  • Wireless range: 300 ft.
  • Transmitter dimensions: 2.0 x 2.0 x 0.5 inches

Extra features: 2-pack; Alexa and IFTTT Compatible; 1-year warranty

This smart alarm has been named the best window and door alarm on our list. It has a lot of great features and is sold as a two pack which can lead to saving money. This is a window alarm and door alarm built for the 21st century as it has modern features in mind.

The iSmartAlarm Contact Sensor is totally wireless and can be moved around to whichever door or window you wish. With a wireless range of around 300 feet, you definitely aren’t limited on where you can install your unit, and it’s pretty compact, too, so will suit pretty much any door or window.

This is technically an extension to the iSmartAlarm CubeOne, so you do need this if you’re going to run this particular alarm. It only works in the US and Canada but has a good level of reliability and works with Alexa once you’ve connected up via the hub.

Pros
  • Provides instant notifications to your phone as well as having an alarm
  • Connects to Alexa for smart home functionality
  • Wireless range of up to 300 feet which is pretty impressive
Cons
  • Only suitable for use in the US and Canada
  • Cannot be used without the iSmartAlarm CubeOne, so this needs to be purchased first

2.

Ring Alarm Contact Sensor Best Ring Door Alarm

Features
  • Type: wireless
  • Chimes: not specified
  • Wireless range: 250 ft.
  • Transmitter dimensions: 3.2 x 1 x 0.9 inches

Extra features: iOS and Android compatible; 1-year warranty and service

VIEW ON AMAZON

Ring is a company which has become known for its doorbells, and their video capability, but their service can be expanded with other products such as door alarms which can use the same sort of technology to link up to your devices.

The Ring Alarm Contact Sensors are an example of this. They work very reliably and are compatible with both iOS and Android devices, this means that you can get alerts on your phone as soon as a door is opened. They’re arguably the best door alarm system if you simply want to set one up to be compatible with your phone.

Keep in mind that if you do plan to purchase, this will only work with the Ring alarm base station. This might be worth an investment if you are planning to install a lot of these, but is an extra expense if you just need a standalone alarm.

Pros
  • This doesn’t need any tools to install, it is super easy to get up and running
  • The range is up to 250 feet
  • These alarms come with their own battery installed
  • Set it to trigger an audible alarm or just notify via your phone
Cons
  • You can’t use it without buying Ring’s own alarm base system first

  • Chimes: 1
  • Wireless range: not specified
  • Transmitter dimensions: 3 x 1.5 x 0.8 inches

Extra features: 1-year warranty; loud 120dB alerts; low battery indicator

VIEW ON AMAZON

The Noopel Door Window Alarm is a very simple and very loud option! It doesn’t have a huge amount of other benefits besides the fact that it is reliable and affordable but this is really all most of us need.

We’ve named it the best door and window alarm for Alzheimer’s patients, as it is loud enough to alert family members or carers in other rooms if the patient should get up and decide to go for a walkabout. This is a safety measure that Noopel has clearly considered. Thanks to its size, it’s also easy to take with you on trips, so you can have peace of mind wherever you go.

Another reason these are nice and safe is the fact that they have an indicator which kicks in when battery is low, this means that if you need to replace the battery then you will be able to do so long before it becomes an issue. You won’t end up with a night where you don’t have the protection of a door alarm sensor.

Pros
  • Reliable
  • Very loud, you will be able to hear this even from a distance, great if you are keeping an eye on someone
  • Low battery indicator comes on automatically
Cons
  • No smart home and smartphone compatibility
  • This is a standalone alarm

Fosmon WaveLink 51004HOM Best Door and Window Alarm for Multiple Doors/Windows

Features
  • Type: wireless
  • Chimes: 52
  • Wireless range: 400 ft.
  • Transmitter dimensions: 2.9 x 2 x 0.6 inches

Extra features: 4 volume levels; receiver can be paired with up to 10 transmitters

VIEW ON AMAZON

This door sensor alarm is great for a variety of different purposes.

It has an LCD which lights up as well as the alarm sound, so this is a wonderful choice for the people who have hearing impairments but wish to have multiple door alarms.

We say multiple because this door and window alarm can check on many different doors and transmit to the central hub, which means monitoring a number of different doors all from the same hub.

The wireless range is up to 400 feet, which is very impressive, and this can be used with 10 different transmitters at the same time. The Fosmon WaveLink 51004HOM also lets you choose between 52 different chimes. You can even set different chimes for different areas so you know which door has been opened when the alarm goes off. This makes it one of the best pool door alarms too, as you can instantly know when someone enters your pool room

Pros
  • Set multiple chimes and up to 10 different transmitters
  • Huge wireless range
  • Lights up as well as sounding an alarm
Cons
  • Sensors are a little bit cheaply made, the screws, for instance, are not the best quality

Features
  • Type: wireless
  • Chimes: 1
  • Wireless range: not specified
  • Transmitter dimensions: 5 x 4.5 x 1.2 inches

Extra features: 90-day warranty; loud 120 dB alert; low battery indicator

VIEW ON AMAZON

The GE Personal Security Window/Door Alarm may be cheap, but it is still an effective way of creating an alarm in your home to track when a door is opened such as a pool door or any other door or window in your home.

