Best Driveway Alarms & Sensors of 2019 [Guide]

13 May 2019

An important part of your security plan is keeping tabs on what's happening around your home.

Whether it’s monitoring your home for uninvited visitors or keeping tabs on stray pets crossing your property, a driveway alarm can be a useful tool for any homeowner.

What are driveway alarms?

Driveway alarms are essentially sensitive motion sensors and receivers. When something moves into the path of its infrared beams, you are immediately notified.

Many driveway alarms can also detect outgoing movements, so you can tell which way your pet went or if a family member is entering or leaving the premises.

There are many benefits to installing a driveway alarm, however, with so many on the market, it’s helpful to know how to differentiate between them to find the one that best meets your security needs.

What to look for in a driveway alarm

  • Clear upgrade paths: Can the driveway alarm systems be expanded to include a number of receivers and sensors?
  • Weather-resistance: Is the alarm designed with weatherproof features?
  • Status check: Is the user alerted if the driveway alarm connection is still working or if the signal is lost?
  • Ease of installation: Is the alarm system wireless or wired?
  • Alternative power options: Does the product use rechargeable batteries or single-use battery, or has an alternative power source
  • Sensor effective range: What is the range of the sensor to detect motion?
