Recently, such devices have become increasingly popular. So what is the secret of such demand? The answer lies in the way the bell operates.

How to install a wireless call in an apartment with your own hands: diagram and detailed instructions

Let the doorbell not be the calling card of the house, like the front door. But it leaves some idea of its owners. Typically, doorbells are selected by a melody that is activated when the button is pressed. More sophisticated buyers pay attention to the technical characteristics of such a device. A wireless doorbell is a great way to show your guests your status and taste.

How does wireless calling work?

The operating principle of a wired call is very simple. A wire is laid from the button installed on the outside of the door and connected to the speaker, which is located inside the apartment. Electricity is connected to the speaker. When you press the bell button, the circuit is closed and the speaker is turned on, playing a melody.

Wireless calls use the same principle as their wired counterparts. But to turn on their speaker, you do not need to close the electrical circuit with the bell button. The signal from such a button is transmitted to the call receiver using radio waves. The sensor reads them and activates the speaker - a melody sounds.

Due to the absence of wires in the device configuration, the installation of wireless calls is greatly simplified. There is no need to drill holes or run a wire from the button to the bell speaker.

Wireless calls can be of two types:

The bell speakers of the first type are connected to the electrical network, and the button is battery operated,
in some models, not only the button, but also the speaker is powered by a battery. Installation of such wireless calls consists only of installing a button on the outside of the door and installing a speaker inside the apartment. However, it does not need to be connected to electricity.

Attention! When installing a wireless call, you need to consider the maximum possible distance between the button and the speaker. Depending on the materials from which the walls are made, this distance may vary.

Some wireless calls come with multiple speakers. They can be installed in different parts of the house: in the kitchen, garage, workshop, etc. - where there is a possibility of not hearing the speaker at the front door.

Setting up a wireless call

Inspection of the equipment.

Choosing a location for installation.

We unpack all the components of the call and select the place where its modules will be attached. If the “internal” parts of the call are powered by the network, you need to think about how to provide access to electricity.

You also need to select a location for the external button. Typically, wireless call manufacturers provide the buttons with double-sided tape (“Velcro”). It must be said right away that this option is not very practical. It is best to secure the bell button using self-tapping screws.

This can be done next to the doorway. If this is not possible, then a door leaf can be used for this purpose.

Installing a wireless call button.

Once you have decided on the location, you can proceed to installing the button. If it will be mounted close to the doorway on the wall, then using a hammer drill you need to make holes for the dowels. To do this, you need to select the appropriate drill diameter and drill to the desired depth. We install the button using self-tapping screws.

Installation of indoor wireless bell units.

The internal parts of the wireless bell do not need to be hung on the wall. Some modules can simply be placed on a nightstand next to the door or in the place where they will be used. If you decide to attach them to the wall, then again you will need a hammer drill.

Attention! If the internal parts of the wireless bell are powered by electrical power, they must be connected to it. To do this, you need to use the instructions. This procedure is no more complicated than connecting a regular outlet.

Functionality check.

We insert the battery into the button and check the functionality of the system. If a melody starts to sound when you press the button, then everything is installed correctly. You can use it.

Accessories for expanding functionality

Intercom with monitor
To create a reliable security system, you should add other protective equipment to the call. You can buy a set at once or assemble the entire system yourself from scratch.

Additional details include:

Video-eye. This is a device that operates on an ongoing basis or after a motion sensor reacts. The picture is transferred to a monitor or computer.
Motion Sensor. The device reacts when someone appears near the door. It can notify the hosts about the arrival of guests even before they press the button. It can also launch a video peephole or video recording.
Intercom. The assembled system is more complex and consists of cameras, a monitor, speakers, and a microphone. Some devices can send SMS to the owner, have backlighting and volume control.
Additional cameras. They allow the apartment owner to track who came to visit and make a decision about opening the door. The quality of image transmission on the screen and viewing angle directly depend on the video camera itself.

