Installation notes
To ensure that the panel can work properly in a VoIP video intercom system, take into account the
following factors:
- Video compression supported by the panel: H264 (configure the outdoor position so it uses this
video compression)
-
In the condominium IP network infrastructure, connect the switches in cascade form; if other
devices apart from the video intercom need to be connected to the same network (e.g. cameras
for video surveillance), make sure “smart” switches are installed to manage the QoS (Quality of
Service) and therefore ensure that priority is given to the network traffic generated by VoIP calls
- Use network switches with the following characteristics:

Transmission speed 10/100/1000 Mbit

Professional (not consumer) type switches of renowned brands, that can guarantee
product quality and reliability

Meeting the requirements of the type of installation (board or surface-mounting) and the
space occupied

Presence of PoE ports if necessary, to power the panels (in condominiums, it is
recommended that the touch panels be powered in any case with an auxiliary power supply
to prevent any video intercom system problems from cutting off the supply to the panel and
making it impossible to use domotic supervision)
-
Taking into consideration the band occupation of a video intercom call; for instance, a call with
video resolution VGA (640x480) and 15 fps, 512 kbps of band, plus approximately 80 kbps for the
audio communication
