9 Best Window and Door Sensors - 2018

When an intruder attempts to pick one of your locks or climb through one of your windows, window and door sensors will sound an alarm, which will, in turn, set off a chain of events. Depending on your specific alarm system, a loud siren will blare, your monitoring company (if you choose to have one) will be alerted, your smartphone will chime. As with any technology, sensors vary greatly in price and functionality, but Security Seek has researched the best options for both DIY options and options that require a monitoring service.


If budget is a high priority, or you are not quite ready to commit to a full-fledged security system with all the bells and whistles, consider looking into the best door and window sensors for sale that do not require the additional expense of a 24/7 monitoring service.


SABRE Elite Door and Window Sensors

SABRE has a reputation for creating the best quality safety products, from wireless home security gadgets like door and window sensors to stun guns to the #1 trusted pepper spray used by police officers and consumers worldwide! SABRE Elite window and door sensors are affordable and easy for both renters and homeowners to install. Additionally, each Elite sensor requires its own unique 4-digit PIN so that potential intruders are unable to disable them. Most importantly, in our opinion, the SABRE Elite sensor is a standalone unit that does not require you to purchase additional products (such as a central hub, like the iSmartAlarm and Samsung SmartThings sensors discussed below).

When a door is opened, an intensely loud 120 dB alarm blares, which simultaneously alerts the renter or homeowner to potential trouble, helps to deter the intruder, and potentially informs neighbors. You can hear the alarm from up to 750 feet away. It’s important to note that these sensors do not have any adjustable volume settings; however, they do have three settings: alarm, chime, and silent mode. Both the alarm and chime are very loud, so if you frequently open doors, the loud alarm could potentially be a con (or you could opt to set the sensor to silent mode).

The SABRE door and window sensors look a lot like a garage door opener attached to your wall or door. If you’re using the sensor for your windows though, you can hide them easily enough behind a curtain. They are about double the size of a standard deadbolt and only come in white.


Samsung SmartThings Multipurpose Sensor

Samsung has its fingers in a lot of pies, as a prominent manufacturer of smartphones, appliances, televisions, home automation products, and security products, too! The SmartThings Multipurpose sensor is a tiny sensor, weighing in at about 1.5 ounces, but its size does not affect its functionality. The SmartThings sensor immediately alerts you to anything that opens and closes unexpectedly. It’s sensitive to the slightest change in temperature, so you can use it to control your thermostat, monitor your wine cellar, alert you to fires, remind you to close your garage door, or protect against intrusion.

The Samsung SmartThings communicates wirelessly with the hub (Samsung SmartThings hub and app required) to immediately inform you of any changes you have programmed it to monitor. In other words, it worries for you. The SmartThings hub and multipurpose sensor are super easy to set up; you simply need to download the SmartThings smartphone app. Adding additional devices and features to your system is voluntary and easy. Your system can be as simple or complex as you’d like it be.

In the modern world, battery life has become increasingly important and increasingly relevant. Many door and window sensors rely on 9-volts or AAA batteries, both of which require more frequent replacing. The SmartThings Multipurpose Sensor boasts an average battery life of two years!

While the SmartThings Multipurpose Sensor is super small, super functional, and super low-maintenance, it does have a relatively short range compared with other devices in its class. It must be within 50 feet of the SmartThings Hub in order to function properly, so it is important to plan the position of the hub to be closest to the most vulnerable entry points in your home. Additionally, as mentioned earlier, you must purchase the SmartThings hub in order to use the SmartThings Multipurpose sensors.


Elgato Eve Door/Window Sensor

Eve is a suite of products designed by Elgato to work specifically with your Apple devices to manage the interior and exterior of your home. Especially useful for people frequently on the go, the suite takes home management and home automation to the next level. It remembers what it calls “scenes,” such as a specific light dimness or temperature setting or series of settings or both, and brings back the specific setting with just one movement.

The Elgato Eve door and window sensor, like all the Eve products, is designed to work in conjunction with Apple HomeKit, and it is one of the few products on the market designed to do so. Compatibility with Apple HomeKit enables the Eve products to become part of and work to enhance a greater ecosystem of variously branded devices to create the ultimate automated home, all of which can be controlled, tweaked, and orchestrated through Siri.