The range is not specified, but it certainly isn’t as impressive as some of the other door alarms on the list.

However, the 120 dB alarm is plenty loud enough and means you can hear this from all over your home.

As an added safety feature, this also has a low battery indicator. This means that if it is running low you can address this issue before your alarm fails.

The alarms can be bought in multi-packs and this is a way to save money, and this makes what is already a cheap alarm, even cheaper.

Be warned that the two pieces of this need to be very close together in order to work, so some doors may not be suitable – if the frame is a long way from the door itself, for instance.

Pros
  • Affordable
  • Great battery features allow you to check when it is running low
  • Compact
Cons
  • No smart compatibility
  • May not work if the door is a long distance from the frame or there is a gap

Secrui Door Chime Best Door Alarm System for a Large House

Features
  • Type: wireless
  • Chimes: 52
  • Wireless range: 500 feet
  • Transmitter dimensions: 3 x 1 x 0.6 inches

Extra features: 5 alarm volume levels; receiver can be paired with up to 20 transmitters

VIEW ON AMAZON

The Secrui Door Chime is an excellent model with some very good features, and it is designed to work even in large homes or other commercial buildings.

The features making this one of the best door chimes for windows and doors in a large space include the fact it can be paired with 20 different transmitters. On top of this, it has a wireless range of up to 500 feet which means that you can connect transmitters a long way away and they will still show on the central hub and sound the alarm.

There are lots of chimes and volume levels to choose from, and this is expandable. You can buy more transmitters the more you need, say if you start with a few and then eventually buy the full 20!

It has an LED flashing mode for the hearing impaired, too.

Pros
  • Exceptionally easy to install with a magnetic strip
  • Works with a huge number of transmitters
  • Has a variety of volumes and different chimes
Cons
  • Mute mode can be accidentally left on

HENDUN Wireless Remote Door Alarm Best Door Alarm with Remote

Features
  • Type: wireless
  • Chimes: 1
  • Wireless range: not specified
  • Transmitter dimensions: 4.1 x 2.8 x 2.4 inches

Extra features: magnetic sensor; 4 modes; comes with remotes

VIEW ON AMAZON

The HENDUN Wireless Remote Door Alarm is another very affordable option for a door alarm. Though it is cheap, it has a feature which many others don’t; the remote.

It is very loud at 105 dB of volume. You can set it either to chime as a gentle alert (when people come home, for instance) or you can set it as an alarm. It can be used in a lot of different settings including sliding doors and as a pool door alarm.

The HENDUN Wireless Remote Door Alarm is easy to install with an adhesive strip.

The chime may be a nice added feature, but be warned that it is very loud! It may not be suitable for a small home or store to tell you when someone has entered.

For the price, it is hard to argue with the features and many people love having a remote control to change the modes and turn this on and off.

Pros
  • Remote controlled
  • Loud and clear alarm
  • Easy to install
Cons
  • Range not specified
  • The chime is a nice feature, but it is very loud and volume is not adjustable

Buying Guide

If you’ve never bought a door alarm before it can be hard to know what you are looking for, and why some features are absolutely vital when getting your hands on the very best door alarms out there. Our buying guide has been created to help you to understand which features are the most important as well as the advantages, and how to get the very most out of a door and window alarm when you purchase one.

Advantages of having a door and window alarm

Top 7 Door Alarms: Keep Tabs on Your Doors and Windows at All TimesA door and window alarm has a huge amount of benefits, some of which you may not have even considered. When you first hear the term ‘door alarm’ you probably think of a device to try and stop burglars. it is true that an alarm which sounds when a burglar enters a door or window can be hugely beneficial as well as being a deterrent, there are other benefits.

  • A door alarm can be put in place on a pool door to tell you if someone walks into the pool area, this is great if you have children and you want to make sure they don’t put themselves in danger.
  • Knowing when your kids walk outside can be another big benefit of an alarm, which can also be set to chime as well as sound as an alarm (depending on which model you buy). This is also great extra peace of mind for parents of children with special needs.
  • For patients of diseases such as Alzheimer’s, who are prone to going wandering without knowing where they are going, this can be a way to alert carers when a door has been opened.
  • Shopkeepers may want to use the ‘chime’ feature on a lot of these alarms to tell them when someone has entered their store, this is great for small stores where staff may need to be vigilant and also tend to stockrooms.

