In any house, doorbells are used to notify the owners of the arrival of guests. There are wired and wireless models that have similar functionality and reliability, but differ in the way of installation and the complexity of installation. A wired call to the door to an apartment is more common, as there are rarely power outages in apartment buildings. In private houses, it is more convenient to use a wireless call, the features of which must be taken into account when buying.
What is a wireless doorbell
A wireless doorbell consists of several important components that fulfill their role. These include:
- Speaker. A sound appears from it when guests press the bell.
- Button. The mechanism on which you need to press so that the contacts are closed and a sound appears.
- Transmitter. Transmits a signal over the radio channel from the button to the speaker.
Main applications of the wireless doorbell:
- Private houses. Often they are installed on a wicket, which is located at a distance from the house.
- Summer cottages, where the entrance is also remote from the building.
- Apartments.
- Warehouses, offices.

Operating principle
The underwater and wireless devices work in a similar way. For wired models, pressing the button closes the circuit and sends the signal to the speaker over the wire. For wireless products, there is no need to close the circuit. When you press the button, the transmitter is triggered, which sends a signal wirelessly to the call. There are devices with a combined operating principle. For example, a button can be powered by a battery, and the sound source itself can be powered from a stationary outlet.
The signal transmission speed depends on various factors. These include the distance over which the wireless signal should be transmitted, the presence of obstacles. It is important to remember that concrete and metal structures, as well as other massive obstructions, can reduce signal strength.
The product diagram is simple. The device has two boards for a button and a receiver. There is also a third circuit for the signal generator, which is fault-free.
Types of devices
The modern wireless remote bell can be classified according to various criteria. The type of food is distinguished:
- Separate food. The button is powered by the battery, and the call is from the home network.
- General food. Both cells are powered by a battery.
By functional purpose:
- Street. Protected from moisture, ultraviolet radiation and other negative environmental factors.
- For home use.
According to the configuration, they are divided by the number of buttons and speakers. There are jobs 1 + 1, 2 + 1, 1 + 2 or 2 + 2, respectively.
There is also a division into functional parts. The device can be supplemented with Wi-Fi, camera, microphone and other components.
Specifications
When buying a device, be sure to pay attention to the main technical parameters. The basic characteristics include:

When choosing the best circuit, you need to take into account that additional parts, especially those working around the clock, need a more stable power supply. Options are possible, for example, activating the camera by pressing a button, schemes with a motion sensor. Additional options add to the cost of the entire system.
The difference between home and outdoor devices
Before buying a wireless bell, you need to decide in advance where it will be installed. There are two basic options - external and internal installation. In the case of installation in the house, it is enough to buy an inexpensive, simple model with Velcro fixation. Such devices do not require anti-vandal protection or moisture resistance. If the device will work on the street, you need to take the selection seriously. You should pay attention to the following indicators:
- Temperature Range. The call will work in winter and summer, so it must withstand positive and negative temperatures.
- The presence of a waterproof case.External influences of the environment can cause serious damage to the device, therefore it must be reliably protected.
- UV protection. Ultraviolet light can also harm the operation of the call, so you should choose products in a reliable protective case.
- Fastening. The bell must be securely fixed on the surface so that it does not fall off. Anti-vandal protection is required.
Outdoor products have more requirements for safety and operation, so their cost will be higher.
