I don't upgrade on a regular basis but I decided to upgrade to 5.2.9.12 to take advantage of the new substream feature - what an awesome update! I can't believe the difference it made in cpu usage. Anyway, I wanted to tweak the motion detection, object size, etc with the new substream working. I checked "Test run video through motion detector" for a little help and sometimes it causes the BI console to crash. Sometimes I can run the same alert again and it does not crash. Alerts on some cameras seem more prone to this than others. Anyone else noticing any problems like this?
