The Best Door Alarm For 2019

Pinterest Google+

One of the best devices for improving home security  is the door alarm. If you’re wondering why this is the case, the answer is pretty obvious – this sensor will secure the entry to your home. In order to get inside your house or apartment, the burglars will have to use either the door or the windows. And if entry sensors are there, the burglar is likely to change their decision and run away.

We believe that every home should have this type of security features installed on all the doors, as well as windows. You might not share our opinion, which is why we suggest taking a look at some shocking statistics provided by the FBI:

  • There are about 2.5 million burglaries a year in the United States. Globally, that number is much, much higher.
  • Most burglaries happen between 6am and 6pm, when most people are at work.
  • Burglaries are more likely to happen during summer than any other time of the year. 
  • A home without a security system is 4 times more likely to get broken into.
  • Only 17% of US households have a working security system. 

If your home belongs to the 17% of the homes with no security system, you should know that these days such systems don’t cost too much. If you want to ensure the security of your home but still save your money, our advice is to focus on door/window sensors!

How Does a Door Alarm Sensor Work?

The most common type of entry sensors that can be used on doors and windows is the magnetic sensor. Basically, the sensor is made of two parts, which have magnets inside that attract each other. One goes on the door, the other goes on to the wall. 

The two parts need to be installed carefully in order to be very close to one another once the door is closed. Actually, they need to be close enough so that a magnetic connection between the two can be made. And once the connection is made between the two parts, your door is secured. Breaking the connection between the two by opening the door will cause the alarm to go off. 

How to Find Great Door Alarm Model?

These devices are based on a very simple principle, hence they’re not that difficult to make. And that’s why many manufacturers offer them at very attractive prices. However, simply putting two magnets together is not enough to ensure your home security. The door sensor needs to have many other features in order to be considered good. 

Main Features of Best Door Sensor Alarms

Here are some of the main things you need to pay attention to when shopping for a door/window alarm:

  • Power Source – Some door sensors are powered by batteries, others require AC power. If you decide to go with the latter option, you should know that you’ll probably need a professional to take care of the installation. 
  • Range – Many of these devices come with a remote receiver that you can keep anywhere you want. This way, you can get alarmed even if you’re not close to the door in question. For example, you can use put the sensor on the garage door and keep the receiver in your living room. This way, you’ll know if someone tries to break into your garage.  
  • Siren – Most door/window sensors, particularly cheaper ones, don’t have Wi-Fi. But, most of them have a siren that will create a loud noise if the magnetic field gets interrupted. 
  • Reliability – What’s the purpose of a home security device if it won’t work fine? You need a door/window sensors that won’t disappoint you, which is why advice is to focus only on those that are made by reputable manufacturers.
  • Price – These devices should not be too expensive, because they’re based on a fairly simple principle. On top of that, you will probably need more than just one sensor, which is why we think you should look only for those with the price of under 50 bucks. 

Best Wireless Door Alarms 2019

1. Fosmon [WaveLink] Loud Door Alarm

Top-Rated Door Sensor with 52 Ringtones

How it works is that you get a receiver that needs to be plugged in an AC outlet, as well as a transmitter and a magnetic strip that you need to place on the door. Once the magnetic field between the transmitter and the strip is broken, a signal is sent to the receiver, causing it to start ringing. 


  • Operating Range of 400 feet – The maximum distance between the sensor and the receiver is 400 feet (120 meters). This means that you can set the sensor on your main door or use it as a garage door safety sensor, while keeping the receiver with you in the bedroom. And you will have peace of mind during the night, knowing that no one can get in without being noticed. 
  • 52 Ringtones – There are 52 different tunes you can choose from. The best thing is that you can use different ringtones for different doors if you add more transmitters to the system.

  • Adjustable voice levels – Turn it to the maximum if you want it to shout the burglars away; keep the volume down if you want to find out when your children or your spouse come back home.


  • No keypad – Because there’s no keypad on the receiver, you can’t set up a password and that means that anyone who gets ahold of the receiver can turn the alarm off.
