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.
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 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.
