The 7 Best Door & Window Alarms To Secure Your Home (2017)

How Door & Window Sensors Can Help Secure Your Home

Door and window sensors are a common piece of home security equipment. They’re compact, easy to operate and install, and loud enough to rouse the deepest of sleepers and scare off thieves.

Roughly 4,800 burglaries occur in the United States every single day, or one every 18 seconds. Chances are you know someone that’s been the victim of a burglary attempt. But even if you don’t, a good door or window alarm is an essential home security device that protects you and your family while deterring potential break-ins.

There are a variety of door and window sensors, with the majority being wireless and magnetically triggered. Essentially, each alarm is comprised of two separate pieces: a control box (the alarm) and a sensor (the trigger). These are aligned along the side of a door or window, with the sensor attached to the door itself. The magnets create a field that, when broken, triggers an alarm in the control box.

What should you look for in a decent door alarm system?

First, consider what you’re trying to secure. Door alarms can be used to keep small children from wandering outside or track their whereabouts. Alarms can secure liquor cabinets, office drawers and ground floor windows.

Then consider what features you’d like: a simple alarm that triggers as soon as someone opens a door, a gentle chime that notifies you if a window is cracked open, or a delayed alarm system so you can come and go frequently without constantly tripping your security network.

Whatever your home security needs may be, here are our top picks for the best door alarms you can buy to quickly and efficiently secure your home.

Wsdcam Wireless Anti-Theft Remote Control Door Alarm

Ever wish you could control your house alarm like your car? With Wsdcam’s wireless remote control alarm, you can arm and disarm your home security with a small remote (which looks strikingly similar to an electronic car key).

You can also pair multiple alarm units to the same remote, or multiple remotes to the same alarm, so you and your family can come and go with the push of a button.

Standout Feature

The remote control access really shines on Wsdcam’s alarm. Each remote lets you interact with the following features.

  • Arm/disarm: Sets the alarm to sound when a door or window is opened.
  • Panic: Instantly activates every alarm connected to the remote, in case there is an emergency or an intruder.
  • Doorbell: A simple ding-dong chime that alerts you when a door is opened or closed.

Additional Features

  • The “Arm” button is larger than the other buttons on the remote, making it easier to access when leaving the house or office.
  • Low battery indicator lets you know when it’s time for a fresh pair of batteries.
  • Alarm uses 2 AAA batteries (not included)
  • Remote control uses 1 12v/27a alkaline battery (included)

Pros

Simple instructions and adhesive backing make installation an easy process. “Panic” mode is a potentially life-saving feature that not only sets off every alarm controlled by the remote but will likely alert your whole neighborhood given how loud the actual alarm is.

Drawbacks

Of course, the convenience of a remote control comes with its own headache. The Wsdcam alarm can only be controlled by the remote—there are no physical switches on the alarm itself. This means you’ll need additional remotes (sold separately) for everyone in your home.

Even more concerning, if you lose your remote, then you not only lose control of the alarm but you’ll have to remove the batteries on the alarm in order to make it stop ringing.

Summary

The Wsdcam Wireless Anti-Theft Remote Control Door Alarm is for anyone seeking convenience as well as security.

However, not being able to control the alarm without a remote could lead to unexpected dilemmas. If you don’t mind purchasing multiple remotes for friends and family (and keeping a few spare remotes handy to replace lost ones), then this is a great alarm with a variety of features.

Why It’s Our #1 Choice

Despite the mandatory remote control requirement, the Wsdcam is an exceptional and affordable alarm that provides a wealth of convenience with the touch of a finger. You can easily arm or disarm your home security network from your car or tucked away in bed. We love the fact that there’s no need to dial in a passcode each time we want to leave the house, or race to turn the alarm off when we get home.

SABRE Wireless Home Security Door Window Burglar Alarm

SABRE, producer of the world’s best selling pepper sprays, is now applying its safety experience to home security. The result is SABRE’s affordable wireless door alarm, an easy, practical way for keeping would-be thieves at bay.

Standout Feature

At 120 dB, the SABRE Wireless Door Alarm is very loud. For reference, 120 dB is as loud as a chainsaw and can be heard across a football field. You’ll hear it. Your neighbors will hear it. A burglar will definitely hear it.

Additional Features

  • Small, compact design is non-intrusive and blends in with most surfaces.
  • Installation is simple and each alarm comes with a self-adhesive pad. The sensor can mount on either side of the alarm, giving you more placement options.
  • The alarm has a third mode, “chime mode”, in which the sensor is still active but will only sound a chime (instead of the 120dB alarm) when triggered. This is convenient for notifying you when people are coming and going through doors, or when windows are opened or closed.
  • Battery operated (4 x LR44 button cell batteries), with a convenient battery status indicator so you’ll know when to change the batteries

Pros

A cheap, cost-effective way of securing multiple doors and windows quickly. The alarm attaches to a variety of surfaces using an adhesive pad that’s included. Chime mode is practical for letting you know whether kids are coming and going.

