BI Choppy Recording

[holytiger]

Setup:
40 cams (about 50/50 wired vs wireless)
30 fps

BI installed on Win 7 64, i7 3.4GHz, 8 GB memory machine and recordings stored on an attached USB 3.0 raid (standard 1TB drives).

Recordings stored as Blue Iris DVR and re-encoded with MPEG 4 settings.

Any suggestions on fixing this?

CPU stays generally in the 80s percentage wise.

I tried writing direct to disc, changing some wireless cams to wired, lowering the fps. But no difference with the test cam recordings.

Make sure to match the iframe interval and fps.
Also increase the receive buffer to 20mb in BI.
Set windows to high performance.

RAID using USB disks? Surely not.

And go back to direct to disc recording. A combination of the suggestions here should fix the issue. I had the same problem when my utilization was above 75%.
