What is a doorbell and how does it work?

A doorbell is a signaling device typically placed near a door to a building’s entrance. When a visitor presses a button the bell rings inside the building, alerting the occupant to the presence of the visitor. Although the first doorbells were mechanical, activated by pulling a cord connected to a bell, modern doorbells are electric, operated by a pushbutton switch. Modern doorbells often incorporate intercoms and miniature video cameras to increase security.

However, it’s the doorbell’s simplicity that makes it such a marvel. These little devices put the scientific principle of electromagnetism into action in a useful — and tuneful! — way.

The heart of a doorbell is an electromagnet. Electromagnets are coils of wire wrapped around a small piece of magnetic metal. When electricity passes through the wire, it creates a magnetic field around the wire.

When you press a doorbell button, you complete an electrical circuit that allows household electricity to flow through the doorbell’s internal electromagnet. The magnetic field generated by the electromagnet is then used to power a mechanism that creates the doorbell sound.

A simple chime doorbell uses the magnetic field created by the electromagnet to move a magnetic piston to strike two tone bars. This makes that “ding dong” sound you’ve probably heard many times.

2 Types of Doorbells

Installation and Maintenance

The electrical wiring for a wired doorbell must run through the walls. The speaker’s wires should run between the outdoor button and the indoor button/bell system. The wires run into the transformer installed next to the circuit breaker box so that the right voltage flows through the doorbell. The installation process requires you to hire a professional to properly install the doorbell.

Accommodates A Lighted Button

Hardwired doorbells (doorbells that don’t use batteries) can have a lighted button fixed on them. Putting a lighted push-button on any battery-powered doorbell will result in a shorter battery life than one that has no light.

No-interference

In wired doorbells, there is no interference with the signal range like with wireless doorbells. This is because there are no radio frequency (RF) signals transmitted through the air. The signals in a wired doorbell flow through the wires/cables.

More Decorative Options

Hard-wired doorbells come in many different styles, which allows you to choose among several designs in order to match your house décor. The designs can range from sleek wood and ornate designs to antique metallic scroll styles, and more.

Traditional Chimes

If you love traditional chime tones with a symphonic rich sound then you can go for classic doorbells. A wired doorbell allows you to get a unique chime sound for your outdoor and indoor doorbell. Once you select your unique sound, you can’t change it.

Versatility

The versatile nature of the wireless doorbell makes it easy to move the doorbell to a nice location that suits your house layout. You don’t need any wires to connect the doorbells. Therefore, you don’t need to make any changes to your house because the transmitter can be easily mounted on the wall using screws or other simple fastening devices.

Multiple Frequent Channels

The transmitter and receiver should be within a signal range of 150 to 1,000 feet. This ensures radio signals transmitted by the outdoor transmitter button on the front porch are heard in the entire house.

The wireless doorbell also has a multiple channel operation feature. This allows you to set the frequency channel such that it doesn’t interfere with your neighbour’s doorbell.

Support Several Receivers

If you have a bigger house, you need more receivers to transmit the signals throughout the whole house. You can also have portable receivers that you can bring with you in your backyard or even garage.

Wireless doorbells allow you to expand your system by adding more transmitters (push buttons) and receivers to your system. All connected wireless buttons should be compatible with each other and mostly from the same manufacturer.

Security and Integration Features

Many wireless doorbells have enhanced security features such as a video camera to capture your visitors, night vision, and Wi-Fi. With Wi-Fi, you can see, talk, and record your visitors before opening the door for them.

The integration of your wireless doorbell with mobile apps has become very popular recently. Mobile integration will be a large benefit since you can bring your mobile phone with you. This will enable you to see who is at your door from anywhere you take your phone. You can also communicate with the individual at your door through the doorbell.

LED Lights and Motion Detection

The doorbell can flash LED lights which is another key feature that is especially useful for those with hearing problems or in homes where the ambient noise level is high.

Wireless doorbells can also detect motion or sound at/on your front door. This can alert you of any burglary attempt at your home.

Making your decision about whether to have a wireless or wired doorbell depends on the key features you need for your specific use. You should also consider whether you may need to expand your system later. With an understanding of the features described so far and discussed further below, you can more effectively decide about which is the best for your home.
