The Best Window and Door Sensors in 2019

Doors and windows are the most obvious entry points for potential burglars, so securing them is crucial to making your home safer. When your doors are already deadbolted and your windows are fitted with locks, there’s no better way to make these entry points more secure than with window and door sensors, which alert you to any unwanted entries into your home.

Below we’ve hand-picked some of our favorite door and window sensors so you can better protect your home from the threat of break-ins.

Consider a home security system

For a more comprehensive home security solution, consider installing a home security system. In addition to window and door sensors, home security companies offer additional features like security cameras, professional monitoring, and more. We recommend Frontpoint for its stellar customer service and wide range of home automation.

Overall rating

4/ 5

As the first line of defense against break-ins, Frontpoint puts window and door sensors at the forefront of its home security plans. The sensors are portable and easy to install, so you can move them around easily when needed. Frontpoint sensors also integrate wirelessly to your home security control panel.

The moment one of your door or window sensors is triggered, an alert is sent to both your control panel and the Frontpoint monitoring center. But they’re not useful just to monitor for break-ins. You can also place them on cabinets and in drawers to keep the kids out of trouble in the house.

Best DIY window and door sensors

You can still upgrade your home’s security with self-install door and window sensors without investing in a home security system. In most cases, these devices are interchangeable, meaning one type of sensor should work for the all the doors and windows in your home.

Below we offer our top picks for door and window alarms so you can find the right solution for your home. While all the products below are pretty affordable, we focused more on the size, reliability, and available features of the sensors.
