I realize this is an older post, however I have several customers still using SC 5.1 with one server and one client. I have been fighting with these genetec servers for a long time now. I have several, separate locations with lagging issues. Constant buffering video, running slow. One thing I was told by genetec was to turn video caching off, hasn't fixed anything. One of my system runs 95 axis cameras, again one server, one client. I am beginning to wondering if we are setting them up correctly. The instructions come from the client/genetec/IT dept. I don't understand why a client pulls up video to review and it buffers for 30secs before you can review video. Where is the bottleneck? Client machine or server?
This post helped me alot as for getting some kind of insight into how this software functions. With the cost of this software and the robust(ness) of the software, I don't think i should have any issues with lagging video
