door and window sensors

Best window and door sensors are important when securing your home is a must, if you want to protect your property. Unfortunately, doors and windows are the weakest link in the security of your home. The FBI, in its report estimates that over 60 percent of all burglaries involve break-in through the window or the door.

A whooping majority of these crimes that involve forced entry, involve a break-in through the door. But don’t worry, you can monitor your home using the best available door and window sensors.

You might wonder why sensors instead of just bolting your door? Well sensors play a key role in alerting you to a break-in. A deadbolt or lock will just secure your home if a thief does not successfully break-in. On the other hand, a high performing sensor will allow you to monitor the door or window remotely, allowing you to trigger alarm before the break- in is successful.

You could even trigger a camera to record the person who is trying to forcibly enter your property. You can check our reviews of best performing sensors below, but first it is good to know how they work!

How Doors and Window Sensors Work

Door and window sensors come as two pieces, one fits to the frame of the door or window. The other piece is fitted on the door or window. The pieces contain either a magnetic contact or a sensor/ transmitter. These two pieces are placed in close contact depending on the specification of the manufacturer.

When a window or a door is opened, the connection between the two pieces is broken and triggers the sensor to transmit a signal to the control module. The sound that is produced due to the break in the contact depends on the settings at the control center and determines if a chime, alert or chime sound will be triggered.

More advanced settings and sensors will allow you to trigger other devices such as cameras to record what is happening near the opened window.

One key advantage of door and window sensors is that they can be mounted on any opening including cabinets, gates, windows, doors and other areas. For example, you can monitor your cabinet to reduce chances of a toddler getting in and locking themselves up

What to Consider when Buying a Door and Window Sensor

Size: when it comes to door and window sensors, size matters. Some sensors are too bulky and conspicuous. This means that a person trying to break into your home will be able to notice it before they break in allowing them to come up with a way around the sensors.

Size also matters when it comes to installation. You need a sensor that will fit into the window or door easily without taking up too much space. Some sensors are too large to be installed in windows while others are too large to be installed in cabinets. So you must consider the installation space when buying a sensor.

Compatibility: every single home comprises of several layers of protection devices working together to ensure that your house is secure. You may have multiple sensors such as motion sensors, glass break sensors, carbon monoxide sensors, temperature sensors and others that allow you to monitor all areas in your home.

Of course, these sensors are connected to a central home security system, which allows you to set each of the sensors or alarms. When selecting a door and window sensor, you want one that is compatible with your home security system or other home automation hubs such as SmartThings, Alexa, Google Assistant and IFTTT among others.

If the system is not compatible then it will be difficult benefit from the features of the sensor!

Battery Life: For any security system to work at all times, the systems should be live at all times. You do not want a sensor that has a low battery life that goes off after a short period of time as it will compromise your security.

You have to choose a sensor with long batter life but also comes with a replaceable battery or a rechargeable one. This will ensure that the sensor is live at all time even when there is a power outage. For the best sensors, go for those that guarantee a battery life of more than 6 months.

Those that offer a battery life of 5 years are quite good.

Area of Installation: sometimes one may want to install the sensor outside where it will be affected by elements. Other areas, such as cabinets will require installation of small sensors. In addition, different sensors have different gap configurations for different openings, and range from half an inch to one inch. If the gap between a window or door and frame is an inch you will have to look for sensor that allows for such a gap.

Failure to consider the gap may lead to errors, where the sensor indicates that the window is open while it is not.

Wireless or Hardwired: Window and door sensors communicate with the control panel either using wires or wirelessly. Those that use wires requires one to install wires that run from the sensor to the control panel. Such hardwired devices can be difficult to install and may require you to hire a contractor or an alarm company to install the sensors. On the other hand, wireless systems either employ radio waves or Wi-Fi to connect to the central console. One key advantage of wireless sensors is that they come pre-configured and you only have to attach them where you want them to monitor.

It is easy to install with basic technical or DIY skills. However, the coverage of the radio waves may be limited to a few feet from the control panel. If the control panel is far from the opening you want to monitor, then you need to consider the range of the sensor before buying.

Monitoring: different sensors come with different monitoring systems. For example, a wireless system can be connected to cellular communication or internet for remote monitoring. Cellular communication is tamper proof but can be affected by outages of the cellular network. On the other hand, internet allows for rich communication and automation.

Systems such as iSmartAlarm and SmartThings use internet for home automation. The best sensors are those that are compatible with such systems as they can easily be monitored, even remotely, by adding other sensors to increase protection layers.

You should note that if there is an internet outage or power outage, the systems will not work!

Warranty: generally, most door and window sensors will come with a one year warrant. You should consider the warrant period and how a company responds to complains before buying a sensor. You do not want to deal with a company with poor customer relations or one that does not allow returns or replacements.

A product whose replacements parts are sent quickly are the best as you will be able to ensure your sensors are up at all times. In addition, you might receive a defective product –defective batteries are the most common. If the company has poor customer relations or does not offer warrant on its product, then you will be left with a defective product, with no way of returning it.

Price: price is not an important factor when selecting sensors, especially since, most sensors are priced below 50 dollars, with majority being priced below 30 dollars. However, a typical home will require multiple door and window sensors. This means that you might have to buy a large number of sensors to monitor every door and window in your home. Thus, price may come as a factor.

Frequently Asked Questions

How does the sensors communicate with the home security system?

Many sensors use radio waves, Wi-Fi and cellular connection to connect to the alarm response center or the central console. Some sensors select the most efficient way to connect. However, majority will use an encrypted low power radio signals such as Z wave to communicate and will therefore not require a cellular or wireless connection.

Will the sensor go out if the power goes out or my wireless connection goes down?

This largely depends on the system. If it comes with a cellular connection backup, then it will operate if wireless connection goes out. On the other hand, power outages are not a problem with most sensors as the come with an inbuilt battery that lasts for around 5 years.

Can the sensors be connected to home automation devices such as thermostats, smart lights etc?

Yes. Most of the contemporary sensors are compatible with home security systems and home automation systems such as SmartThings
