Wireless call, what is it, device, principle of operation, how to choose for a house, cottage, apartment

A wireless bell is a device used to announce the arrival of a guest, characterized by ease of installation and the absence of additional wires. The product is useful for a private house, can be used on the doors to an apartment or in the country.

In terms of functionality and reliability, the wireless bell is not inferior to the wired version, but its installation takes less time and does not require complex work. Such devices are compact, have a modern appearance and are distinguished by a wide range of models.

What are the features of wireless calls? How do they work? What types of devices are there, and what to consider when choosing? Let’s discuss these and other points in detail.

What is it, scope

Wireless bell is a device consisting of a group of elements:

1. DYNAMIC. It emits a sound when the contacts are closed.
2. BUTTON. This is a mechanical element that ensures the operation of the product.
3. TRANSMITTER. With the help of this element, the signal is transmitted from the button (located outside) to the speaker (mounted inside the room and makes a sound).

Wireless calls are used in the following cases:

1. For a private house (for example, when the gate is located at a distance from a residential building).
2. For giving, where the entrance to the site is remote from the building on the site.
3. On the door to the apartment. The option with a wireless bell is convenient for ease of installation, the ability to get away from drilling holes and laying wires.
4. Warehouses and offices. Giving a sound signal allows you to inform employees about the arrival of the client.

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

Advantages and disadvantages

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

Advantages:

1. No wires. During the installation process, you can do without a drill (except for the case of fastening the button with self-tapping screws), pulling wires or cables connecting the button and speaker. This is convenient when the product is bought for a summer residence or a private house. When installed on the door to the apartment, you can avoid peeling off the 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. Ease and high speed of installation. Fixing the product takes a few minutes. This is due to the lack of wires and complex fasteners.
3. Convenience. The use of such a product does not cause difficulties, both for guests and for the owners of the house (dacha, apartment).
4. Ease of transfer to another place. Due to the absence of wires, a wireless call can be outweighed at any time.
5. Can be used in combination with complex devices. Wireless calls can be used for an 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 suits the shape, color or material of manufacture. You can be sure that a wireless call will only decorate the interior or exterior.
7. Independent food. Ordinary bells work without batteries and you have to pull wires to supply voltage. In the case of a wireless device, this is not necessary. The voltage is supplied by batteries, so even when the light is turned off, guests will be able to notify the arrival. This feature is useful for private houses or for summer cottages where there is no electricity. An alternative option is to use a wireless bell without batteries, when powered by special batteries (sold separately).
8. Possibility of retrofitting. 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.

Disadvantages:

1. Installation of a wireless button is not possible in all cases. The installation process does not use wires, 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 mount a classic wired bell or eliminate the cause of the interference (if possible).
2. The need to change the battery. An autonomous power supply tends to be discharged, so from time to time it needs to be replaced. If you miss this point, the wireless call will not work.
3. Bad fastening. Some models are fixed with a sticky base. This option is suitable for the door to the apartment. When mounted in a country house or used for a private house, the button is fixed on the street. Under the influence of cold, it often disappears. In addition, Velcro fasteners do not withstand even light physical impact.
4. Eating probability. The presence of negative influences (for example, the ingress of moisture into the product, the influence of low temperatures or the displacement of the contact group) leads to the button freezing in the actuated position. As a result, the call works until the battery is discharged or the defect is eliminated.
5. Ease of theft. The wireless model of the call is easier to steal, because no wires are connected to it. To prevent theft, you can install a video camera at the entrance. It will be doubly helpful. Firstly, it allows you to personally look at the guest, and secondly, it will reduce the likelihood of theft.
6. No signal transmission. The presence of problems in the operation of the circuit can lead to difficulties in sending a signal from the button to the bell. Another situation is also possible, when the command comes, but there is no sound.

A wireless call is not an ideal device, but its advantages more than cover the disadvantages in its operation.

Principle of operation, scheme

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

In the wireless bell situation, the same principle is used, but there is no need to close the electrical circuit.

