Wireless calling bell

How Do Wireless Doorbells Work?

Imagine you’re watching a scary movie in a dark room late at night. The main character is creeping down a quiet hallway, and you’re waiting for the monster to jump out at any moment. Suddenly, a loud banging comes from your front door, nearly giving you a heart attack.

Wouldn’t a simple ding-dong have been less abrupt? That’s where wireless doorbells come in.

Here’s your wireless doorbell guide so you can learn what they are and how they’re a good option for your home.

What Is a Wireless Doorbell?

A wireless doorbell is a type of doorbell that operates without wires or the need to connect to your home’s electricity. It includes a chime box receiver and a doorbell transmitter.

As long as it’s charged or has batteries installed, all your visitors need to do is press a button to activate the bell located inside your home. That bell can be installed anywhere, as long as there’s a strong connection with the transmitter.

Although some wireless doorbells need the receiver plugged into a wall outlet, there are some battery-operated receivers that give you more flexibility. They usually come with a customizable chime, as well.

How Doorbells Work

Wireless doorbells provide a good option for both businesses and homes. However, the transmitter’s limited range may prove an issue for larger buildings.

A standard doorbell chime system gives homeowners a range of about 150 feet. That range can diminish depending on how many walls there are between the transmitter and receiver, as well as any objects that mess with the radio signal.

There are also business doorbell chimes that have a much wider range. Some allow up to 5,000 feet covered and can be set up in different zones.

Of course, different parts are used in these systems and how they’re set up will also differ.

Parts Involved

A traditional doorbell uses wires to activate the chosen sound. Pressing the button completes a circuit that powers the mechanism.

With wireless doorbells, batteries allow the button to forgo wires. Instead of completing a circuit, a radio signal is instead sent out when the button is pressed. A receiver picks up the signal and activates its chime.

Depending on the brand, the receiver may or may not require an outlet to function.

For larger buildings, you will need multiple receivers to increase the distance the radio signal can travel. Not all doorbell systems come with the ability to use multiple receivers, so make sure you purchase the right model.

Setting It Up

Wireless doorbells are easy to install. They don’t require wiring, and they usually have a longer range compared to wired options.

If the receiver needs an external energy source, you’ll want to find a place in your home where you can easily hear it with an outlet. Receivers that use a battery can be placed wherever you’d like without that restriction.

Some doorbells come with various features such as video and audio recording. If so, you may need to download an associated app and pair it with the device. Most doorbells also allow you to change the chime to a variety of different audio clips.

Benefits of Wireless Doorbells

As previously stated, wireless doorbells don’t have to get hooked up to anything. As such, there is no cost of installation like a wired system would require.

Since the receiver isn’t hooked up to the front doorbell, you can place it anywhere in your house. If you spend most of your day in your home office, you may want the receiver closer to it, even if it means moving it away from the center of your house.

A more pricey wireless doorbell usually comes with some kind of special features to justify the price. Some options automatically video record a visitor the second they step in front of the doorbell. Others allow you to speak directly to a guest with a built-in speaker and microphone before you approach the front door.

If your doorbell does have some kind of video recording, you can rest easier when you’re away from the house. It only takes a couple of taps on the related app to see who is there and to notify the authorities if necessary.

Wireless Doorbell Tips

First of all, keep in mind where you place your doorbell’s receiver and any object between it and the transmitter. Certain materials can seriously interfere with the path of your radio waves. As a result, your receiver may not respond to the doorbell’s button.

Concrete walls with metal in them can greatly diminish the signal. Metal is difficult to penetrate and instead absorbs radio waves. Concrete is thick and is also hard to pierce through.

You’ll also run into problems if you use other devices operating on the same frequency as your wireless doorbell.

If both your transmitter and receiver run on batteries, make sure to regularly change them out. You don’t want visitors waiting at the door for a long time because the doorbell never sent a signal.

How to Find a Wireless Doorbell Store

Anyone who wants to find a wireless doorbell for your business or home should keep in mind the cost and what features they desire. A business location will likely need multiple receivers to span its larger space. A residential building that wants better security would do well with video recording options.

For the best results, look for an online retailer that specializes in wireless doorbells.

The newest option in Ring's now-expansive range of smart doorbells, the Ring Video Doorbell 4 can be used wirelessly or hardwired and features the pre-roll feature that is missing from older models. This means you can get a better view of any triggered events, with the doorbell also recording the seconds immediately before.

