Quick answer
A wireless intercom sends audio or video between the door or gate and the inside without a dedicated intercom cable. Wi-Fi models join your router and ring your phone; radio models talk directly between units; GSM models call your mobile over the cellular network. The door unit still needs power, and walls and distance limit range.
