2. GENERAL DESCRIPTION
The N-SP80VS1 and the N-SP80AS1 are door stations for use in the SIP (Session Initiation Protocol) Intercom
system.
The door station is available in 2 models: the one with camera and the one without camera.
The station can be used not only in SIP server mode but also in peer-to-peer mode: the former enables the
station to work by connecting to the SIP server and the latter enables it to work without using the SIP server.
In this manual, the N-SP80VS1 and the N-SP80AS1 are collectively described as the door station.
