What is a wireless call, device, operating principle, how to choose

In order to announce the arrival of guests to the hosts, many ways have been invented nowadays. For example, you can shout, knock on the gate, or dial a phone number. But, even taking into account these various options, there is a much simpler and more convenient way - install a bell on the gate. They come in different variations and operating principles. This must be taken into account when choosing a call and installing it yourself.

Gate

What it is, scope of application

A wireless call is a device consisting of a group of elements:

1. SPEAKER A sound comes from it when the contacts close.
2. BUTTON. This is a mechanical element that ensures the product operates.
3. TRANSMITTER. With the help of this element, a signal is transmitted from the button (located outside) to the speaker (mounted indoors and emits sound).

Wireless calls are used in the following cases:

1. For a private home (for example, when the gate is located at a distance from a residential building).
2. For a dacha where the entrance to the site is distant from the building on the site.
3. On the door to the apartment. The option with a wireless call is convenient for ease of installation, the ability to avoid drilling holes and laying wires.
4. In warehouses and offices. Giving a sound signal allows employees to be informed of the client’s arrival.

The scope of application is very wide. The wireless bell can be used wherever notification of the arrival of a guest or visitor may be useful.

Types of doorbells to an apartment or to the gate of a house

Doorbells come in a wide range. The devices differ in operating principle, design, connection option, functionality and cost. Based on the connection option, doorbells for the home can be mechanical, electromechanical and electrical. The first type of device was used in ancient times. Such a call was presented in the form of a bell that was hung inside the house on a cord. The other end of the rope was brought out. This element is also a decorative decoration for the hallway.

Modern doorbells can be wired or wireless

The bell made a sound when the free end of the rope was pressed or when the front door was opened. This option can still be found today on the gates of houses decorated in retro style, which are framed by a low fence.

An advanced device is the electromechanical doorbell. It has a simple design, which includes a signal button installed outside the home, a resonator located inside the room, and an electrical cable connecting these two elements.

The resonator is represented by a coil that has a wire winding, which can be seen in the doorbell diagram. When voltage is applied to it, an alternating electromagnetic field appears. This causes the metal hammer to vibrate and strike the metal bowl. This action is accompanied by a characteristic sound.

The resonator coil may contain a core that will perform reciprocating movements under the influence of an electromagnetic field, striking the plates on both sides, which will be accompanied by a characteristic sound.

By type of connection, calls can be electrical, mechanical and electromechanical

For such a call one or two buttons can be used. The second option for installing a doorbell is used if it is necessary to send a signal from different places. For example, from the front door and gate in a private house, at the entrance and door of an apartment in a multi-storey cottage.

Important! The buttons work independently of each other; pressing any of them closes the circuit.

Advantages and disadvantages

Before purchasing a wireless call, it is important to study its features, evaluate the pros and cons, and then decide on the possibility of use.

Advantages:

1. No wires. During the installation process, you can do without a drill (except for the case of attaching the button using self-tapping screws), pulling wires or cables connecting the button and the speaker. This is convenient when the product is purchased for a summer house or private home. When installed on an apartment door, you can avoid tearing off wallpaper or damaging the interior. The device is self-powered, so there is no need for a separate voltage supply (except in some cases).
2. Easy and fast installation. Fixing the product takes a few minutes. This is due to the absence of wires and complex fastenings.
3. Convenience. The use of such a product does not cause difficulties, both for guests and for owners of the house (cottage, apartment).
4. Easy to move to another place. Due to the absence of wires, the wireless call can be reset at any time.
5. Possibility of use in combination with complex devices. Wireless calls can be used for intercom or equipped with two buttons (if necessary).
6. Nice design. Modern models have an attractive appearance, so they fit into any interior. A large selection of models allows you to choose a product that matches the shape, color or material of manufacture. You can be sure that a wireless call will only decorate your interior or exterior.
7. Independent nutrition. Regular bells operate without batteries and require wires to supply voltage. In the case of a wireless device, this is not necessary. The voltage is supplied from batteries, so even if the lights are turned off, guests will be able to notify of their arrival. This feature is useful for private homes or for summer cottages where there is no electricity. An alternative option is to use a wireless call without batteries, when power is supplied from special batteries (purchased separately).
8. Possibility of additional equipment. If desired, wireless calls can be supplemented with other devices (depending on the model). We are talking about connecting a video camera, TV or other equipment.

