Has anyone worked on a BC 16 port video/audio card? It uses hardware compression and will reduce my load problems. I run a Web server /Samba server/ ZM and Power loggers. Any thoughts?
Kind Regards

OK I have my Bluecherry BC-H16480A - 16 port video, 16 port audio H.264 / I will let you know how it goes.

I tested Zoneminder several years ago with a 4 port separate bt878 chip per port card at maximum frames 20-30 frames/second
on a dedicated dual pentium 3 server board with was loaded with only the O/S and Zoneminder. The loads where always over 1.0 and at times 2.5 to 3.5
top indicated that zoneminder was only some of the problem the other I/O to the hard-drives. I also tested with ffmpeg straight from the card to hard-drive
with loads above 1.5 at these frame rates so would be interested in the results of the above card that should lower the load as long is does not have I/O issues
with the total load.
If I remember correctly a 640 x 320 24bit frame was about 800k from an analogue camera so it had the cpu's busy with the pci bus overloaded, at these frame rates.

As above issues are usually disk io based. I have got around this in the past with raid 0 arrays

I agree on raid array or sas but it is not going to be cheap.
