In any house, calls to the front door are used, which notify the owners about the arrival of guests. There are wired and wireless models that have similar functionality and reliability, but differ in installation method and installation complexity. A wired call to the door to the apartment is more common, as in apartment buildings there is rarely a power outage. In private homes, it is more convenient to use a wireless call, the features of which must be considered when buying.
What is a doorbell wireless bell
A wireless doorbell consists of several important components that fulfill their role. These include:
- Speaker A sound appears from it when the guests press the bell.
- Button. The mechanism on which you need to click so that the contacts close and a sound appears.
- Transmitter. Transmits a signal over the air from the button to the speaker.
The main applications of the doorbell for wireless:
- Private houses. Often installed on the gate, which is located at a distance from the house.
- Cottages where the entrance is also remote from the building.
- Apartments
- Warehouses, offices.
A wireless call is an excellent replacement for a wired analogue. It can be used in any places where it is required to notify the owner of the arrival of visitors.
Advantages and disadvantages
Like any product, a wireless call has its positive and negative features. You need to familiarize yourself with these qualities before buying a device.

The best option is to use a wireless button in conjunction with the camera and other security gadgets.
Operating principle
The underwater and wireless devices work similarly. In the case of wired models, when the button is pressed, the circuit closes, and the signal is transmitted to the speaker through the wire. For wireless products, there is no need to short circuit. When a button is pressed, a transmitter is triggered, which sends a signal wirelessly to a call. There are devices with a combined principle of action. For example, a button can receive power from a battery, and the sound source itself from a stationary outlet.
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 obstacles, can reduce signal strength.
Product outline is simple. The device has two boards for the button and receiver.There is also a third circuit for a signal generator, which is characterized by the absence of failures.
Types of appliances
A modern remote wireless call can be classified according to different criteria. According to the type of food, they distinguish:
- Separate food. The button is powered by the battery, and the call is from the home network.
- General nutrition. Both cells are battery powered.
By functional purpose:
- Street Protected against moisture, ultraviolet radiation and other negative environmental factors.
- For home use.
By configuration are divided by the number of buttons and speakers. There are works 1 + 1, 2 + 1, 1 + 2 or 2 + 2, respectively.
There is a division into functional parts. The device can be supplemented with Wi-Fi, a camera, a microphone and other components.
Specifications
When buying a device, you must pay attention to the main technical parameters. The basic characteristics include:
- frequency at which the device operates;
- radius of action;
- signal type;
- number of buttons and receivers;
- power;
- way of nutrition;
- presence or highlight highlight;
- the ability to set a ringtone;
- sound adjustment;
- the possibility of use for intercoms or video eyes;
- sending SMS messages to the owner;
- night light, motion sensor;
- working temperatures;
- protection against aggressive influences.
A standard electronic call works in the frequency range from 433 to 434 MHz, but there are products at 315 MHz. When choosing a device in range, you need to consider the ability to bypass obstacles. Concrete walls and armored doors reduce the range, while drywall and wood transmit electromagnetic waves well.
Accessories for expanding functionality
To create a reliable security system, you should add other protective equipment to the call. You can immediately buy a kit or build the entire system yourself from scratch.
Additional details include:
- Video-eye. This is a device that works on an ongoing basis or after a motion sensor responds. The picture is transferred to a monitor or to a computer.
- Motion Sensor. The device reacts when someone appears near the door. He can notify the owners of the arrival of guests even before they click on the button. It can also start the video eye or video recording.
- Intercom. The assembled system is more complex and consists of cameras, a monitor, speakers, a microphone. Some devices can send SMS to the owner, have backlight and volume control.
- Additional cameras. They allow the owner of the apartment to track who came to visit and make a decision about opening the door. The quality of image transmission on the screen and the viewing angle directly depends on the camcorder itself.
When choosing the best scheme, you need to consider that additional parts, especially those working around the clock, need a more stable power supply. There are options, for example, activation of the camera at the touch of a button, a circuit with a motion sensor. Additional options add to the cost of the entire system.
The difference between home devices and outdoor
Before buying a wireless call, 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. 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. The following indicators should be noted:
- Temperature Range. The call will work in winter and summer, therefore it must withstand positive and negative temperatures.
- The presence of a moisture-proof housing.External environmental influences can cause serious damage to the device, therefore it must be reliably protected.
- UV protection. Ultraviolet light can also damage the operation of the ringer, so you should choose products in a reliable protective case.
- Mount. The bell must be firmly fixed on the surface so that it does not fall off. Anti-vandal protection will be required.
Outdoor products have more requirements for safety and operation, so their cost will be higher.
Features of choice
In addition to the technical characteristics of the device, other parameters must be taken into account.
- Appearance. A wireless street bell should fit the interior.
- The number of batteries. Complex systems may require more power supplies.
- Protective housing. Considered for street models.
- Melody. In some types of wireless calls, you can put your own tunes.
