I have done MJPEG 1600x1200@8fps on AMD X2 4400+, 2 GB RAM. I could only do one camera though, so I settled with 800x600 with 2 cameras. It's doable but the server has to be really really fast CPU-wise and you have to dedicate separate network just for the CCTV. see this thread http://www.zoneminder...

works great, thanks I don't know why though

Is it possible to use the filter to delete all events older than a month? It could fire up every week or something like that. I can only see the purgewhenfull script everywhere.

Thanks

kingofkya: Thanks for the Frame Skip tip! The MMX libjpeg is 32bit only as I said above.

mitch: yeah, I guess it would, I plan to fiddle around it when I have some time.

I think the main problem is the way Zoneminder saves events. It saves them as series of small jpegs instead of employing something like one mjpeg for one event. ZoneMinder has to decode jpeg, analyse it, encode it again and save it. The filesystem would definitely work better if it had to read/write...

timcraig: done and done. I was already using the fast method of motion detection so it didn't really help though :-( OK, so the load is down from 1.2 to 0.9-1.0 for just one camera@4fps,15fps when in alarm state. This still sucks :) I would ideally want 8fps@idle and 15fps alarm state for both camer...

whatboy: 32bit only, I am on amd64
mitch: will try that when I get home, won't it just postpone the bottleneck until 2 alarms kick off at once?

Hi, I bought 2 vivotek fd7160 cameras. So far they are great, mjpeg is clean, with all the headers and bits and they are performing nicely. They are capable of 1600x1200 mjpeg stream at 15fps. However my dual core AMD 4400+ server with 2GB RAM can't keep up. I thought this wouldn't be a problem, but...
