difference between unicrypt & deltacrypt unicams

[ricou]

hi members of community
is there any one knowing the difference between the "unicam unicrypt" and the other blue one: the "unicam deltacrypt"?
is it hardware? Software? context of usage? possibilities of usage?
Both seem to work with the sparta software, so i dont understand
