A bellfree video door entry system consists of a door panel, positioned at the entrance of a building, apartment stations and other telephones, placed inside of the building for the convenience of the occupants and a power supply and controller which are usually located inside an electrical cupboard. The door panel comprises of a two-way speech unit, a camera, an LED display and sixteen push buttons – which are used by a visitor to initiate a call. The apartment station, which rings in response, allows a two-way hands free conversation (a touch is required to initiate the conversation and end the conversation) whilst the caller can be observed through the integral display. The operator can selectively allow visitors access to the building by touching a pad on the apartment station and so electrically releasing the door. The bellfree digital video door entry system is suitable for any building or entry point addressing a quantity of flats where a standard panel would be larger or more expensive; this is typically from 16 flats upwards. The bellfree digital system is supplied with a dedicated door controller, for each entrance, and a video controller for every four apartment stations. The basic system supports 1 apartment station per address, and up to 3 extension apartment stations (more with additional power supplies). Multiple entrances can be supported with the addition of one panel and one door controller for each entrance.
