All About Intercoms

Here in this article, we will discuss about the three basic types of intercom: wireless, hardwired and video. This article will take you through all three types. Choosing the right intercom will make your home a more secure and stable refuge for you and your family.


Wireless intercoms are popular for a lot of reasons. Because wireless intercoms do not involve wiring, they are easy to install and therefore it doesn’t require a professional electrician to do the installation. You can put a wireless intercom right away, all by yourself, as soon as you take it out of the box.

Wireless intercoms apply radio frequencies to transmit messages. There are many types of wireless intercoms. You can get a desktop model where you would have a phone that would beep when someone is outside and trying to access your home (most of them a friend, relative or a family member). You could have a radio that will do the same thing as the phone.

Perhaps the biggest disadvantage of using wireless intercoms is that since they use radio frequencies, they tend to have interference, resulting to a poor signal. This problem depends on the distance involved as well as the quality and brand of the system.


For someone who doesn’t mind wires or who experiences a bad wireless signal, then the wired option is the one you should consider. With this option, you will usually get a door phone that will sound off when someone is outside, trying to gain entry to your home. Hardwired intercoms are still relatively cheap and sometimes they are even cheaper than wireless options.

Like the wireless type, the hardwired intercom also transmit messages from one point to another. Wireless is simple because it doesn’t require a professional installation and less wires involved. However, if you are experiencing an unstable wireless signal, a wired intercom would make a decent alternative.


Also known as a “video door phone” or “video door entry,” a video intercom has great benefits and it will add an excellent addition to your home security system. Since there’s a video involved, you’ll get a facial recognition feature that will enable you to see who is calling outside your home. Most video intercoms are wired for a more secure and reliable signal transmission.

Extra features and options

So which one of them would you choose? There are added options for both of these types. If you want a system that sends information from one point to another, then you’re good. If you want lots of sub-stations all around the house, then expect that the work is going to be extensive and the price going a few notches higher. For instance, you could have an intercom installed outside your home that will be able to transmit messages into five or more areas of the house.

If you want a hands-free option, you don’t need to pay an extra fee because there are lots of systems with the hands-free feature which comes with the unit.
