Hey guys, thanks a lot for this thread. I have 10 câmeras in my store (runing at 720p @ 10 fps), using motion detection to record all of then. I have tried Zoneminder for 3 months in a Ubuntu VM, after several troubles (change record files folder, 100gb/day with tons of files, socks limits on browser), a LOT of CPU processing (more than 50% when viewing all cameras), several crashs (that made me set to mocord just 4 of 10 cameras) and a lot of headache, I finally decided to check for alternatives. I have tried Shinobi too, maybe its better than Zoneminder, but still a lot of trouble for just a few cameras. When I was thinking to stick with Shinobi, moeiscool decided to change the project to have a "pro" version, maybe with a more mature software it will be a good option. And then I found BI, now it's running in a Virtualbox VM for 4 days. Files: 30gb up to now CPU Load - i7 920: 15% (idle) and 20~25% with 5~6 cameras detecting movements and recording. Viewing all cameras through GUI at 8 fps over a RDP connection (cameras in Brazil while I'm in USA/Germany). My tests will continue for more a couple of days and I will probably order the full version of Blue Iris.
