Motion detection with IP cameras

This is semi-related to a previous issue (which I had directly contacted Bluecherry)...

Backstory: We have a PC with a MPEG4 card and several IP cameras. We have 8 Analog cameras hooked up on the MPEG4 card and 5 Megapixel IP cameras (ACTi-1231). The PC was a 2.5GHz dual core CPU with 2GB of DDR3 RAM and 1TB of storage.

We where having issues with the video "smearing" with Motion Detection enabled on the IP cameras. After talking with BC support, we decided to take the following steps:

-We upgraded the Bluecherry software to the latest version (currently 2.0.2)

-The PC has been upgraded to a 2.9GHz Quad-core CPU and 4GB of RAM

The "smearing" issue is gone on the video, but now we have random artifacts on recorded video. That is a minor issue.

Due to time constraints, we turned off all motion detection on IP cameras. Unfortunately that means consuming a massive amount of space and only being able to record a limited amount of video. After tuning MySQL, I turned the motion detection back on for 2 of the IP cameras. That ran great for almost three days, load average was never above 0.60 for 15/min interval. Motion detection worked properly and was almost artifact free.

I turned on motion detection on a 3rd camera this morning and now the load average for 15 min is above 2.50 (still shouldn't be an issue for a quad core).

Currently, two of the IP cameras show "In Progress" for the duration, but seem to be stuck at that point. The motion event on one camera started at 09:20:29 and it is currently 15:16. The other camera shows motion event at 09:03:47 (again, it's 15:16). The 3rd camera is showing motion events, but has stopped doing so at 14:40:21. I can watch the feed directly from the camera and I see motion, but Bluecherry is not doing anything about it.
