panel. This door phone can satisfy your need of communication with visitors at the

means "Voice over Internet Protocol" - the door phone is connected to the computer
network and enables both P2P (peer to peer) connection - i.e. it calls to an IP address
of other VoIP device directly or it is registered to a SIP server, then it calls a phone

The basic module of the door phone always contains 2 pushbuttons and optionally the

panels enable the sets of door phone with 1 to 10 pushbuttons just by using the basic
electronics module of Fermax IP DP. You can also expand the whole system by the 8
pushbutton expansion module Fermax PBX EXP up to the limit of 64 pushbuttons. The
basic module can contain a colour camera, optionally there can be an add-on speaker
module with an amplifier Fermax PBX EA, which is used for very noisy areas. The