The principle of operation 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 triggered, sending the signal wirelessly to the receiver (call).
3. The electrical circuit is activated.
4. Power is supplied to the speakers, and music (the one programmed in the device) plays.

On sale there are models with a combined principle of operation. 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 depends 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 scheme of wireless calls is simple, which guarantees their reliability, unpretentiousness in 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, which is distinguished by the absence of failures.

Types of devices

There are two types of wireless calls:

1. With separate meals. The button is battery operated, and the bell is mains powered.
2. With shared food. In this case, both nodes are powered by a DC source (batteries).

Modern models are conditionally divided:

1. By functionality. Products can be designed for home or summer cottages (street and waterproof version), for the door to the apartment or for intercom.
2. By configuration. At the disposal of buyers there are several configuration options for 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 ​​uXNUMXbuXNUMXbthe house.
3. According to the functional “stuffing”. 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 mounted in a room with a large area. The device can be used with Smart Home systems (the site has a separate section on this topic).

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

Specifications – the main differences

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

1. The frequency of the device and the range.
2. Type of transmitted signal.
3. Number of speakers and buttons included.
4. Power and type of electrical power (mains or batteries).
5. Illumination (provided or not provided).
6. The ability to install different melodies or set your own music (using a flash drive).
7. Volume control option.
8. Support application function for intercom or video peephole.
9. Option to send an SMS message.
10. Night light function and motion sensor.
11. Operating temperature range (important when installing the button outdoors).
12. The presence of moisture protection (provided for street options).
13. Other characteristics.

As a rule, modern models of wireless calls 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. For example, a concrete wall or an armored door interferes with the signal. Drywall or wood transmits electromagnetic waves better.

Additional accessories to expand the functionality

To increase comfort and convenience, you can supplement the wireless call with additional devices. Sometimes they are included in a set of 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 joining.

Additional items include:

1. VIDEOGLASOK. It functions permanently or is activated by a motion sensor (when a person approaches the door). There are cameras associated with the bell button that only work when it is pressed. The picture received from the video eye is transmitted to a special monitor. Signal output to phone, PC or laptop is possible.
2. MOTION SENSOR. The presence of such a node allows you to inform the owner about the arrival of the guest before pressing the button. In addition, the triggering of the sensor gives a command for the operation of the video eye or starts recording (depending on the setting).
3. DOORPHONE. 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 a backlight, a volume control knob or a mute button.

In a number of devices, sending a signal about the arrival of a guest via SMS is available. It is important to note that the price of the selected model depends on the number of additional functions.

Video peephole for wireless call

With the help of an additional camera, the owner of an apartment, house or cottage can see the visitor at a distance. As a result, it is easier for him to make the decision to open 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 picture from the camera can be transmitted to a separate display, PC or laptop (depending on the selected model). The image transmission quality depends on the camera installed in the video eye.

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

1. Search for a suitable low consumption kit (if permanent video capture is required).
2. Scheme with activation of the video eye only when a button is pressed. Under such circumstances, the camera captures only the face of the caller.
3. The video eye is powered separately. In such cases, the use of a wireless call is not entirely clear, but a similar scheme is common.
4. A scheme with a motion sensor that determines the fact that a guest is near the call button. This option is convenient for controlling inadequate citizens who can play a trick on the owner. The convenience is that the video camera shoots 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 resolution of the camera. The higher this setting, the better the image.

On the other hand, with a higher resolution, the amount of video received increases greatly. In addition, higher 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 the location of its future location. There are two basic options here – indoors (for an apartment) or outdoors (for a house or for a summer residence).

In the first case, it is enough to buy a simple model, without moisture protection and a wide temperature range. If the wireless call is planned to be installed on the street, the approach to choosing 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, an outdoor wireless bell must withstand temperature fluctuations and operate over 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 mounting on the doors, it is worthwhile to provide a small visor that protects 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 to protect the wireless call from vandals, it is recommended to take models made of durable metal. The downside is that they will be more expensive.