When choosing the best circuit, you need to take into account that additional parts, especially those working around the clock, need more stable power. Options are possible, for example, activating the camera at the press of a button, circuits with a motion sensor. Additional options increase the cost of the entire system.

Working principle of wireless doorbell, easy to install yourself

Wireless doorbell

Recently, such devices have become increasingly popular. So what is the secret of such demand? The answer lies in the way the bell operates.

Operating principle

To make it easier to understand how a radio call works, let’s first consider the principle of operation of a regular wired call. It consists of two parts connected to each other by a wire. The external part is a button that is installed outside the front door. The second internal part is a signal receiving device with a speaker. It is connected to the electrical network. When you press a button on an external device, a signal begins to flow through the wire to the internal device, then it is converted and sent to the speaker, resulting in a ringing sound.

The principle of operation of a wireless doorbell is similar, the only difference is that the signal from the button (transmitter) is transmitted to the internal device (receiver) via radio waves rather than wires. To do this, the transmitter and receiver have mini-antennas through which the signal is transmitted. In most modern devices of this type, the role of the antenna is performed by the circuit of the microcircuit. This allows you to make them compact.

Such wireless devices are especially popular not only among apartment owners, but also among people who have private homes. This is due to the fact that there is no need to drill walls or lay wires through the air or underground from the wicket or gate to the house. In addition, the range of such calls can be up to 150 meters, which is a definite plus.

Types of wireless doorbells

There are many different models of wireless doorbells available today. They vary in price, configuration, functionality and type of power supply, reliability and scope of application.

Models of such gadgets are presented in various configurations. They may have multiple buttons associated with a single receiver. This is useful if there are several entrances to a room or area.

Wireless call with two buttons

But there are options with several receivers operating from one button. Such receivers also have many advantages. For example, they are installed in places where a bell located near the door usually cannot be heard (kitchen, bathroom, garage, etc.).

Wireless call with two receivers

If the distance between the button and the speaker is greater than the operating range of the device, then it can be supplemented with a repeater, which will significantly increase the operating range. The principle of its operation is that it simultaneously performs the functions of a receiver and transmitter. The repeater, configured for both devices, receives the signal from the transmitter and transmits it to the receiver.

Based on the type of power source, the following main types of devices are distinguished:

The transmitter and receiver are powered by batteries or rechargeable batteries.
The transmitter is battery powered and the receiver is mains powered.
The transmitter operates by pressing (without batteries), and the receiver operates from the mains or batteries (battery).

Best models

What is a wireless call, its types, how it works and where it is used

Key Features of Wireless Calling Models

When choosing any item, first of all it is worth assessing how suitable it will be for the conditions in which it will be used. To accurately understand whether it is worth installing a wireless call at home, you need to evaluate their features in more detail:

There is no need to run wires from the button to the speaker. This is the main difference, often influencing the choice of this type of device for a private home, in which the front door is quite far from the gate and a friendly dog runs between them.

Here you can install a regular wired bell without any problems, but it is best to bury the wire underground. Otherwise, it may stand out somewhat in the yard design.

Autonomous power supply. Since wireless calls are battery-powered, when the lights go out, guests will not have to call the host from the street for a long time. This is also a determining factor for summer cottages that do not have electricity. Powered by batteries at the same time creates certain inconveniences associated with their periodic replacement, but here you have to choose what is more important.
A wireless call cannot be installed everywhere. It is necessary to look at the distance from the receiver to the transmitter and the presence of obstacles between them that impede the passage of the radio signal.
If the house has more than one door (or gate), but several, then you can purchase an electric bell with two buttons. This will significantly reduce the cost of their installation compared to wired models.

Easy installation, dismantling and transfer of the button. This feature is rarely in demand, but if you need to move the gate, change the side it opens, or install a mailbox exactly where the button is located, then it will be much easier to do this. If with a standard call you inevitably have to re-wire the wiring, then the wireless one is simply re-wired.