Eve by Elgato remembers “scenes” from your home, which you can “play back” at command. The Eve Door & Window sensors are contact sensors that work wirelessly through Bluetooth, so you’ll need a 4th generation Apple TV or higher, a HomePod, or some Apple device capable of functioning as a hub for HomeKit. The sensors are powered by long-lasting 3.6V lithium batteries.

Conveniently consult with Siri to see if you left a door, window, safety gate, or cabinet open. Open your door to perfectly optimized lighting and soft music (or whatever) playing. Have your heater or air conditioning pause when you open a window, but only if it’s too cold or too hot outside. Like the Apple products it is meant to enhance, Eve has an ultramodern design that is discrete, so it won’t attract the unwanted attention of burglars or visitors.

Note: Android users need not apply. The biggest con here is that Eve only works with Apple devices, and not only that, Apple devices with iOS 11.3 or later.


iSmartAlarm Contact Sensors

iSmartAlarm offers an extensive array of security and home automation products designed to enhance your security and home automation, without any contracts or monthly fees, and easy to install. In particular, iSmartAlarm technology uses magnetic bonds that alert your device and sound the alarm when broken. Standard security technology monitors vibrations, which are more prone to more false alarms.

The iSmartAlarm contact sensors are extremely easy to install, deinstall, and move. They attach to any surface using a double-sided adhesive, and they come in packs of two. Additionally, the iSmartAlarm contact sensors can easily expand to include other features, including motion sensors, Smart Switch, which allows you to control any appliance from anywhere, sirens, and a suite of smart cameras with an array of stunning features. Or, you can simply order the 2-pack of contact sensors. Totally up to you! And never any monthly monitoring fees or contracts. iSmartAlarm contact sensors are wireless; however, they do require you to use the iSmartAlarm CubeOne central hub in order to communicate wirelessly. This is where the plot thickens. In order to get the CubeOne hub (not sold separately), you must order one (any) of the iSmartAlarm security packages, the most basic of which is the Plus Package. The Plus Package includes three of the contact sensors, a motion sensor, a remote tag, and an iSmartAlarm window decal and will run you about $200. The good news is that there are no additional costs beyond the cost of the package you choose (unless you simply want more stuff).

Another thing to consider is that the iSmartAlarm sensors are not as secure as the SABRE Elite sensors because they do not each have their own PIN. The sensors, which adhere to doors and windows, can be easily removed (a pro and a con). If you want them to be more secure, you’ll have to add stronger glue or mounting brackets at your own expense.


Panasonic Wireless Door/Window Sensor

Panasonic is a technology company that engineers an array of electronics from televisions to cameras to appliances. Not often the first company that comes to mind when thinking about security, Panasonic’s wireless door and window sensors make our Top 5 here. In particular, the Panasonic wireless door and window sensors offer one-touch, real-time syncing with the Panasonic hub, which allows you to arm and disarm the door and window sensors from your smartphone with one touch.

The Panasonic wireless door and window sensors are long and narrow, which allow you to place them in window sills and door jambs so that you don’t even notice they are there. Because Panasonic offers such an extensive array of products, it allows you to build an extensive home automation network where you can connect your television, camera, smart outlets, and any other Panasonic device you own or you can think of to your Panasonic hub (sold separately).

The Panasonic wireless sensors to require you to purchase the KX-HNB600W Panasonic Hub to use them. This requirement, however, is common among sensors. The only sensor on this list that doesn’t require the purchase of a hub in order to operate is the first on this list: the SABRE Elite.


If you want to take your security system to the next level by adding a monitoring system to do the work of watching for you, you will pay a little more, but your home will be more secure. Below we’ve compiled a list of the best door and window sensors that do require a monthly monitoring system. Not coincidentally, they also happen to be some of our favorite monitoring systems.


Vivint Door/Window Sensor

Vivint is a technology company that specializes in creating simple, intelligent, and affordable home solutions, including home security and automation, energy management, high-speed internet, and local cloud storage to over one million customers in the United States and Canada. Founded in 1999, Vivint’s roots are in selling and installing security systems. In 2006, it expanded into a security monitoring provider, and in 2012, was rebranded as Vivint. In 2013, Vivint was ranked by Forbes as one of “America’s Most Promising Companies,” and in 2017, it was named in Fast Company’s “World’s 50 Most Innovative Companies.”