The same niggles we have with other Ring doorbells still exist here, such as the fact that a chime (outside of the app on your phone) must be bought separately, but we would recommend the Doorbell 4 for those looking to make their first foray into the world of Ring doorbells.

The most striking thing about the Nest Doorbell is how slim and high-end it looks.

Aside from looks, the Google Nest Doorbell Battery also impressed us with its facial recognition, package protection, and customizable motion zones, as well as how seamlessly it worked with other Nest products. The wire-free element also means you can mount it pretty much anywhere you want, from the garden gate to the back door.

Not only does Toucan offer more flexibility with compatibility with both Alexa and Google smart assistants, but it also comes with its own wireless chime.

There's also a built-in siren for greater security, and you can access 24-hours of video without a subscription. There is an extra fee to pay if you want to go further back, however. The app interface is also a little disappointing, but this unassuming doorbell makes up for it in other areas.

If you want a more affordable Ring doorbell and one that doesn’t scrimp on the connected features of the more enhanced models, the standard Ring Video Doorbell (here, we’re specifically speaking about the 2020 model) remains a great option. Like its pricier brethren, it offers 1080p video capture, Wi-Fi connectivity, and Android and iOS app support.

The main drawback for this cheaper model sits with its battery, however. While it can optionally be wired into a wall to the mains, its wireless nature relies on its internal battery. Unlike other Ring products, it can’t be removed and replaced with a backup battery, meaning that between every 6 to 12 months, you’re going to have to remove the whole doorbell and bring it inside for a charge.

The Arlo Essential Video Doorbell can either be hardwired or run on battery power, giving you more choices about how you use it. The best feature of the Arlo Essential is the ability to leave and take messages. So useful for when you're not going to be home (or when you've got your heart set on a long weekend bath), you can leave a quick voice note for any visitors or delivery people to tell them where to leave a package.

Arlo has also built a siren into the doorbell, which it boasts over the ranges from Ring or Google. You can either set this to activate automatically or manually through the app. Arlo Secure (free for 3 months, then about $3/m) also gets you cloud recording, advanced object detection, and custom activity zones.

How we test the best wireless doorbells

The products chosen for this guide have all been tested by our writers and editors, all with decades of experience between them. Unless otherwise stated, all of the products recommended by us have been independently reviewed in real-home environments to ensure that our readers are getting the most honest, relevant information possible. Where possible, links to more in-depth reviews are also provided, so you can read more about what we thought during the testing process.

The best wireless doorbells are chosen based on various criteria, including their affordability, video quality, ease of setup and use, app performance, compatibility with wider smart home systems, and more.

How to choose the best wireless doorbell for your home

Will my wireless doorbell work with Alexa/Google Home?

Compatibility with your smart home hub will depend on the wireless doorbell you buy, but, generally speaking, Ring doorbells will always work with Amazon Alexa smart speakers and displays. The same goes for Ring Alarms and other security products, as they all come under the same banner.

Similarly, Nest products come from Google and so will work well with a Google-branded doorbell. Anything else will vary, so it's important to check before buying.

Once set up, we absolutely love how some of the best wireless doorbells work with smart displays such as the Echo Show or Nest Hub, allowing you to see what's going on outside from the comfort of your kitchen or bedroom. For more on this, take a look at our guide to the best smart speakers.

Are video doorbells safe?

Many are concerned - and for a good reason - about the security implications of essentially strapping a surveillance device to the front of your home, but there are many protections in place preventing things from getting dystopian.

We would recommend going for a well-known brand so as not to fall foul of a device that's more vulnerable to hackers, set a strong password when signing up, always download software updates when they are released, and make sure all settings are correct for your needs.

All this said smart doorbells could actually form an essential part of a home security system, adding an affordable camera that can detect motion and send alerts directly to your device when something untoward is going on.

Are wireless doorbells worth it?

Whether you opt for a chime-only doorbell or a smart video doorbell that doubles as a security device, you may be wondering whether investing in a wireless doorbell is actually worth it? After all, a traditional ringer has served you well up to this point.

Wireless doorbells offer convenience, first and foremost, allowing you to place your device pretty much anywhere (as long as it's within the vicinity of your Wi-Fi signal or indoor chime). This, combined with the smarts of modern releases from the likes of Google and Ring, makes the best wireless doorbells an affordable way to incorporate your front door into a wider smart home system.

Wireless doorbell: how to choose

What to look for when choosing

Today, many people are interested in modern wireless doorbells - this is a very convenient thing, but certain conditions for your home must be met when buying. Let's see how to choose the right wireless call and what are its main advantages.