Flaws:

1. Installing a wireless button is not possible in all cases. No wires are used during the installation process, and the signal is transmitted wirelessly. If there are obstacles in its path, the product will not work. Under such circumstances, you will have to install a classic wired bell or eliminate the cause of the interference (if possible).
2. The need to change the battery. The autonomous power supply tends to discharge, so from time to time it requires replacement. If you skip this point, the wireless call will not work.
3. Poor fastening. Some models are fixed with a sticky base. This option is suitable for a door to an apartment. When installed in a country house or used for a private home, the button is fixed on the street. When exposed to cold, it often disappears. In addition, the Velcro fastener does not withstand even light physical impact.
4. Possibility of jamming. The presence of negative influences (for example, moisture entering the product, the influence of low temperatures, or displacement of the contact group) leads to the button getting stuck in the actuated position. As a result, the call works until the battery runs out or the defect is eliminated.
5. Ease of theft. The wireless bell model is easier to steal because there are no wires connected to it. To prevent theft, you can install a video camera at the entrance. It will be doubly useful. Firstly, it allows you to look at the guest personally, and secondly, it will reduce the likelihood of theft.
6. No signal transmission. Problems with the circuitry may result in difficulty sending the signal from the button to the bell. Another situation is possible when the command arrives, but there is no sound.

A wireless call is not a perfect device, but its advantages more than cover the disadvantages of its operation.

Non-standard equipment

In some cases, two buttons or two blocks with calls are required. If two buttons are needed, they are connected in parallel.

How to connect two buttons to one doorbell

In practice, this means that the phase comes to the first button, and the wire that goes to the second button is connected to the same contact. From the second contact of button No. 2, the conductor goes to the free contact of button No. 1, and then goes to the doorbell.

It is advisable to find the wire connecting the two buttons in the same color as what comes from the junction box. You can do something else, but not blue or yellow-green. That's it, you know how to connect a bell in an apartment with two buttons.

In other situations, you need to connect two calls. This is often necessary when installing an electric bell in a private home. For example, one in the house, the second on the street or on different floors, in two different wings of the house, in the summer kitchen. In general, there are many options.

Among the wireless doorbells there are such kits - they have two bells and they are tuned to the same frequency, so you just need to install them in the right places. With wired ones you will have to tinker - pull the wires. In this case, calls are connected in parallel.

how to connect a bell in an apartment or house with two bells

The electrical connection occurs in the same way as described above. The phase from the button goes to one call, and from it goes to the second. A neutral wire from the junction box is connected to the free contacts of one and the other bell.

Operating principle, diagram

In the case of a wired call, the situation is clear. After attaching the button on the outside and the bell on the inside, they are connected using a wire. Power is supplied to the speaker, and the circuit is closed through a button.

In a wireless call situation, the same principle is used, but there is no need to complete the electrical circuit.

The operating principle is simple:

1. The guest presses a button installed near the apartment, on the gate near a private house (dacha) or in another place.
2. The transmitter is activated, sending the signal wirelessly to the receiver (call).
3. The electrical circuit is activated.
4. Power is supplied to the speakers and the music (that is programmed into the device) plays.

Models with a combined operating principle are available for sale. For example, the button is powered by a battery, and the sound source is connected to a standard power supply.

The speed of signal transmission and its strength depend on a number of factors - the distance between devices and the presence of obstacles (for example, walls or doors). It is important to remember that brick, concrete or metal structures significantly degrade the signal.

The design of wireless calls is simple, which guarantees their reliability, ease of operation and long service life.

There are two boards installed in the button and the device with the bell. A third circuit (signal generator) is also provided, characterized by the absence of failures.

Types and types of doorbells

Doorbells come in two types: wired and wireless. You can also name such designs as retro devices, original “hammers”, repeated signals, bells with cords. Today, these latter varieties are practically not used and are relegated to the category of rare mechanisms.

Wired calls. Such designs are distinguished by a high degree of reliability, long service life, and weather conditions do not affect the service life.

• Wired calls operate from the network (220 V). The button is connected to the bell body by a two-core insulated wire.
• Wireless type of calls. Such structures do not require electricity; there is no need for various devices to connect them.
• The operating principle of this model is the activation of a radio signal.
• A wireless doorbell can only transmit an audio signal over short distances. In bad weather it may be completely absent.

It is worth paying attention to other types of door alarm devices.