Vivint features a top-rated app, customizable alerts and notifications, intelligent home automation, mobile climate controls, live video feed, an array of smart cameras, and 24/7 monitoring. Vivint offers two kinds of door and window sensors. For added security, Vivint’s sensors use magnetic locks as opposed to vibration to detect when someone is attempting to enter your home. Vivint additionally offers the more traditional sensors that will fit into the recesses of your window and/or door frames.

The design of Vivint’s sensors, including anchor screws and a cover, prevents tampering and unauthorized disarming. If someone is attempting to tamper with the device, the security panel is alerted, which, in turn, alerts the Vivint monitoring agency. The sensors also have a good range, working within 350 unit of the panel.

Note: Vivint’s door and window sensors will not work if the temperature is below 32 degrees Fahrenheit, so they will need to be placed in a temperature-controlled environment.


Link Interactive Door/Window Sensor

Link Interactive is an affordable, fully customizable, DIY (do-it-yourself) security system that is highly recommended by customers on Yelp, Amazon, BBB, and Angie’s List. Like the other security systems on this list, it offers/requires 24/7 monitoring; however, the pricing is simple. Your monthly monitoring will run you $35.99/month. If you want Link Interactive to do video monitoring as well, it is an additional $5.

Link Interactive offers three different types of sensors, as different environments call for different things. Link offers standard window and door sensors, recessed sensors that can be hidden in door and window frames, or sensors that are sensitive to tilting motion, which are perfect for garage doors. All equipment and monitoring comes with a 30-day money back guarantee and a 3-year warranty on all equipment. It’s worth noting that, unlike many other sensors on this list, these sensors do come with screws and are thus much more difficult to tamper with. These sensors are also alerted by broken magnetic bonds as opposed to vibrations.


Frontpoint Door/Window Sensor

Frontpoint is relatively new to the scene, but it has quickly made a name for itself among the most innovative security companies, with over a 4.5 star rating on Consumer Affairs. Frontpoint serves homeowners and renters alike. Frontpoint believes that securing your home should be both easy and safe, and it is committed to being both. In fact, Frontpoint offers a 30 day, no-risk, money-back guarantee that you will be happy with the Frontpoint service.

The wireless door and window sensors are shipped to you pre-configured and ready to install. You can find step-by-step instructions on how to install them online. The process doesn’t require any special skills or training and can be completed in under 30 minutes. Since the sensors are peel-and-stick and completely wireless, they are extremely easy to pack up and move, if needed. Because they are easy to remove, you may want to reinforce with anchor screws (sold separately) in easy-to-access areas.

The Frontpoint security system is 100% wireless/cellular, which, along with advanced technology, makes it virtually impossible for any random intruder to overcome. The system is monitored 24/7, and the system is checked each and every hour to ensure every piece is active and functioning properly.

The Frontpoint app can support up to 39 sensors, which means that your home is monitored with precision. Cool gadgets like doorbell cameras and wireless indoor cameras increase this awareness, allowing you to be aware of your home (even when you’re not there) like you never have been before, all through the seamless app on your phone.

The sensors can monitor more than just windows and doors. You can attach them to your medicine, liquor, or kitchen cabinets, your desk drawer, or even the cookie jar!


Protect America Door/Window Sensor

Established in 1992, Protect America is known for its affordability. There are two outstanding features that set Protect America’s door and window sensors apart. The first feature is that each sensor comes with a lifetime warranty. In a plastic world of replaceable things, a lifetime warranty is almost like a unicorn. Most security systems offer anywhere from one to three year warranties on their equipment.

Protect America is not the only security system that identifies potential security threats when a magnet is broken, as opposed to detecting vibrations, but it is still not a common practice in the security industry, so it is worth noting. Monitoring for broken magnets instead of vibrations cuts false threats down to almost zero percent.

Like other security providers, Protect America offers wireless sensors that communicate in real time with you via an app. And like other security providers, Protect America’s sensors are not super resistant to tampering. They do not come with anchors, so, like Frontpoint, you will need to reinforce at your own expense if you deem it necessary.


Security protects us from others and from ourselves. A child gaining access to dangerous pills inside a medicine cabinet is potentially much more devastating than an intruder breaking into your home. It’s also more likely to happen. The range of choice and cost offered by the companies discussed above makes securing the people and the things that you love more accessible, easier, and more customizable than it has ever been. You can start small, as small as one single, standalone SABRE Elite door sensor and build over time to accommodate life changes. Or you can have a company like Vivint or Protect America do the work for you. Whatever you decide to do, be safe!
