Whether you have a long winding driveway or a short road leading to your garage, driveway sensors—like our top pick, HTZSAFE—are a smart way to monitor vehicles entering and exiting your property. These devices are easy to install and fit a range of budgets for long and short driveways.

Take a look through the different sensors and their effective ranges, and think about the geographic features around your home. Heavy foliage and hills may reduce those ranges, so figure out which sensor would work best for your home—and never be surprised by a visitor again.

What is a driveway alarm system?

Driveway alarm systems consist of two main parts: a sensor and a receiver. You can use driveway sensors as standalone units or as part of a larger security system. They can help people who live in homes with long driveways—you’ll know when someone is coming down your driveway before they're in your yard.

The downside to driveway sensors is that they're prone to false alarms. Possums and larger animals can trigger the sensors—a hassle you may not deem worth it.

Best wireless driveway alarm reviews

1. HTZSAFE: Best driveway alarm overall

Best budget

Price is accurate as of post date. Read full disclaimer.

The HTZSAFE wireless driveway alarm system starts at just under $70 for the receiver and one sensor. Additional sensors can be purchased for less than $40. You can pair up to 32 sensors with one receiver, which is very impressive.

Despite its low price, the HTZSAFE alarm has a great range for its receiver (457 metres) and sensors (15 metres), which is more than enough for a suburban home and may even suit larger rural properties.

pro Great range
pro Plug-and-play installation
pro 36 chime options
pro Cute design
con Low quality audio

Not only does it have a cute (yet surprisingly subtle) owl design, but installation is a cinch since the sensor is powered by AA batteries and the receiver simply plugs into the wall.

We also like the choice of 35 different chimes, all of which are nice and loud (though not the best quality sounding).

2. Guardline: Runner up

Price is accurate as of post date. Read full disclaimer.

The Guardline Wireless Driveway Alarm allows for over 150 metres between the sensor and the receiver, although heavy foliage and thick walls will reduce this distance. The sensors can withstand all types of weather and work without interference, and the receivers come with a battery backup as well as a 12-volt relay to link them to additional external alarms.

Guardline claims two years of testing went into each product, and the reviews seem to back that up. With just under 4,000 reviews on Amazon, the Guardline earns consistently high ratings—an impressive track record, no matter the product.

pro Weatherproof
pro Customisable tones for each sensor
pro Up to 16 sensors
pro Lifetime warranty
con Limited range
con Occasional false alarms

The Guardline driveway alarm comes with more than 30 customisable alert sounds and can be expanded to include multiple sensors—up to 16, or four zones with four sensors and one receiver per zone. You can pair specific sounds with specific sensors so you’ll always know where the motion is without looking. The only thing we're not fans of is the higher price.

3. eMacros: Best solar driveway alarm

Best solar
Price is accurate as of post date. Read full disclaimer.

The eMacros sensor can be as far as 457 metres from the receiver, and because it's solar-powered means you can set and forget it, never having to climb up and change the batteries.

On the downside, it has a maximum detection range of only 9 metres. It also offers fewer chime options than our top picks above (four vs over 30) and can only support an additional three sensors (which cost $69.99 each), so it's not quite as easy to build a larger system.

That said, we are fans of the receiver, which can either be plugged directly into the wall or powered entirely by AA batteries, meaning the whole system works off the grid (if that's your thing!)

pro Long receiver range
pro Easy to install
pro Solar-powered sensor
pro Versatile power options for the receiver
con Limited sensing range
con Up to 4 sensors only
con Only 4 chimes

Final word

Not only is the HTZSAFE one of the most affordable driveway alarm sensors, it also includes a lot of thoughtful features like unique alarm tones, a long wireless range, and support for up to 32 sensors.

When paired with other outdoor security equipment like motion detector lights, outdoor cameras, and other affordable motion sensors, driveway sensors can keep you aware of what's happening at your home whether you're there or not.

Driveway sensor FAQ

Driveway sensors use similar technology that of other motion sensors.

  • An infrared beam senses movement with heat and is more common in trail cams and outdoor sensors. Sometimes this is called a passive infrared or PIR sensor.
  • A magnetic probe only senses metal, making it less prone to false alarms triggered by pets or kids playing in the driveway. However, a magnetic probe motion detector is expensive.
  • A rubber hose sensor looks like those at a professional garage or drive-thru. When a car or heavy vehicle drives over the hose, the sensor triggers.
  • Photo beam sensors use light. When an object blocks the sensors, you’ll get an alert from the sensor.

Yes, it depends on the sensor type, but driveway sensors can pick up activities from people or animals. If you’re concerned about home invaders, package thieves, or other threats, installing a security camera in tandem with your driveway sensor.

It depends on your driveway. If your home borders a busy road, it’s best to move the sensor closer to your home to avoid false alarms from traffic. Sensors for longer driveways may be best halfway between your home and the beginning of your driveway.

Quick example

If you live in a rural area, you may have a driveway that looks more like a road than a private path. Putting a driveway sensor right at the front would result in too many alarms; after all, people often get lost and use driveways to turn around.

But if you put a driveway sensor about halfway down your drive, you’ll know when someone is coming to your home.

Driveway sensors do little more than let you know someone is approaching your home. However, this serves as the first line of defence in your home security system.