Features of choice

When buying a wireless call, it is important to know the selection rules and be guided by them when choosing a device. It is important to pay attention to the following details:

1. A TYPE. The principle of operation of wireless calls is almost the same. The differences relate only to design, functionality and configuration.
2. APPEARANCE. When choosing, it is important to focus on the design of a 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 is trying to highlight their models and make them better than their competitors.
3. NUMBER OF BATTERIES. Depending on the complexity and layout 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 ACTIONS. When buying a wireless call for an apartment, this factor does not matter. Another thing is when the installation is planned in a private house or in the country, and the distance between the gate and the house is up to ten or more meters. When studying the range, it is important to take into account interference in the signal path. The manufacturer indicates a “clean” range, without obstacles in the form of walls or doors. That is why it is better to focus on a larger range (take with a margin).
5. CASING. For outdoor installation, you should pay attention to the material and build quality of the case. 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 take wireless calls with music replacement option. In some devices, you can insert a USB 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 a distance of interest.
8. EQUIPMENT. An equally important selection criterion is the composition of the kit. The advanced version can add a video peephole, an additional button or speakers, a motion sensor or other devices. When purchasing elements separately, it is important to clarify the possibility of their joint use.
9. MOUNTING METHOD. This is a key point that has received little attention. As a rule, fixation is provided with a simple Velcro. Under the influence of cold or other negative natural factors, it stops holding the button and peels off. The best solution is to secure the wireless bell button with self-tapping screws, but this must be possible.
10. COST. The task of the seller is to earn as much as possible on the client, so when choosing, you should not 100% follow the advice of the seller. It is important to focus on personal needs and take equipment based on your goals. It is not worth overpaying for additional features that will never be useful, or for a brand.
11. GUARANTEE PERIOD. When choosing a simple model, the probability of breakage is minimal (this is due to the absence of complex elements). Another thing is when many additional devices are included in the package. In such circumstances, you should give preference to products with a guarantee of 10 years or more.

The application of the mentioned recommendations will allow you to choose a high-quality wireless call with the necessary functionality and at an affordable price.

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

2. Proline HT-W4U01 – no less popular wireless call, working 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 allows you to get rid of the need for batteries and save money on their purchase. Moreover, wireless devices without batteries are more reliable. They are unpretentious to different weather conditions and are not afraid of oxidation of contacts.

Mounting Features

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

When choosing an option, it is important to consider that Velcro is easier to attach, but then the key may fall or be stolen. It is better to install with self-tapping screws. When installing outdoors, it is important to take care of the presence of a visor to protect against water and the sun.

There are also no problems with the installation of the product inside the house. If there is a large room, second floor or workshop, it is worth putting an additional sound source. In this case, you can exclude the option when the call was not heard.

Installation takes place in several stages:

1. Studying the set. At this step, you need to examine the composition of the product. In advanced models, there may be 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. Choice of mounting location. When searching for a point to install, one of three options is available. A common way is to mount on the door (directly into a metal or wooden sheet). Alternatively, you can install a wireless key next to the entrance (near the architraves). This will require the use of screws. For private houses or cottages, installation near the gate is suitable. When looking for a place, it is important to provide protection from moisture and dust.
3. Installation. After choosing a suitable mounting point, you can proceed directly to the installation. When fastening near the door, we make holes with a puncher, having previously outlined the place of fixation. To avoid errors, the drill diameter must be selected in advance. Next, we put the button with the help of self-tapping screws. If there was a wired product in the same place, it must be removed, after removing the voltage from the wires. If the old holes are not suitable for installing a new product, it is worth covering them 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 to the wall, you will need the puncher mentioned above. If the bell needs power, let it down, taking into account the recommendations in the instructions.

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

Results

A wireless bell is a convenient solution when you don’t want to spend time drilling holes in walls and laying wires.

Due to their functionality, ease of use and ease of installation, such products are perfect for an apartment, cottage, private house, office or other places where you need to inform about the arrival of guests.
