Advice on wired doorbells

When choosing a new doorbell, the connection between the doorbell button and the receiver can be a factor to consider. The first question you should ask is: How do you want to connect the doorbell? If you want a wired connection, you're reading the right article. Here, you can read all about how a wired doorbell works and what the possibilities are of such doorbells.

1. How does a wired doorbell work?

In order for a doorbell to work, it needs power. Hooking up a wired doorbell can get pretty technical. A wired doorbell always uses cable. I've described 2 ways in which a wired doorbell can work below.

Existing connection

When connecting a new doorbell to your existing doorbell connection, the technical aspects aren't as relevant. In that case, the cables are already in place and the bell inside the house as well as the transformer have already been installed. Only if you want to do things differently or if the new doorbell needs a different connection does the technical bit become important.

New connection

There are 2-wire, 3-wire, and even 4-wire connections that you connect the doorbell button to. The doorbell cable connects the doorbell button to the bell inside the house. Since a doorbell doesn't use 230V, you'll need a transformer to transform high voltage into low voltage. The transformer is connected to a socket via a cable.

2. Want to speak to the person at the door?

A wired doorbell with an integrated camera ensures extra security. Via the receiver – which can be a smartphone or a wireless receiver – you'll see exactly who's at the door. You can then talk to that person directly via the two-way audio. Especially for the elderly or children, this is an extra safe way to first find out who's at the door. It lets you immediately identify unwanted visitors, so you'll only open the door for people you want to let in.

4. How do you install a wired doorbell?

Doorbell button

A wired doorbell button is powered by AC power. If there's no power outlet near the doorjamb, you'll have to pull a cable. This cable will run from the socket inside the house, via a transformer, to the outside of the house. Once you've securely attached the cable inside the doorbell button, you mount it on the doorjamb using screws.

(Wireless) receivers

There are different types of receivers. For instance, there are receivers that work on AC power and wireless receivers that you can carry with you anywhere. The receivers that work on AC power have to be plugged into a socket. The wireless receivers work on batteries and can be carried anywhere inside the house.

Extra receivers

Many doorbells can be expanded with extra receivers. The advantage of having multiple receivers in your home is that you'll hear the doorbell no matter where you are in the house. You can for instance put 1 receiver in the living room and 1 receiver in the garden on sunny summer days.