Device types

There are two types of wireless calls:

1. With separate power supply. The button runs on a battery, and the bell runs on mains power.

2. With shared meals. In this case, both nodes operate from a DC source (battery).

Modern models are divided into:

1. By functional purpose. Products can be intended for a home or cottage (street and waterproof version), for an apartment door or for an intercom.
2. According to the configuration. Buyers have several configuration options at their disposal in terms of the number of buttons and speakers - 1+1, 2+1, 1+2 or 2+2, respectively. When choosing an option, it is important to focus on the number of entrances and the area of ​​the house.

3. According to the functional “filling”. Modern models can be supplemented with Wi-Fi, a microphone, a video camera, and work without batteries. Some wireless calls have the option to set your own ringtone (using a flash drive). For better sound quality, a number of devices are equipped with two speakers (as noted in the package). This is convenient when the product is installed in a room with a large area. The device can be used with Smart Home systems (the website has a separate section on this topic).

Thanks to this classification, there are no difficulties in choosing the appropriate button. The main thing is to select a model taking into account the current situation and needs.

Technical characteristics - main differences

Despite their apparent simplicity, wireless calls differ in technical characteristics. Basic parameters that are important to pay attention to when choosing include:

1. Device operating frequency and range.
2. Type of signal being transmitted.
3. Number of speakers and buttons included.
4. Power and type of electrical power (mains or batteries).
5. Backlight (provided or not provided).
6. Possibility of installing different melodies or setting your own music (using a flash drive).
7. Volume control option.
8. Supports application function for intercom or video peephole.
9. Option to send SMS messages.
10. Night light function and motion sensor.
11. Operating temperature range (important when installing the button outdoors).
12. Availability of moisture protection (provided for outdoor options).
13. Other characteristics.

As a rule, modern wireless calling models operate at frequencies from 433 to 434 MHz. The exception is products operating at a lower frequency - 315 MHz.

When assessing the range, it is important to evaluate not only the information from the passport, but also the presence of interference. Their presence reduces the range of action. For example, a concrete wall or an armored door prevents the signal from entering. Drywall or wood transmits electromagnetic waves better.

Additional components to expand functionality

To increase comfort and convenience, you can complement the wireless call with additional devices. Sometimes they are included with more expensive models.

An alternative option is to purchase the product separately and then connect it to the “base”. In the latter situation, it is important to clarify the possibility of unification.

Additional elements include:

1. VIDEO-EYE. It operates on a permanent basis or is activated using a motion sensor (when a person approaches the door). There are cameras connected to the bell button and only activated when it is pressed. The image received from the video eye is transmitted to a special monitor. The signal can be output to a phone, PC or laptop.

2. MOTION SENSOR. The presence of such a node allows you to inform the owner about the arrival of a guest before he presses the button. In addition, the triggering of the sensor gives a command for the video eye to operate or starts recording (depending on the setting).

3. INTERCOM. Some models of wireless calls are available for intercom. Such a system is more complex and involves the presence of speakers, a microphone, a camera and a monitor that allow you to see and communicate with the visitor.

Advanced models can be equipped with backlighting, a volume control knob, or a mute button.

Some devices can send a signal about a guest's arrival via SMS. It is important to note that the price of the selected model depends on the number of additional functions.

Additional equipment

To make receiving guests even more convenient, you can purchase additional equipment for the call. They can be either included in an expensive set or sold separately. In the second case, it is necessary to find out whether the devices are compatible with each other or not. Most often, additional equipment includes:

1. Intercom. Usually this is a solid system that has its own call button. The button also sends a signal to the receiver. Naturally, the kit includes a microphone and speakers. It happens that the camera is still running.
2. Camera or video peephole. It can turn on when a person approaches or function continuously. The image from the camera can be sent to various devices - monitor, phone, tablet.
3. Motion Sensor. This device helps to know about the approach of a person in advance. If the kit includes a camera, the sensor will activate it.

In addition, there are smaller functions: device lighting, melody selection, setting a separate melody for each button if there are several entrances to the house. Some calls can send SMS to the owner's phone. It is worth remembering that the more functions, the more expensive the device.

Video eye for wireless calling

With the help of an additional camera, the owner of an apartment, house or cottage can see a visitor from a distance. As a result, it is easier for him to make a decision about opening the doors.

If there is a peephole with a camera on the apartment door or gate, the calling visitor is reflected on the monitor inside the building. The image from the camera can be transferred to a separate display, PC or laptop (depending on the selected model). The quality of image transmission depends on the camera installed in the video eye.