Generally, the key benefits include a lot more security around the home.

Features to consider when choosing a door alarm

The following are some of the features you should think about when it is time to choose your door alarm. These are the most important features we have considered when creating our door alarm reviews.

Wired vs. wireless

Top 7 Door Alarms: Keep Tabs on Your Doors and Windows at All TimesWired technology is gradually dying in a lot of different industries and products and this is no different when it comes to door alarms. There are very few options which require a wire back to a central hub anymore, and most of the products on the market can communicate and sound an alarm wirelessly. As they tend to be battery operated, wires aren’t even used for electric.

Range

With any wireless technology, there is the issue of range. These transmitters connect to a central hub, and the range is how far from that hub they can be and still set off the alarm. The range of these alarms tends to be more than good enough for most home sizes. For instance, the Fosmon WaveLink 51004HOM can work at up to 400 feet.

It is up to you to decide how high a range you need. It is a case of matching up your building and the distance of your doors from any receiver for the door alarms.

Chime / alarm settings

As well as functioning as an alarm, most of these products can also be used as a chime. This is helpful for if you just want a little warning if someone enters your store or home, but it isn’t critical. Many allow you to choose between the chimes, and some, such as the Secrui Door Chime even allow you to set different chimes for different points in the house. This means you will know which door has been opened.

The best door and window alarms also allow you to have different settings, for instance, you may be able to choose what you want the sound to be, or the volume of the alarm or chime which is set off by the alarm.

Dimensions

The dimensions may not seem too important, but actually, if you buy a transmitter which is too big to fit in your doorway then it is rendered totally useless. The dimensions should definitely be considered if you are looking to fit in a small space such as a window, too. The alarm shouldn’t need to be big and bulky in order to do its job.

Fortunately, most of these products are pretty small. Our list doesn’t contain any which are too massive! This means you can probably fit your alarm onto the door with no issues. However, it is always worth measuring up beforehand.

Receiver transmitter capacity

Top 7 Door Alarms: Keep Tabs on Your Doors and Windows at All TimesThe main hub of your door alarm system may have the potential to connect multiple receivers. If this is the case, it will have a capacity for how many different receivers it can be linked up to. If you only need a few different transmitters on a few different doors and windows, then you can probably get away with a capacity of just a few. However, if you need a lot of receivers, for instance, in a commercial building, the Secrui Door Chime has a capacity of up to 20.

This is one of those features which is not vital for everyone. If you only need one door alarmed then you don’t need to worry.

Ease of installation

Most of the door alarms on our list are very easy to install. There are some products which require screwing in and this can be annoying and require tools, and a little bit of time to be invested. Luckily, most are now made with a double-sided adhesive tape which means you can just stick them to the wall. This means less stress and more simple installation.

Pretty much anyone can install the door alarms on our list, but some are especially simple. For instance, the Ring Alarm Contact Sensor requires no tools and can be set up and ready to go in a matter of minutes.

Extra features

Though the very basic door alarm features are obvious (being able to sound an alarm reliably) there are a lot of other features to consider, which you can have if you think them important. Many different door alarm companies are trying to create a unique offering.

Extra features can be very simple, such as a remote control like that on the HENDUN Wireless Remote Door Alarm. Other simple features include low battery alerts to tell you when you need to replace or charge the battery.

More advanced features include smart home and Alexa connectivity, IFTTT compatibility and smartphone connectivity, allowing you to get notifications on your phone.

FAQ

The answer will depend totally on your home. It is down to how many doors and windows in your home you want to monitor. If you have a big home or other building, you may want 10-20, others will find that 1-5 is enough to fit their needs.

Any door or window you wish, as long as the alarm fits. The door and window doesn’t have to be specific in its location. For instance, they’re not just made for front doors. Instead, you can install them in stores, pool rooms, garages, outbuildings and more!

This varies from one model to the next. Some of the door alarms on this list can reach up to 120 dB, which is very loud. This means they can be heard even from a distance or even wake you up if you are sleeping and there is an intruder.

Our Verdict

Top of our list is the iSmartAlarm Contact Sensor, a pretty good range of 300 feet is combined with some great features including compatibility with smartphone and smart home setups. We’ve rated it 9.9/10.

Secondly, the Ring Alarm Contact Sensor is brilliant for those already using ring products or who want notifications straight to their Apple or Android device, along with alarms and chimes. We’ve rated this an almost-perfect 9.8/10.

Third on our list is the Noopel Door and Window Alarm. Though these products don’t have the same modern connectivity, this is a great, loud and reliable alarm which offers good value-for-money, too. It is perfect if you need an alarm which can wake you up during the night! We’ve rated it 9.7/10.
