The doorbell is used not only in apartments but also in suburban real estate, the hotel industry, trade
enterprises, warehouses, and checkpoints. For each object, you can choose different solutions: from
traditional wire samples to modern video systems. Any model will provide the primary function of “ringing
the doorbell”, but additional options, ease of installation and use play a decisive role in the choice.
In the beginning, there were bells thesparkshop.
More precisely, at first, they just knocked on the door. First, for example. Or they announced the visit by
shouting. Then they began to attach heavy rings to the doors (you probably saw such rings in historical
films) or hung a metal bar and a hammer nearby – you hit harder, and the owners will open it. At the
next round of history, bells appeared at the entrance. Alas, they were not always heard from the
inside. Then they thought of placing the bell inside, attaching an external handle to it. The guests
twisted it, forcing the firing pin to strike the bell.
Varieties of calls
The call consists of a button placed outside (usually on the wall near the entrance) and a receivingmodule
position. The main classification of devices is related to the principle of operation and installation
According to the type of information provided, models are distinguished:
Combining sound and video.
Wired bell – proven for decades
Wired calls work from the mains. This is usually attributed to the minuses – if the light is turned off,
there will be no sense from the call. The need to stretch the wire, make holes in the walls is also
considered additional trouble, although in fact connecting the call is a simple matter.
When you move into a new building, you are likely to encounter a wired bell. Developers choose them
because of their low cost. Electronic models, unlike electromechanical ones, are equipped with the
ability to select a melody and adjust the volume. Even if there is only one tune, such as birdsong or
piano sounds, it is better than the standard signal to login.
A big plus of a wired call is its reliability. Due to the simple design, it will work for more than a dozen
years. This is probably why many are in no hurry to switch to a wireless model: the device works, why
Wireless bell – a modern alternative
The most common and practical option is the classic battery-operated wireless bell. A radio transmitter
is built into the button of such devices, and a signal receiver is built into the body. When the button is
pressed, the speaker receives a radio signal and a sound is heard.
There are instances with a wireless kinetic button. She doesn’t need batteries. The kinetic energy from
pressing the key is converted into electrical energy and the button sends a signal to the receiver.
The main advantage of these products is the absence of wires. No need to pull the cable, drill the
walls. This is especially true for private houses, where the gates are located at a distance from the
entrance to the back. The button is glued or put on adhesive tape, the receiving module is placed in a
convenient place – in a closet in the hallway or in any room.
That is, the installation process is as simple as possible. Among wireless calls, there are also options in
which the receiver must be connected to the network (for example, samples powered by an outlet), but
in this case, installation is simpler than wired counterparts. So, its better to choose between the two
wisely to the techno tricks.