When choosing a circuit, it is important to consider that the peephole needs additional and more reliable power. The following paths are available here:

1. Search for a suitable low-power kit (if continuous video recording is required).
2. Scheme with video eye activation only when a button is pressed. Under such circumstances, the camera only records the face of the person calling.
3. The video eye is powered separately. In such cases, the use of a wireless call is not entirely clear, but such a scheme is common.
4. A circuit with a motion sensor that detects whether a guest is near the bell button. This option is convenient for controlling inappropriate citizens who may make fun of the owner. The convenience is that the video camera records when there is movement near the entrance (pressing the button is not necessary).

When choosing a video eye, it is important to pay attention to the camera resolution. The higher this parameter, the better the image.

On the other hand, with a higher resolution, the volume of video received increases greatly. In addition, high-resolution video eyes have high power requirements.

What is the difference between indoor and outdoor wireless calls?

When buying a wireless bell for your home, it is important to consider its future location. There are two basic options here - indoors (for an apartment) or outdoors (for a home or cottage).

In the first case, it is enough to buy a simple model, without moisture protection and a wide temperature range. If you plan to install a wireless call outdoors, the approach to selection is more serious.

The main requirement is the presence of a moisture-proof coating to prevent moisture from entering the internal elements of the device.

In addition, a wireless bell for outdoor installation must withstand temperature changes and operate in a wide temperature range. This requirement applies not only to the shell, but also to the internal circuits of the product. Moisture protection should also be provided here.

When installing on doors, it is worth providing a small canopy to protect the product from moisture, sun rays, dust, wind and other negative influences.

The main requirement is that the additional element does not interfere with the passage of the signal.

To avoid theft or protect your wireless call from vandals, it is recommended to choose models made of durable metal. The downside is that they will be more expensive.

Doorbell Feature

1. Most of these devices are easy and quick to install.
2. The devices are equipped with built-in components (camera, microphones, speakers).
3. Lightweight and easy to use.
4. You can open the door from different parts of the world.
5. It is possible not only to see who came, but also, if necessary, to record the identity of the person who came.
6. The combination of a smart bell and a smart lock is a guarantee of peace of mind for the home owner.

A few years ago, purchasing a doorbell was much easier than it is today. Because the range of these products was insignificant and the main criteria were cost, as well as size, color, and manufacturer.

The modern market offers a fairly wide range of doorbells, differing in many respects.

The distinguishing characteristics are:

• Ways of eating;
• Installation principles;
• Types of ringtones;
• Volume range;
• Design.

We should not forget that a specific type of call has individual characteristics, advantages and weaknesses.

Features of choice

When purchasing a wireless call, it is important to know the selection rules and follow them when selecting a device. It is important to pay attention to the following details:

1. TYPE. The operating principle of wireless calls is almost the same. The differences relate only to design, functionality and equipment.
2. APPEARANCE. When choosing, it is important to focus on the design of the house, apartment or cottage, so that the installed equipment fits into the interior. It is important to take into account color, design, shape and other features. Against the backdrop of competition, each manufacturer tries to distinguish its models and make them better than those of competitors.

3. NUMBER OF BATTERIES. Depending on the complexity and design of the device, the number and type of power supplies used may vary. This point must be taken into account, because in the future the batteries will have to be changed.
4. RADIUS OF ACTION. When purchasing a wireless call for an apartment, this factor does not matter. It’s a different matter when installation is planned in a private house or country house, and the distance between the gate and the house is up to ten meters or more. When studying range, it is important to consider interference in the signal path. range, without obstacles such as walls or doors. That's why it's better to focus on a larger range of action (take it with a reserve).
5. CASING. When installing externally, you should pay attention to the material and build quality of the housing. Key factors are resistance to moisture and dust, as well as vandalism. As noted, metal models with high-quality moisture protection are more suitable for outdoor installation.
6. MELODY. Most simple models have one or two melodies that you will want to change over time. That's why it's better to get wireless calls with music replacement options. Some devices allow you to insert a flash drive or transfer music from a smartphone.
7. SIGNAL POWER. When installing a wireless call button at a distance of 50 meters or more, it is recommended to take equipment with an amplified signal. In addition, before making a purchase, it is worth testing the product at the distance of interest.
8. EQUIPMENT. An equally important selection criterion is the composition of the kit. The extended version can add a video eye, an additional button or speakers, a motion sensor or other devices. When purchasing elements separately, it is important to clarify the possibility of their combined use.
9. ATTACHMENT METHOD. This is a key point that receives little attention. As a rule, fixation is achieved using simple Velcro. Under the influence of cold or other negative natural factors, it stops holding the button and comes unstuck. The best solution is to secure the wireless call button using self-tapping screws, but such an option must be provided for this.
10. PRICE. The seller’s task is to earn as much as possible from the client, so when choosing, you should not follow the seller’s advice 100%. It is important to focus on personal needs and take equipment based on your goals. You shouldn’t overpay for additional features that will never be useful, or for a brand.
11. GUARANTEE PERIOD. When choosing a simple model, the likelihood of breakdown is minimal (this is due to the absence of complex elements). It's another matter when the package includes many additional devices. Under such circumstances, you should give preference to products with a warranty of 10 years or more.