The principle of operation of a wireless bell is based on the transmission of a signal using radio waves

The principle of operation of the device

The principle of operation of a conventional doorbell is based on the fact that a wire is drawn from a button located outside, which is connected to a speaker located inside the home, as well as to the mains to power the device. As soon as the guest presses the button, the signal is transmitted through the wire and the bell sounds.

Wireless calls operate on a similar principle with only one difference - the signal is not transmitted via cable, but by receiving radio waves from a button. This is much more convenient, as it allows you to get rid of a bunch of wires, moreover, such devices are powered by a battery or a simple battery, which does not require a network near the location of the call. Some models have a combined power supply principle: a battery is inserted into the button, and the speaker is connected to the network in the usual way. The signal is given when the button is pressed. The speaker is equipped with a receiver that responds to the sent waves and reproduces a sound, notifying the owners of the house that they have come to them.

Please note that the range of the device may be reduced depending on the type of materials used in the construction of the house. Concrete and brick walls, as well as metal doors, partially jam the signal.

How wired and wireless doorbells work

In modern doorbell models, you can not only choose a very pleasant melody from the basic assortment, but also upload any other one using a flash card and a computer, or transfer it via a mobile phone.

Some wireless bells may have two or more speakers. In this case, you can place the receivers in those corners of the house where the call is often hard to hear, such as in the workshop or in the kitchen. There are also models that include several buttons in the kit. This is a great option for those who have a private house with several entrances from different sides of the site.

Differences between indoor and outdoor models

If you want to choose a similar bell for your door, please note that there are models designed for use in different conditions. So, for example, the usual type of device is suitable for an apartment, but special protection is required for the street, both in terms of external parts and internal filling.

First of all, you need to check the presence of a protective visor for outdoor models. It will protect the button from precipitation, wind, sun and dust. At the same time, please note that the visor should not jam the signal. In addition, additional protection against moisture and dust is required for internal parts and the pressing mechanism. Also keep in mind that not every model will withstand sudden changes in temperature, abnormal heat or severe frosts.

Different types of doorbell models depending on the conditions of use

For protection against vandals for outdoor products, it is planned to equip the button with a more durable housing, a metal button instead of the standard plastic one, as well as additional safety mechanisms. Of course, such calls are somewhat more expensive than ordinary apartment calls.

Advantages and disadvantages

When the main differences between wireless and standard electric models have already become clear, you should pay attention to the advantages and disadvantages of such products. Of course, many of the nuances depend on the brand and country of origin of a particular device, but you can derive a general list of pros and cons for all such products.

Advantages of wireless doorbell models:

No wires. When installing, you do not need to pull meters of cable, which is especially important when using a bell for the street. You do not need to drill walls, hide wires, spoil the look of the interior. The power supply is mainly autonomous and does not depend on the availability of electricity.
Easy to install. Fixing the device is very easy, which is directly related to the lack of wires.
Ease of use. The call is convenient for both visitors and owners of the house.
Ability to use complex kits. You can purchase additional accessories, as well as a complex set to place several buttons and speakers in different parts of the house.
Reversible. If there is such a need, you can easily change the location of any part of the device without any hassle.
Attractive design. You can choose a model that is optimal in color and shape, with a body made of almost any material. At the same time, it will not spoil the general appearance of the room or the entrance to the house.

The main and main advantage of a wireless call is the absence of wires

We must not forget about the presence of certain disadvantages, but this does not mean at all that all devices of this kind have such negative characteristics. Usually such features are characteristic of cheap low-quality models.

Disadvantages of wireless doorbell models:

Poor fastening. This is especially true for Velcro models. With rough handling, adverse conditions, or simply due to wear or poor-quality sticky coating, the device may fall from a height and receive serious damage, up to a complete breakdown of the case and internal filling.
Frequent battery replacement. Some wireless calls are powered entirely by batteries, and the power consumption is quite significant. It is necessary to constantly monitor the presence of a charge in the device and carry out timely replacement, which can result in an extra amount of expenses for the family budget.
Jam. If moisture and dust get in, severe frost, as well as when the contacts are displaced, the button may jam and ring spontaneously or not work at all.
No signal. Such a defect is possible in case of deterioration in the quality of perception of the signal from the button, as well as due to failures in the mechanism. Then the button may indicate that the signal has been given, but the sound will not actually be played.
Easy to steal. Since the button is not connected to the wires, it will be easy to remove it for the purpose of theft or banal vandalism.

