Wireless doorbells can be divided into wireless non-visual doorbells and wireless video doorbells based on the transmitted content. Wireless non-visual doorbells only transmit voice signals. When the visitor rings the doorbell, the owner can only hear the sound, but cannot see the visitor's image. The wireless video doorbell can both make a voice call and see the image of the visitor. The wireless doorbell is divided into the energy supply of the transmitter and can be divided into active wireless doorbell and passive wireless doorbell. Passive wireless doorbell means that the transmitter is driven by the visitor's conversion of the energy of the doorbell into electricity (no battery required). The active wireless doorbell is powered by an internal battery.

Different from wired building intercom, wireless doorbell is suitable for single-family, mainly used in villas, apartments, hotels and offices.
