up your driveway, you won’t get notified every time a stray dog does.
Once in awhile unannounced visitors at your front door are welcome surprises, but more often than not, knowing when someone unexpected is coming up your driveway provides peace of mind. Driveway alarms are a simple and relatively low-cost way to get that peace of mind and help keep your family safe and sound. Luckily there are many different types available at different price points, so determine exactly what you need for your space and match it with your budget to find the ideal driveway alarm for your home.
