Although many people now install intercoms, the doorbell has not lost its popularity. This is due to the low cost of such a device and its availability. The usual calls were replaced by wireless models. It is so easy to mount a modern wireless bell that anyone can do it. The device has a rather small transmitter and practically does not differ in size from a wired call button. Installation of a motion sensor, video eyelet, backlight and anti-vandal protection on such devices can increase the comfort of their use.

    Modern wireless calls can be equipped with additional devices, for example, a video eyelet, a motion sensor, etc.

Principle of operation

Although the internal structure of the wireless call differs from the usual one, they have the same principle of operation. From the button, the signal is sent to the receiver, which notifies the arrival of the guest with a loud sound or melody. The only difference is that for wired models, the call is transmitted via cable, and for wireless models, via radio.

The wireless ringer device is pretty simple:

  • a button that is a signal transmitter;

Such a device allows you to install the bell and the button in convenient places, since they are powered by a rechargeable battery or batteries and do not require a network connection. Some models of wireless devices may have a combined power supply principle. In this case, the button is powered by batteries, and the main unit is powered by the mains.

Remember that the range of a wireless call in reality may be less than that indicated in its passport, since the signal is partially jammed by concrete or brick walls, metal doors and other structures

Types of wireless calls and their features

In the modern construction market, there is a fairly large range of wireless calls. To choose them correctly, you need to familiarize yourself with the existing offer and the features of different models.

First of all, such calls differ in terms of range. It is necessary to consider where you will install such a device: on the doors of an apartment or on the gate of a private house. Wireless calls can be:

  • apartment;
  • street. When installed outdoors, the range of the call must be 20-25% greater than the distance between the transmitter and receiver.

Advantages and disadvantages

Most people prefer wireless doorbell models because of their obvious advantages:

  • lack of wires - they do not need to be hidden and they will not spoil the design of the rooms;
  • non-volatility - such devices operate on batteries or accumulators and do not require a network connection;
  • simple installation - even a beginner can do it;
  • different configurations - the possibility of simultaneous operation of several buttons and speakers in the same network increases the comfort of using the call;
  • ease of dismantling - it is very easy to move the speaker or button to a more convenient place;
  • beautiful appearance - modern models differ in both color and shape of the case, so you can choose a bell for any room design.

This is not to say that a wireless call is the ideal solution. Like any other device, it also has some disadvantages, which are most often found in cheap models:

  • poor quality mount. Most often this applies to devices mounted with Velcro. After a while, such fastening may loosen, as a result of which the bell falls and is damaged;
  • the need to replace batteries or accumulators. It is necessary to periodically monitor the state of charge and change the batteries, otherwise the call will stop working;
  • leaky performance. Under the influence of moisture, the elements of the unprotected button are damaged and it fails;
  • the possibility of loss of communication. When the power of the batteries is weak or there are obstacles in the signal path, the signal may not reach the receiver.

Most of the described shortcomings are absent in high-quality models of wireless calls

What to look for when choosing

To choose the right wireless call, you need to decide on the place of its installation, and then analyze the following features:

  • type and number of batteries used;
  • button and bell body design;
  • the number of melodies and the ability to record new sounds;


    Usually, wireless calls have the ability to select a melody, and in some models you can record your own signals.

  • the range of the call, this is especially important for street models;
  • number of buttons and speakers. It is necessary to study not only the complete set of the call, but also its possible compatibility with other devices, so that later there will be no problems;
  • workmanship and body material. For outdoor models, a high level of moisture protection is very important;
  • manufacturer's reputation. It is better to buy products from well-known brands and refuse fakes;
  • availability of additional functions. If they are, decide whether you need them, otherwise you will simply overpay the money;
  • warranty period - the longer it is, the better the product is;
  • installation method. It can be either double-sided tape or self-tapping screws. The second option is much more reliable.

The difference between street and apartment models

Usually commercially available wireless doorbells for indoor or outdoor installation. Obviously, street models can be installed in an apartment, but they will cost more due to their greater functionality.

  1. A feature of apartment bells is a simpler device, since they do not require additional protection from external negative factors. The range of such models is usually from 3 to 10 meters, while street calls can work at a distance of up to 80–100 m.
  2. The bell buttons, which are installed on the gate at the entrance to the house, must be well protected from moisture, otherwise they will stop working at the first precipitation. When choosing such models, it is imperative to look at the level of their moisture protection, it must be at least IP44. For additional protection of street models, manufacturers produce protective visors. If necessary, you can make such a visor yourself. In addition, street models must tolerate both high and low temperatures, as well as its drops. To protect against vandals, their case is made more durable and reliable.

    Tools are required to install the bell on self-tapping screws, if installation is done with Velcro, then they are not needed

Installation must be carried out in the following order:

  1. Inspection of the call and checking its completeness. They check the presence of fasteners, it can be screws or Velcro.
  2. Choosing a place for installation. Determined with the installation locations of the button and speaker. It is safer to mount the button using self-tapping screws, since the Velcro weakens over time and the button may fall off. For the button, choose a place next to the door or directly on the door leaf.

Repair of a wireless call

Although high quality wireless calls are quite reliable devices, sometimes there are situations when they fail.

The main causes of breakdowns:

  • short circuit in the device circuit. It is necessary to find a short circuit, eliminate it and replace the failed parts;
  • a sharp change in ambient temperature and high humidity;
  • the batteries or accumulator are not charged enough to transmit the signal to the receiver. The batteries must be replaced.

Another common cause is the frequency of the transmitter and receiver. In this case, it is necessary to adjust it:

  • using a fiberglass screwdriver, it is necessary to tighten the adjusting screw of the inductor in the button;

    To adjust the frequency of the transmitter, tighten the screw of the inductor

  • after each turn of the screw, press the button and move away from the receiver together with the button. When the maximum sensing distance is reached, the button is replaced. You should remember the number of turns performed so that in case of failure you can return everything to its original position.

The owners of cheap Chinese devices often complain about the spontaneous ringing. This is due to the fact that their call frequency coincides with the call frequency of their neighbors. You can solve this problem like this:

  • partially shield the receiver with foil. This will help reduce its sensitivity, and it will not respond to the neighbors button;
  • improve the waterproofing of the button so that moisture does not get into it, causing a short circuit and damage to parts;
  • buy a new call with a different working frequency.