Using the above recommendations will allow you to choose a high-quality wireless call with the necessary functionality and at an affordable price.

The user is offered up to 389 melodies with the ability to set one of three volume levels. The special feature of Proline HT-W4U02 is the conversion of kinetic energy. The moment the button is pressed, mechanical pressure is converted into energy. Next, a special module sends the signal to a distance of up to 80 m before the call. The latter is connected to 5V power via a USB port. Immediately after this, the selected melody sounds.

1. Proline HT-W4U01 is an equally popular wireless call that works on the same principle. Its range is limited to 80 meters, and the number of melodies is 38 (three volume levels). Operating frequency - 433 MHz.

The absence of a power source on the button eliminates the need for batteries and saves money on their purchase. Moreover, wireless devices without batteries are more reliable. They are unpretentious to different weather conditions and are not afraid of contact oxidation.

Installation features

Installing a wireless call is not difficult, so you don’t need to call a paid technician to solve the problem. Problems are only possible when connecting additional elements, for example, a camera, motion sensor and others. In other cases, problems are excluded.

When choosing an option, it is important to take into account that it is easier to attach Velcro, but then the key may fall or be stolen. It is better to install using self-tapping screws. When installing outdoors, it is important to ensure there is a canopy to protect from water and sun.

There are also no problems with installing the product inside the house. If you have a large room, second floor or workshop, it is worth installing an additional sound source. In this case, you can exclude the possibility that the call was not heard.

The installation takes place in several stages:

1. Study of the configuration. At this step it is necessary to inspect the composition of the product. Advanced models may have additional devices, for example, video cameras, motion sensors and others. It is important that all items are in the box (taking into account the existing list).
2. Selecting a location for installation. When searching for an installation point, one of three options is available. A common way is to mount it on the door (directly into a metal or wooden panel). Alternatively, you can install a wireless key near the entrance (near the trim). This will require the use of screws. For private houses or cottages, installation near the gate is suitable. When searching for a location, it is important to ensure protection from moisture and dust.

3. Installation. After selecting a suitable mounting point, you can proceed directly to installation. When fastening near the door, we make holes using a hammer drill, having previously marked the place of fixation. To avoid mistakes, the drill diameter must be selected in advance. Next, install the button using self-tapping screws. If there was a wired product in the same place, it must be removed after first removing the voltage from the connected wires. If the old holes are not suitable for installing a new product, they should be covered with putty.
4. Installation of blocks indoors. Internal elements do not have to be mounted on the wall. An alternative option is to install the product on a bedside table near the door or near the place of use. To mount it to the wall you will need the hammer drill mentioned above. If the bell needs power, we supply it taking into account the recommendations in the instructions.

At the final stage, it remains to check the functionality of the device. After pressing the key, music should sound (provided that it is installed correctly). From this moment you can use the device.

Installation of the device

To avoid problems with installing a wireless call in the future, you should decide in advance on the fastening - it can be regular Velcro or screws. The second option is, of course, preferable, as it is more reliable.

If the choice is made, the next question is the installation location. Regarding this, the following options are possible:

1. Door. If you can’t screw the screw to the wall or the Velcro doesn’t stick to a certain surface, you can attach the bell directly to the door.
2. Next to the door. Often the bell is mounted next to the entrance at an accessible height.
3. Gate. This applies to street options. When installing a wireless bell on a gate, you should choose the right place so that the device receives as little precipitation and sunlight as possible.

As for the receiver and speakers with screens, they are installed in any part of the house. But there are still certain recommended places - this is the area near the front door, as well as places where the sound from the central bell weakly reaches. You can install them in a workshop, basement or residential attic.
