The security of your home is not something to take for granted. You never know when a thug might break through your window. And since you can’t possibly wait and keep an eye on your property all the time, equipping your home with the proper sensors goes a long way to constantly keep tabs on your property.

Of all home security systems, door and window sensors are the most popular, owing to their simple design, affordability, reliability, and affordability. Today, there are plenty of fantastic options when it comes to such devices, and it’s never been a better time to go shopping for a quality set of door and window sensors. 

What to Know About Door and Window Sensors

Knowing how your door or window sensor works goes a long way to achieve maximum system reliability. It also helps in adjustments, just in case you need to change a few things or add more sensors. In addition, door and window sensors are the backbones of other home security systems, and, therefore, you’ll need to have all the relevant information right.

So, most door and window security systems come as a package of several sensors, with the provision of adding more, obviously at an additional fee. Ideally, these sensors should be placed at every door and window. Then, if an intruder opens the door or window where the sensor is located, it automatically notifies you by triggering an alarm.

How Do Door and Window Sensors Work?

Door and window sensors come in two parts. One part attaches to your door or window while the other fits the frame. They are usually held in place by an adhesive, even though some can be screwed into position. When in position, these two parts are generally next to one another. The moment an intruder opens the door or window, and the sensors move apart. They send signals to a centralized alarm system that will sound the alarm.

You might have probably asked yourself how these sensors notice that someone has trespassed your door.

These sensors rely on either a magnetic property or light beam to determine whether your door or window is open or not. In the first scenario, two sensors are placed in contact by magnetism. When the door is opened, and the sensors lose connection, they trigger an alarm.

The same happens to the sensors that rely on light. One sensor produces a light beam while the other acts as the receiver. Once the light travel path is interfered with while the system is on, your alarm activates.

Types of Door and Window Sensors

There are two main door and window sensors; wired and wireless sensors. They perform the same functions but use different approaches.

As their name suggests, wired sensors are wired into a power source, while wireless sensors only require batteries to function. As a result, wired sensors will take you more time and effort to install than their wireless counterparts. Wireless sensors work with batteries that lose their power with time and need to be checked regularly.

We also have shatter sensors that detect the sound when your window is broken. These don’t have to be connected to your window to work, and, for that reason, some people find them more convenient.

Simplisafe Entry Sensor

Simplisafe Entry Sensor

The Simplisafe Door and Window sensor is one of the smallest but smartest door and window sensors out there. It comes in either a pack of 1 or 4 but is well known for its small size.

Simplisafe puts the best foot forward when it comes to installing its devices. Almost anyone can do it because it involves only sticking the device’s sticky end to a flat surface. The same applies to the Simplisafe Door and Window Sensor.

The entry sensor comes with an adhesive surface that can be easily attached to any flat surface, most probably your door and window and their frames. In addition, its magnetic property is reliable enough to offer a 2″ allowance between the hub and sensor. That makes it more reliable for thicker doors or tight spaces. Moreover, you get optional installation materials like screws for convenience.

After installing, you now need to connect the Simplisafe sensor to the Simplisafe Home Security app and link it to a central hub/system that comes with a speaker for timely notifications and status checks. 

For example, the sensors chime when they notice a door or window opening activity.

Ring Alarm Contact Sensor

Ring Alarm Contact Sensor

Ring has had a good history with manufacturing home security systems. Among its broad portfolio of items, the Ring Alarm Contact Sensor happens to make it to our top picks for the best door and window sensors.

What’s peculiar about the sensor is how easily it interacts with other Ring Smart devices and professional monitoring. So what else does it have to offer?

One of the features that will impress you is how easy it is to install the Ring Alarm Contact Sensor. It comes with a magnetic property and adhesive strip for attaching against the wall. If the distance between the magnetic and non-magnetic sides surpasses one inch, then the alarm goes off, and it’s a sign that someone has accessed your house either via the door or window. 

