HI I was hoping there has been some resolution on this. I too have been having the same problem since upgrading to 2.7 this started as minor hands with the intercom system (all the touchscreens were stuck on initializing intercom, but the system worked otherwise), and has now become general system outages like you are describing. only way to fix it is to reboot, and EVERYTHING hangs until the system is reset. There is no rhyme or reason to the outages, and when I go through detective suite and look at the various things that are available, nothing is showing as an error. any thoughts? hc800 primary 2 hc300 7 touchscreens infinity edge doorstation thanks Steve
