Wireless door bells

Doorbell and video intercom system

A wireless doorbell is an electronic device for sound signaling when activated remotely by a button. When a button, usually installed outside the room, is pressed, an electrical impulse is transmitted, which triggers a doorbell.

Wireless doorbell

Doorbells and intercom systems are extremely important when building systems for buildings and industrial premises. A wireless doorbell, unlike standard alarm systems, uses a radio signal and does not require unnecessary cables for connection.

Wireless doorbell device

• button (transmitter);
• receiver (doorbell);
• power supply (battery);

Wireless doorbell systems are electrical systems consisting of a transmitter (button) and a receiver that use a radio frequency signal (RF) or Wi-Fi to transmit a signal. Some systems have, in addition to a doorbell system, a video system with a connected video camera.

Transmitter

The button is a device that sends the signal by pressing. It is a small battery-powered device that is mounted on the front door or at an access control location.

Receiver

The receiver is an electrical device, doorbell or video camera, that receives the remote signal from the button and can emit sound or transmit an image. Unlike the button, the wireless doorbell can be powered by a battery or by an adapter powered by the 230 VAC network.

Advantages of wireless doorbells

Wireless doorbells perform the same functions as wired ones, but have several major advantages over them:

• Easy and quick installation. The principle of operation of wireless doorbells implies the complete absence of wiring, which reduces the installation only to installing the two modules in appropriate places, inserting batteries and turning them on.
• Aesthetics and style. The lack of cables means that nothing will disturb the appearance of the interior and exterior of the room or building in which the wireless doorbell is installed. In addition, some of the wireless doorbells have a sophisticated and stylish design, adding additional aesthetics to the home or office.
• Easy maintenance and long-lasting use. The lack of wiring also means that there is no risk of a cable breaking somewhere along the route and its difficult discovery for repair. The only maintenance that a wireless doorbell requires is periodic battery replacement.