Drawbacks

The lack of an external status indicator requires you to manually open the cover in order to check whether the alarm is on, off or set to chime mode. This design oversight is coupled with the fact that the actual switch is pretty tiny.

Summary

SABRE’s door alarm is a good choice for those who want budget security. The affordable price and easy wireless installation means you can secure your entire home in an afternoon.

However, due to its poor design and frustratingly small on/off switch, it’s not ideal for high-traffic doors and entranceways. In these situations, you will want to be changing the status fairly often (from armed to chime or off mode) and doing so often and with ease is not practical with this unit.

GE Personal Security Door Alarm (45115)

GE makes a variety of home security devices, and this is the most affordable of the three listed in this article. Usually coming in at under $10 a pop, this tiny magnetic door alarm emits a high-pitch 120 dB squeal that last as long as the door or window it’s attached to is open.

Standout Feature

Besides the 120 dB alarm and 90 dB chime that chirps twice whenever a door or window opens, the GE Personal Security Door Alarm is significantly cheaper than other similar alarms on the market. Even at the low price, you’re still getting a quality alarm that can potentially last a long time.

Additional Features

  • Easy wireless installation against any flat surface.
  • Chime mode provides a 90 dB alarm that beeps twice when people are coming and going through doors, or when windows are opened or closed.
  • Battery operated (4 x LR44 button cell batteries) with a low battery test button to check the current battery life.
  • Includes batteries and mounting hardware.

Pros

A very loud and practical alarm for securing numerous windows and doors. Can easily be heard either inside and outside a house. It’s great for keeping track of children as well as protecting your home, and each of the alarm’s three settings—off, alarm and chime mode—are easy to access and switch between.

Drawbacks

Older doors with trims or frames make it difficult to line up the sensors correctly—both components need to be aligned within ¼ inch of each other against a flush service.

The adhesive wears down quickly, which can be frustrating if you need to make multiple adjustments to the alarm’s position only to find that it won’t stick to the adhesive anymore.

Summary

Overall, the GE Personal Security Door Alarm is a cheap way to rig your home with a “fire alarm loud” sensor. As long as you don’t have any trim around your door (or don’t mind cutting into it in order for the alarm and sensor to be flush), you’ll be able to quickly secure entrances and windows.

GE Deluxe Wireless Door Alarm (45117)

The GE Deluxe Wireless Door Alarm is a slight step up from the simpler GE Personal Security Door Alarm. Whereas that model would ring an alarm continuously if a door or window was opened, the Deluxe Wireless Door Alarm can be programmed with a small keypad to trigger a delayed alarm that will activate after 45 seconds.

Standout Feature

The GE Deluxe Wireless Door Alarm utilizes a four-digit keypad, enabling you to quickly activate and deactivate the alarm as you come and go. There’s no cover flap—just a simple four-button column that controls your settings. This gives you more flexibility with your alarm options. Activate it while you’re home to alert you instantly if there’s an intruder, or set it to a delayed mode that gives you time to leave or re-enter the code.

Additional Features

  • Two switches with four different modes:
    • Home/Chime: A simple chirp that activates whenever a door is opened.
    • Home/Alarm: Set the alarm by entering your code. The alarm will immediately go off if the door is opened, and won’t stop until your code is re-entered.
    • Away/Chime: Same function as Home/Chime.
    • Away/Alarm: Set the alarm by entering your code. The alarm will activate after 30 seconds. When returning, you have 45 seconds to enter your code before the alarm activates.
  • Flashing red and green lights show whether the alarm is active (green) or giving you time to leave and/or re-enter your code to deactivate (red).
  • Requires 3 AAA batteries.

Pros

A cheap, cost-effective way of securing multiple doors and windows quickly. The alarm attaches to a variety of surfaces using an adhesive pad that’s included. Chime mode is practical for letting you know whether kids are coming and going.

Drawbacks

Mounting the alarm can be difficult, especially on doors with trim. The keypad itself is quite noisy and could possibly reveal the location and existence of your security system to anyone in the vicinity.

Summary

GE’s Deluxe Wireless Door Alarm is ideal for single-entry homes and apartments. It’s loud enough to scare off any would-be thieves or alert your neighbors to a disturbance while your away. Although installation can be tricky if you don’t have a flat, flush surface for the alarm to attach to, the fact that it runs on common AAA batteries and offers a variety of alarm settings makes up for any shortcomings.

Doberman Security Portable Door Alarm with Flash Light

The Doberman Portable Door Alarm is a bit different than other door alarms: rather than mounting an alarm and a sensor to a door, Doberman’s alarm simply hangs from any doorknob. A metal clip is then inserted between the door and doorjamb, which triggers an alarm as soon as the door is opened.

