Intercom systems allow communications between an entrance door and those inside the building. On pressing the ‘press for access’ button on the intercom panel, handset(s) can ring inside the building and a two-way conversation can take place.
Once the identity of the caller is confirmed, the door can be unlocked by pressing a button on the handset allowing the visitor entry.
These systems allow entrances to remain secure without impeding entry to visitors. They can be combined with a built in video camera to provide an image at the handset(s) to aid identification of the caller.
A keypad or proximity card reader can be incorporated into the intercom panel to allow entry without needing to use the intercom.
