Wireless doorbells are not exactly invisible but they are a lot more convenient and reliable than their hard-wired counterparts. Apart from being easier to install, wireless doorbells also offer better performance because all you need is just a button press.
You can place the receiver anywhere in your home without worrying about electricity cables getting in your way or the receiver being misplaced while you’re on holiday.

How do wireless doorbells work?
So how do wireless doorbells work? When someone presses your doorbell, it triggers a switch which completes an electrical circuit. With the help of the bell’s transformer, the low voltage current is transformed into high voltage electricity and travels through a cable to your chime. The chime has another plunger that strikes metal bars or tubes when activated by electricity.
The number of bells in your system determines the number of chimes you will need for that particular house. The chime is wired to a receiver box, which then transmits sound through the air via radio waves to a wireless doorbell button transmitter. When someone presses the wireless doorbell button, the sender detects the radio waves on its receiver and produces sound from its chime.
To activate your wireless doorbell, you need a battery-powered transmitter that has two buttons; one to ring the chime in your house (usually labelled ‘doorbell’) and another specifically for the door outside (labelled ‘outside’). The number of additional buttons you can have depends on the system. Most wireless systems allow up to four separate buttons.
Some of the top wireless doorbell systems even have a separate remote button that can also make your wireless door chime ring in case you misplaced it or accidentally pressed it.
Wireless doorbell buttons or push buttons are just like the ones you see on a toy car. When you press them, they produce sounds which may be chimes, melodies or single ring tones. Some can be programmed to play custom messages such as “dinner’s ready” or “I’m coming.”
The receiver for wireless doorbells work and acts like a switch which connects to the doorbell button using radio frequencies. When you press the push button, the receiver picks up wireless signal and distribute it to the rest of the system to produce sounds at your front door.
Wireless doorbells come with different fixing options. Most are mounted on the wall but some others can be hooked onto doors, flagpoles or garden trees. These are more suited for people looking for a portable doorbell.
A wireless doorbell system needs two types of batteries – transmitter and receiver battery packs. The former takes 4 double A or triple A alkaline batteries while the latter needs 2 lithium button cell batteries. Lithium cells last longer than alkaline ones but they are also more expensive.
A wireless doorbell can operate on either 32, 40 or 56 channels depending on what frequency they use for communication between the push button and receiving unit. If you’ve got a home with lots of wireless devices, your doorbell may not work if it uses the same frequency as other devices.
Having 2 push button units operating on the same channel can also create problems unless they have individual addresses or channels.
Installing is a straightforward process. However, it’s critical to handle the chime box with care since the internal circuitry is extremely delicate. Wireless doorbells are available in a number of styles, including portable versions that do not require batteries and models that connect to an electricity source.
Features of Wireless Doorbells
Some wireless doorbell systems blink bright lights to notify the homeowner someone is in the door. Some incorporate video capabilities and telephony capabilities which allow the homeowner to speak directly to and view the person by the front door.
Mobile devices can alert the user when they press the transceiver or detects motion outside the house. This feature is excellent for those who expect a package, see an unexpected visitor or need reassure while out of town.
And they may also give you footage from your phone to view if it has been filmed at your front door.
For the very visually impaired, the door bell can also light up. Some wireless doorbells feature extra loud chimes which can be heard throughout the house. The best wireless doorbells are weatherproofed to protect against the elements and come in a variety of styles from indoor to outdoor or both.
Wireless Doorbells: Pros and Cons
One of the biggest advantages of wireless doorbells is that you can install them quickly. They don’t require any complicated wiring and most products come with installation guides that show you how to set up your system within minutes.
A wireless doorbell is also usually cheaper than hard-wired systems which may require rewiring or replacement of existing wiring.
The downside to wireless doorbells is that they are susceptible to radio interference, which may prevent them from working properly. They might also be affected by weather conditions or nearby devices like microwaves, cordless telephones and other appliances which have similar frequencies.
The biggest flaw with wireless doorbells is you can’t guarantee that someone is home at all times because you can’t hear them in other parts of the house.
This may leave open the potential for unwelcome visitors to ring your doorbell and not get a response, or others to take advantage of being able to enter when no one’s home and steal items.
Wireless Doorbell vs. Traditional Wired Model
The choice between wired and a wireless doorbell is a matter of personal preferences for the person using them. Wireless doorbell works generally or fits more easily with modern homes, as they are free from wires that can become tangled or get in the way. The fact that you don’t have to deal with wiring is also an advantage, as it means you don’t have to make any complicated repairs or hire a professional electrician.
However, a wireless doorbell is not suitable for everyone. If you live in a well-established home with lots of wires already installed, purchasing wireless doorbells could mean disrupting your current wiring and creating more mess than necessary. They may also be quite expensive to purchase. Wired models may be better in this case, as they don’t require any additional wires and would simply need to be plugged in like a standard electrical appliance.
In terms of sound quality, wired doorbells can typically produce crisper tones than wireless ones since they aren’t subjected to static interference from nearby electronics.
