Wireless doorbells
Wireless
— in wireless models, communication between the transmitter and receiver is established by radio. The signal between the links of the device reaches a distance of 30-100 metres. The competitive advantage of calls of this type is the absence of the need to carry out installation work related to laying wires from the call panel to the receiving part of the device. Wireless bells are often powered by a battery or batteries, and are useful in places where there is no electricity or access to electrical communications is difficult.Show
