Shopping guide

An intercom is a very useful communication system, as it is used to control access to our property. However, when investing in one it is advisable to know what features we are going to need, since there are many different models that offer various benefits. For this reason, we have prepared this guide to buy the best intercom.


When making a comparison of intercoms, it is necessary to define the type of system that we need to install. In this sense, we can classify them into two groups: audio intercoms and video intercoms. This can significantly influence the cost of the product, so it is vitally important to be clear about it before making the purchase.

The intercom is the traditional telephone, which is divided into two elements: on the one hand, there is the street panel, which includes a bell and a microphone, while a basic telephone is installed inside the house. Both devices allow two-way communication, so they have a built-in microphone and speaker. Also, it is possible to buy only the handset separately for greater savings.

For its part, the video door entry includes a camera on the street panel, as well as a screen on the monitor for the interior of the house. Therefore, it is possible to see an image in real time of the people requesting entry to the home, as well as listen to them and even record videos, store them and share them.

In general, the basic intercom is cheaper than the video intercom, but the price of the latter may vary depending on the elements included in the product. For example, there are models that incorporate two monitors that are very useful for very large or two-story houses. For this reason, you have to review all the features.


To find out how much an intercom costs, one of the most important features for users is the type of installation it requires, as this can increase the amount of investment. In this case, it will depend on the particular needs, whether at home, building or office.

The entrance panel can be flush-mounted, which provides greater security against vandalism, however, this type of installation is more invasive and requires greater investment if there is no space on the wall dedicated to the intercom bell.

In case the facade of your house has a cavity for this purpose, then it is recommended that you measure the space to embed before buying the doorman. If you want to complicate yourself less, you can choose a surface model that facilitates installation. However, it is advisable to place a visor to protect the equipment from the sun and rain, thus extending its useful life.

The element for the interior, be it an intercom or a screen, is generally surface-mounted, so this task can be carried out by DIY lovers without the need to hire a professional. Generally, telephones are universal, so they are compatible with conventional 4-wire + n systems, which are the most widely used in Spain and other countries. However, some devices come with an installation guide indicating where to connect each cable.


Although the most important thing is optimal communication between the people who are inside and those who are outside the place, some intercoms also offer other possibilities of use, so they can be adjusted to the needs of the home or business. depending on the functions it has.

In the case of the classic telephone, it can have a single opening key, which is used to activate a lock or automatic door. However, there are models that have one or two additional buttons, allowing more than one lock to be opened from the same phone. In this case, it is preferable that the buttons are on one side, to be able to open the doors without having to pick up the phone.

Video door entry systems usually include more options depending on the model. Some are wireless, so they work with WiFi and do not include a monitor, but rather send images directly to the mobile phone through an application specially designed for this purpose.

Security is also important. This is why some video door entry cameras include motion detection at different levels, therefore, they can send a notification to the user’s mobile when recording activity outside the house. In this way, they alert about possible intruders.

Frequently asked questions

Q1: How to use a doorphone?

The intercom is a relatively easy system to use, since it consists of two devices. First of all, it has a street panel that has a bell, microphone and loudspeaker. In this way, if you are outside a house and want to enter, you just have to press the button and wait for someone to answer inside the house and open the door for you. On the other hand, if you are inside your house and the telephone rings, this means that there is someone requesting entry, therefore, you should only raise the arm of the telephone and ask who is outside. When you have made sure that it is the voice of someone you know, then you can press the open key to allow their input.

Q2: How to install a doorphone?

This depends on the type of intercom you buy, however, in most houses and buildings there is already internal wiring from the facade to a point inside the house. It is important that the chosen device comes with an installation manual, so that you know exactly where you are going to connect the cables. This applies both to the street panel and to the telephone inside the house. In general, these elements are installed on the surface and some come with the necessary tools for their assembly. 

Q3: How to change an intercom for a video intercom?

There are several ways to make the change from a conventional system to one with video, but to start it is important to know what type of cabling the old one had. In general, old systems work with 4 wires + n, so there are currently some video door entry systems that have 5 wires, so as not to have to change the entire system.

In the case of the 2-wire video door entry system, it can be easy to install, however, you will need a transformer and a power supply to complete the communication system. Whatever your case, the important thing is to take advantage of the wires that the old installation has, if possible, but remember to check that they are in good condition so that there are no problems with the signal in the new camera system.

Q4: How to change the intercom door phone?

This is a simple procedure that you can do without the help of a professional, especially if you are a DIY enthusiast. First of all, it is recommended that you choose a universal phone, as this will be ready to replace the previous one, even if it was very old.

Next, you should remove the old phone making note of where each cable was connected, so that when you go to connect the new one it will be much easier and faster. If the telephone includes an assembly manual, then it is good to take into account the manufacturer’s instructions for a correct installation and better performance of the equipment.

Q5: How to fix a doorphone?

The most common failures of the door openers have to do with communication failures, so we must check all the connections to know if the device has really stopped working or if it is a minor failure. In this sense, if the telephone handset sounds very low or you definitely cannot hear the voice of the person who is speaking to the street panel, it is very likely that the spiral cable of the telephone is damaged, so you can replace it and the problem will be resolved. However, if you find that the problem is more serious, then it will be necessary to go to a specialist, since a deeper repair may have to be done.

Q6: How to put a push button on an intercom?

In an intercom system it is possible to place one or more buttons to open several locks, but these must come from the main one from the internal telephone, installing it in parallel with the door opening button. In this case, it is necessary to remove the cables from any point of the route, to cancel the opening button by means of a jumper and place a NO button on one of the cables that goes to the electric lock. Installations generally have spare cables for these purposes, so it is important to check this, as it would make the task easier. 

Q7: How does the doorphone lock work?

The main function of an intercom lock is to automatically unlock itself upon receiving a short, low intensity electrical pulse, typically 12V. By unlocking the lock, it allows the door to open momentarily. However, this is possible only if the lock does not have turns of the key. 

Q8: How to connect a buzzer to a doorphone?

Some intercoms admit the option of an adapted output to connect an additional bell, to take it to the area of ​​the house where the intercom is not heard. For this you have to place a cable from the street panel to where you want to install the buzzer. In this way, when they call, the connected telephones will ring and the bell will ring in parallel. However, some goalkeepers do not have this option.