After installing, you’ll need to connect the sensor to a base station (Or Ring App) for notifications whenever movement is detected. For example, when you connect the sensor to your app, it automatically starts sending notifications when your door is opened. You can’t possibly underestimate the convenience of a timely warning.

The Ring Alarm sensor is compatible with Alexa, Google Assistant, Siri, Android, and iOS. That means you can make voice commands while trying to check the status of your doors. It operates on a battery since it’s wireless, and the battery lasts around three years before you can find a replacement.

The Ring Alarm Sensor’s system connects to a Z-wave connection portal that keeps it active all day long. So you won’t miss any notifications because the system was sleeping. That’s a great plus for the reliability of any smart home security system.

However, there’s a limitation to the performance of the Ring Alarm Sensor as you’ll be required to constantly update the system software for the app to perform optimally.

Pros and Cons of the Ring Alarm Sensor


  • Offers timely mobile notifications
  • Systems remain active all through
  • The sensors are reliably sensitive and error-free
  • Easy to install

GE Personal Security

GE Personal Security

The GE Personal Security is an absolute bang for the buck! It is an absolute bargain, considering the features and price tag. However, you don’t get app integration or other wireless capabilities for a reduced price. Nonetheless, it would make an excellent choice for those who need a simple door and window sensor.

The GE Personal Security door and window sensor is one of the loudest sensors. Nevertheless, it is safe for you to install it in places considerably far from your home. However, if the sound becomes irritating, the sensor comes with a chime profile that is a little more silent. Again, we have a silent mode, but you shouldn’t put that on unless you’re so sure you’re safe.

GE Personal Security released an upgraded version that comes with a 4-digit code to prevent any intruder from turning off the alarm. However, it is more expensive than the base version.

As said earlier, the sensor doesn’t support a mobile app or web compatibility. Moreover, there are no intelligent controls. Again we don’t have Alexa or Google Assistant support. Therefore, you might need to consider buying it before making your final decision. However, if you have the financial capability, you can use the GE Personal Security door sensor to complement other more intelligent sensors or in less-sensitive places.

Pros and Cons of the GE Personal Security Door and Window Sensor


  • Loud 120 dB siren
  • Affordable on a multi-pack basis
  • Offers silent and chime modes


  • It doesn’t support a mobile app
  • Not compatible with smart home service

Honorable Mentions

Other hubs have a decent array of features to portray, but in one way or the other, they don’t make it into the best five. These are;

  • Wyze – Wyze is a reliable company when it comes to security systems. They ranked among the best in Door and Window Sensors, but their latest version wasn’t welcomed by users all over. It warrants that you pay for monitoring, even when you’re purchasing and using the starter kit. Wyze’s add-on sensors boast the lowest prices in the market but aren’t the best for people looking forward to low starting costs.
  • Geeni – Geeni is an intelligent door sensor compatible with Amazon Alexa and Google Assistant. However, it can’t connect with IFTTT and Apple HomeKit. It comes with inbuilt Wi-Fi so that you won’t need a hub. The Geeni door sensor is an excellent choice if you need a standalone security system. It comes in a pack of two and is affordable.
  • Kangaroo – Just like the Geeni smart door sensor, the Kangaroo doesn’t require a hub; it comes with inbuilt Wi-Fi. It is pretty small and perfect for tight spaces. It is compatible with Google Assistant and Amazon Alexa. However, you need to subscribe to access smart home services and unlock phone and text messaging notifications.


That is a roundup of the best Door and Window Sensors. Link is the best option overall. The starter kit comes in a set of four, but you can add other sensors if you have large premises to monitor. The sensor is compatible with Amazon Alexa and other smart services. Again, you get to enjoy the reliability of a mobile application that is intuitive and easy to use.

All other sensors in the list are of good quality. However, it would be best to remember that sensors are not locks. If you need to install it on your door, you might want to consider pairing it with a smart lock for enhanced security.
