• ISDN access: NetCam communicates with corresponding receiver units via ISDN
(Integrated Services Digital Network), the digital telephone network. The basic
rate ISDN access S
0
offers two channels with a capacity of 64kbit/s each. Due to
synchronization of information, NetCam is able to utilize both channels at the
same time, while already functioning with one channel only. NetCam can also be
operated over a PBX unit, as long as the PBX system internally supplies S
0
-ac-
cess ports.
• Modem support: In addition to ISDN NetCam may also communicate over con-
ventional analog telephone lines using an external modem. The modem is to be
connected at the NetCam ’Modem’ port. The required cable is available as acces-
sory from the manufacturer.
• GSM support: NetCam is also able to communicate via wireless networks such
as GSM. Connection is facilitated using a suitable GSM modem, e.g. the Siemens
M1 module.
• Video source: For most applications a camera with a BAS or FBAS output is used
as a video source. NetCam supports PAL as well as NTSC standard video sourc-
es (not required for NetCamPlus).
