Just to update my earlier comment-
We've been deploying GV-VMS v15 on new systems for about 4 months now and it is definitely much more stable than v14. Have not had any issues that I can attribute to a bug.
And just to give Geovision some credit, we do have a few v14 systems out there that started off quite 'rough' but Geovision was able to log into and patch them up and they have been rock solid for close to a year now. (they are v14 but 'patched' to run a few v15 components). If anyone is having issues, email firstname.lastname@example.org
, the support is VERY good, better than most company's I've dealt with.
