Mobility
The SCOPIA® VC240 system can be moved easily. To establish a connection, each
new location will need the local area network information re-entered into the
configuration menu.

Detailed Video Tests
The SCOPIA® VC240 includes analogue PC and DVI-D inputs which may only be
transmitted via the H.239 second channel at 2-3 frames per second, sharing the
available bandwidth with the main camera. For this reason the normal subjective
video quality tests could not be carried out.
Appendix 3
Detailed Audio Tests
The SCOPIA® VC240 includes only one external audio input with fixed echo
cancellation. As the echo cancellation could not be turned off the normal audio
quality tests could not be carried out.
The echo canceller is fully automatic in operation. The quality of echo cancellation
and doubletalk from the system was very good. While a participant was speaking
the integral microphone generated significant background noise, but when
participants stopped talking, the CODEC’s Noise Gating feature produced silence.
This contrast was distracting. Using an external headset microphone did reduce this
effect but background noise was still evident.
