Abstract
The present disclosure discloses a multi-point reception and flexibly deployable doorbell control system. The present disclosure provides a solution for extending a wired doorbell to a wireless doorbell by connecting the voltage sensing line of a wireless transmitting device to the output terminal of the outdoor machine button of the existing wired doorbell system, detecting the voltage signal of the wired doorbell, and transmitting the signal wirelessly to a receiving device. This technical solution features two power supply modes, i.e., AC power and built-in battery, ensuring reliable system operation. The receiver can be plugged into any indoor socket, a plurality of receivers can work simultaneously, and achieves wireless extension without altering the original doorbell system.