This may also be one of the disadvantages - some manufacturers make bell buttons with Velcro, which, if done poorly, can quickly fall off. If you are buying just such a bell, then you need to evaluate whether it is worth additionally screwing it on.

Scheme and principle of operation of wireless calls

For the average user, the principle of operation of wireless calls is very simple - the transmitter button is pressed, the radio signal from it goes to the receiver, where it activates an electrical circuit that supplies voltage to the speakers and a melody plays.

Despite the fact that the device diagram is rarely attached to it by the manufacturer, numerous radio amateurs have adopted the remote method of controlling the device itself, making not only bells with their own hands, but also various control devices - a wireless light switch or a remote garage door lifter.

The circuits of these devices are easy to manufacture and unpretentious in operation. The first two are separate boards for the button and the receiver, and the third circuit does not even require any configuration - the receiver is a regular supergenerator and, according to user reviews, everything is highly stable.

Nuances when choosing a wireless call

Like conventional models, wireless doorbells for the front door must be selected based on certain rules, especially if this is the first time purchasing such an item and there is no experience in operating such devices.

Distance

The main quality for a wireless call is the range and strength of the signal that is transmitted from the button to the speaker. If there are 5-10 meters between them, then this indicator is hardly worth paying close attention to, and when you plan to use the device at a distance of 50-150 meters, then it is better to test it before purchasing and agree with the seller about an exchange or return, if necessary This electric bell won't work anyway. This is also quite possible - after all, you cannot see with your eyes whether there are obstacles in the path of the signal or not.

How to choose a wireless doorbell for your apartment

Nowadays, many people are interested in modern wireless calls - this is a rather convenient thing, but when purchasing, you need to observe some of the features of your home. Let's look at how to choose a wireless doorbell and what its advantages are.

How does a wireless call work?

The operating principle of a simple doorbell or gatebell is based on the fact that a wire is laid from a button located outside, connecting to a speaker located inside the house, as well as to the electrical network to power the bell. When the visitor presses the button, the signal travels through the wire and the bell rings.

Wireless calls work according to a similar scheme with only one difference - the signal does not travel through a wire, but by receiving radio waves . This is much more convenient because it makes it possible to get rid of a bunch of cords, while these devices are powered by a regular battery or accumulator, which does not require installing a network near the bell location. Devices can also have a combined power supply: a battery is installed in the button, and the speaker is connected to the network in the usual way.

Attention! It should be taken into account that the range of a wireless call may be reduced depending on the type of materials from which the house is built. Brick concrete walls and steel doors partially block the signal.

In modern calling devices, you can not only select a pleasant melody from the main range, but also download any one using a flash drive or transfer it using a cell phone.

Wireless models can also be equipped with more than two speakers. In this case, you can install receivers in places in the house where the call is difficult to hear, for example, in a summer kitchen or garage. There are also devices that come with several buttons. This is especially true for those who have a house and several gates from different parts of the site.

Differences between street and apartment calls

If you decide to choose a wireless bell for your door, then you need to take into account that there are models that are intended for use in various conditions. So, for example, ordinary equipment is suitable for an apartment, but for the street you need special protection , both for the internal filling and for external parts.

First, you need to make sure that you have a protective visor for making calls outside. It will protect the device from wind, precipitation, dust and sun. At the same time, do not forget that the visor should not drown out the signal. In addition, additional protection from dust and moisture is needed for the internal parts and the button mechanism. Remember that not all models can withstand severe temperature changes, abnormal frosts or heat.

Advantages and disadvantages

Naturally, many nuances depend on the model and country of manufacture of a particular device, but we can describe a general list of advantages and disadvantages for all such products.

Advantages of wireless calls:

Ease of installation. Attaching the device is quite simple, this is due to the lack of cords.
No wires. During installation, there is no need to pull meters of wires, which is even more important when installing a bell outside.
