How wireless door intercom systems work?
A typical two-way wireless door intercom system is made up of a door station unit and a master unit. The door station unit contains a doorbell button, a microphone and a speaker. The door station unit can be mounted on the outside of the door to the main entrance of your house or the entrance of a building. The master unit is kept in the house, conveniently placed for your use. It has a ‘talk’ button, a microphone and a speaker. Both these units can communicate with each other by sending radio signals. When the visitor presses the doorbell button, the door station unit transmits a signal to the master unit which alerts you of a visitor’s presence. Pressing the doorbell button also activates the microphone and speaker in the door station unit. By pressing the ‘talk’ button on the master unit, you can converse with the visitor. This system can also be installed and used in a business establishment to manage visitors. Types of wireless door intercoms A wireless door intercom is easy to in