Standout Feature

The portability of Doberman’s door alarm is ideal for travelers that want to secure their hotel rooms, rental homes, cabins, Airbnb apartments—you name it. Here’s how it works: the alarm itself hangs from a doorknob (or similar structure). Two prongs wired to the alarm are then inserted into the space between the door and the doorjamb. The alarm is triggered when the door is opened and the prongs separate from each other.

Additional Features

  • 100 dB alarm that’s loud enough to wake you up or hear from outside.
  • No tools required: Alarm body comes with a cord that wraps around doorknobs.
  • Built-in flashlight for nighttime use.
  • Uses 2 CR2032 3V lithium cell batteries (included).

Pros

Great for travelers that want peace of mind while on the road. The Doberman is extremely portable and can be applied to almost any doorway. The built-in flashlight is handy if you’re in a pinch and need a little light, or if the alarm is triggered at night and you want to see what caused it.

Drawbacks

The nature of Doberman’s portable alarm makes it ill-suited for permanent home use, since you’ll need to “reset” the alarm mechanism anytime a door is opened. You can’t leave through the same door it’s connected to, otherwise you’ll trip the alarm, so using it as an away alarm is even more difficult.

Summary

A great alarm for people who don’t need an alarm all the time, the Doberman can be used occasionally to arm important doors or while traveling to keep thieves away. Although the alarm has to be reset each time it’s triggered, it’s a small price to pay for mobile security when you’re on the go. However, because of this it’s not ideal for securing your home or apartment year-round.

LingsFire Magnetically Triggered Alarms for Doors or Windows

This 4-pack of magnetic door alarms is an affordable way to secure multiple rooms, doors and windows in one day. Each unit has a single function: to trigger an alarm that lasts as long as the connected door or window is open. While the lack of additional features may seem underwhelming, the simplicity of each alarm is great if you want no-nonsense security at a budget price.

Standout Feature

“Peel and stick” installation means all you have to do is remove the plastic from the alarm’s adhesive bottom and stick it near a door or window. Add the magnetic sensor, switch the alarm on, and you’re in business. Your whole home can be secured in a matter of hours, if not minutes.

Additional Features

  • Alarm is magnetically triggered when doors, cabinets or windows are opened.
  • Surprisingly loud 100 dB alarm in each unit.
  • Twelve LR 44/AG 13 button cell batteries included (3 for each alarm).

Pros

Simple in design and purpose, LingsFire is a pure alarm that only does one job, but does it pretty well. Since the alarms come in a 4-pack, you can secure less obvious (but equally important) entranceways, such as screen doors, garage and kitchen windows, and garden sheds.

Drawbacks

Although the alarm is quite loud, the LingsFire is made with a relatively cheap plastic shell that can break easily. The adhesive backing doesn’t always want to stick to surfaces, which could lead to a broken alarm if it unsticks from a door while you’re away.

Summary

The LingsFire is a decent starter kit for those looking to secure a variety of entrances. While it doesn’t have advanced options like a keypad, chime mode or remote control, it’s a basic alarm that will alert you when you have unwelcome guests.

GE Personal Security Door Stop Alarm

Similar to Doberman’s portable doorknob alarm, this GE door security alarm is a compact and portable alarm that’s suited for traveling. It secures any door with a pressurized lever that triggers an alarm as soon as the door begins to open. Even a slight budge will activate the 120 dB alarm.

Standout Feature

It’s a doorknob! It’s an alarm! GE’s 2-in-1 alarm is pretty useful if you need to protect your room and create a little physical resistance at the same time. Any attempt to open the door will result in a high-piercing blast of sound that will likely scare people away before they can even peek inside the room.

Additional Features

  • Compact design makes it extremely portable.
  • Rubber base pad provides traction on wood, tile, vinyl and carpet.
  • Functions as a doorstop when not being used as an alarm.
  • No wires or complicated installation.
  • Battery operated by a single 9-volt battery (not included).

Pros

Travelers will appreciate the compact design which can fit inside a jacket pocket, travel bag, carry on or suitcase. The on/off switch is toggled by pressing your foot on a pressurized button, which makes arming and disarming easy. And unlike Doberman’s portable alarm, there’s no finicky wires or prongs to mess with, just jam it under a door and switch it on.

Drawbacks

GE’s doorstop alarm only works while you’re inside the actual room—unless you have another exit route. It can only fit under doors with a big enough gap between the sill and the bottom of the door, otherwise there won’t be enough room to wedge the alarm into and anyone opening the door will just push the alarm away without triggering it.

Summary

GE’s doorstop alarm is a clever way to secure your room. It acts as both an extremely loud alarm and a physical barricade in case someone tries to force their way inside. It’s not a traditional door alarm and people can’t come and go (it can only be armed from inside a room), but it’s handy in a pinch and great for frequent traveler’s looking for a little security while on the road.
