Such a long-accessible and easy-to-use means of calling home owners, such as an intercom, is widespread not only in apartment buildings, but also in the private sector. The on-door speakerphone for a private house is practically no different from its more popular counterpart, installed on access doors in urban high-rise buildings. There are several varieties of such devices.
What are the intercoms for a private house
By type of communication, intercoms are divided into 2 groups:
1) wired;
2) radio or wireless.
In the first embodiment, all connections between the main unit and the subscriber part are made by wiring. In the second case, judging by the name, the connection between the components is formed by radio waves. Most often these are high-frequency electromagnetic waves above 2000 MHz. The benefits of radio are obvious. This is, first of all, quick commissioning and the absence of unnecessary electrical wiring and associated work costs. But there are also disadvantages. This is a limited range: from 100 m to 2 km, depending on the model, as well as the possibility of interference in adverse weather conditions.
According to the functional content of the intercoms can be:
1) only with the function of voice transmission - audio intercom;
2) with the possibility of visual inspection of guests - video intercom;
3) with an Internet connection, which makes it possible to remotely control your home.
Video on-door speakerphones and their advantages
Video on-door speakerphones, despite the high cost, are becoming increasingly popular. From the usual version, they are distinguished by the presence on the main module of the camera, and on the subscriber - monitor. The image, depending on the brand of the manufacturer and model, can be either black and white or color. Additionally, you can install motion sensors. Then, when the specified level of movement appears, it will be possible to observe the environment.
Of particular interest are multifunctional devices with the ability to connect to the Internet. Then, even while traveling or on a business trip, you can control your private home. The output of the input video signal can be transmitted not only to the subscriber’s handset monitor, but also to any other monitor, for example, to the security cabinet or simply to a home TV. There are currently no technical restrictions. The difference will only be in the total cost of equipment and related work.
The device and the main parts of the intercom
Any intercom for a private home will include:
1) the main external communication module;
2) intercom panel or panels;
3) subscriber handset or handsets;
4) communication lines.
The main communication unit is installed outside the home and has good protection against climatic and physical influences. Most often, it is embedded in a door or wall panel, but there may also be an overhead placement method. The module will always include a microphone and a speaker, as well as a camera and a variety of sensors, if provided for by the design.
The subscriber part of the intercom can have a variety of design options. At its simplest, it is a panel with a speakerphone. In a more comfortable version - a portable panel for radio communications with a neat monitor. In addition, the signal from the external unit of the intercom can go to several handsets and to places of need, for example, to the security control panel.
DIY intercom
If you have experience collecting radio circuits, you can always build a doorphone with your own hands in a private house. Radio enthusiasts have created many options for homemade circuits. Depending on the components and your experience, you can get an individual working set of intercom on the output.
If you do not want to tinker with a soldering iron and small details of electronics, there are ways to assemble a wireless intercom for a private house from ready-made blocks. Knowing the components of the product, an external module, the required number of subscriber tubes, interface devices, battery packs are purchased separately. Or you can just buy a doorphone for a private house. The kit will cost more, but will provide ease of commissioning. Most often it includes:
1) The main unit in the form of an external panel, on which a microphone and a speaker are necessarily installed, and additionally one or more video cameras and all kinds of sensors.
2) One or more control units, each of which contains an intercom, buttons for controlling lock mechanisms and a monitor, if we are talking about a video intercom.

In general, everything that is already in every man’s house. Of the materials useful tape, dowels and wiring. It remains to disclose the assembly instructions, and you can proceed. Most often, everything is described in great detail in the scheme attached to the doorphone kit. All the blocks and the color of the switched wires are drawn. Before installing the modules in the places chosen for them, it is recommended to assemble the entire circuit "on your knees" to check the operability.
Doorphone installation sequence

Finally
On-door speakerphones for a private house, as has been considered, have a large number of modifications. When selecting the necessary model, it is important to focus on functionality, quality and cost.

For example, such a feature as the ability to connect your mobile phone to the doorphone system will interest everyone.
Nowadays, a wireless intercom system for a private house is not a feature or a technical novelty. This is just one of the many technical amenities of modern reality. The lineup is becoming wider every day, and there are more and more functions and features. It remains just to make a choice.
