This system from Chamberlain costs significantly less than most other driveway monitors we reviewed, but it offers much of the same functionality. While its detection range is about 10 feet less than the Guardline system, its transmission range is significantly higher (up to 2,640 feet as opposed to 500 feet), so it may be good for those with large properties. Note, however, that range is under ideal circumstances, so if there are trees and other items in between, it likely won’t transmit that far.

Most customers give it high marks for dependability, effectiveness and range. However, some say it doesn’t hold up well in rain or snow.

Nerd Pros
  • Low cost make this an ideal choice for people on a budget.
  • High transmission range mean it may work well for those with larger properties.
Nerd Cons
  • No adjustable tones
  • May be sensitive to rain and snow
  • Some customers say installation is tricky.
  • Sensor batteries must be replaced regularly

  • Ideal for home and business

If you don’t want to be alerted every time a child chases a ball into your driveway or a dog wanders across it, then this system from Mighty Mule is a solid choice for detecting cars and cars only. You bury the sensor wand next to your driveway and it will detect moving metal within a 3-12 foot range.

Those in rural areas with long driveways and lots of deer and other animals may prefer this system to PIR driveway monitors. One note: If your driveway is very long, the transmission range on this alarm may not be long enough.

Nerd Pros
  • Few false alarms
  • Easy to install
  • Ability to connect additional sensors
  • Comes with a one-year warranty
Nerd Cons
  • Detection range is limited
  • Won’t detect intruders on foot

The sensors run on lithium batteries that are recharged by the sun, so there are no batteries to replace, and you can add more sensors as well. The receiver can be programmed to alert you with one of four tones, and the volume can be controlled.

Nerd Pros
  • Sensors run on solar-powered batteries making this the perfect choice if you don’t want to worry about remembering to change your batteries.

How a driveway alarm works

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.

Final thoughts

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.
