You will need to install the microphone, VGA feed, and cameras common to any other Matterhorn CA, then provide the MCD with power and a network connection. > 2. what is the configuration needed? Epiphan's documentation should cover that, but the configuration UI is at $DEVICE/admin (eg: http://exampleca.example.org/admin). > 3. how can connect (MCD) with core server? This is configured in the configuration UI mentioned in point 2 > 4. how can start and stop capturing (which machine is responsible to > start and stop capturing)? The ECD only supports (last I checked, this may have changed) scheduled captures, which means that the core has a set of start and stop times, and the CA just captures between pairs. Other CAs have other optional ways to capture (in-class buttons, etc), but *all* CAs have scheduled capture options.
