For now, I don't think the multimedia stuff and home automation that is included in LinuxMCE. That said I am still interested and might try it out later. Thanks for bringing up Zoneminder hari. Seems more like the project I was looking for at this stage.
Hopefully it is matured enough to be useable.
Or Kmotion... its worth looking at that too. Kmotion is probably slightly easier to configure/setup. But Zoneminder is more feature rich overall. We integrate Kmotion into Dianemo (which is a commercial 'sister' to LinuxMCE that shares a common lineage).
All the best