To minimize the number of possible disadvantages, it is necessary to approach the issue of choosing a product with great responsibility.

Additional accessories

In order to make your stay at home as comfortable as possible, you can additionally equip the doorbell with various kinds of auxiliary devices. They can be included in a set of more expensive and technically advanced models or sold separately. In this case, it is necessary to clarify the compatibility of devices with each other.

These accessories primarily include the following devices:

Camera . In other words, video peephole. It can work constantly or be activated when a person approaches the door. There are also models that are fully interconnected with the call and turn on when the call button is pressed. The image is displayed on the screen of the monitor included in the kit, or can be fed to a tablet, computer, smartphone, etc.
Motion sensor . This feature allows you to be alerted to visitors even before the button is pressed. Also, if there is a video eye, it activates the camera and starts recording.
Intercom . This is an integral system consisting of a call button that sends a signal to the apartment and a receiver. Also available are speakers and a built-in microphone, which allows you to communicate with the owners of the house and visitors to each other. Can be equipped with a camera.

Wireless bell can be optionally equipped with a camera and motion sensor

It is also worth paying attention to a number of additional features that some wireless calls have. They can be equipped with a backlight, a volume control key or a complete signal mute, a melody selection function and setting different signals for each individual button if there are several outputs. Some models can send home owners a signal about the arrival of guests via SMS. Each additional function increases the final cost of the product.

Bell setting

In order to subsequently avoid problems with the installation of one or another model of the bell on the door, you should make sure in advance that the principle of its fastening completely suits you. Regarding this issue, the following options are possible:

Door. If it is very difficult to screw a screw into the wall or Velcro does not stick to its finish, you can fix the bell on the door leaf itself.
Near the entrance. Most often, the button is attached to the platbands or a little further on the wall, to the side of the opening.
Gate. This is an option for street models in private homes. Be sure to choose such an arrangement for the device in order to protect it as much as possible from rain, sun and other negative environmental influences.

As for the parts that are installed inside the house, that is, speakers and a screen with a video camera, they can be fixed in almost any place convenient for you. Usually they are located near the door in the corridor, as well as in those rooms in which you often stay, but the sound from the central bell does not reach there. For the private sector, it is relevant to place an additional speaker in the workshop, basement, attic, and also outside the house if you like to spend time outdoors or often take care of the garden.

It is most convenient to fix the bell next to the front door

You can later change the location of the device. It also remains possible to convert it to a standard electric one by connecting wires and power to it from the mains.

The principle of installation itself can be based on installing the device with Velcro, ordinary double-sided tape or screws. The first option is suitable for lightweight, simple house models. For the street, as well as in order to ensure greater reliability of fixation, it is better to use screws. They can be screwed into special holes in the body of the device elements, and can also be used to install a stand or bell hanger.

What you should pay attention to when choosing

In order to choose the most suitable model and not make a mistake in the quality when buying a bell, you should pay attention to the following important points:

Device type. Wireless calls can be different, despite the general principle of operation.
Appearance and design. These are the color and type of case, shape and decoration.
Number of required batteries and their type. In the future, this will affect the cost of your funds to ensure the operation of the call.
Signal reception radius. If the size of your home is significant, you need to choose more powerful models and take into account possible barriers to signal transmission.
Melody. Pleasant sound with the ability to replace it or record your own melody is ideal.
The quality of the body materials. Plastic can crumble under the influence of external factors, this must also be taken into account.
Complete set. Check if the kit includes additional speakers, a video peephole and other useful gadgets. If not, find out if this bell model will be compatible with such devices and if they can be purchased separately.
Availability of additional functions. Not always some functions are useful for a particular buyer, so it makes no sense to overpay for their presence.
Country of origin and firm. The reputation of the company and brand is also of considerable importance. So you are less likely to purchase a low-quality product. Beware of fakes.
Mounting type. Decide what suits you best: Velcro or screws.
Warranty terms and conditions. This is a required item. The longer the warranty period, the higher the chances that the call will serve you for a long time. In addition, it is important that you have the possibility of service in the event of a product breakdown.

When choosing a wireless bell, be sure to pay attention to the signal reception range and the quality of the body materials

You can buy wireless bells from both domestic and foreign companies. Italian and German brands are of the highest quality, but their cost is quite high. There are also good Polish samples for a more reasonable price. You can also find quality Chinese products.

Pay attention to the number of batteries required for power supply. Cheap goods are likely to either be excessively energy intensive or fail quickly for technical reasons.
