brilliant. much appreciated, ill report back once ive had a chance to try recreating.

As title suggests. I appear to have deleted the filter option PurgeWhenFull Bit of a mistake. I would appreciate it if someone could tell me how to recover it or recreate it :S Ive just managed to set up zm 1.25 on Ubuntu basic server 12.04 LTS with a Kodicom 4400r card after a series of efforts ...

So if I understand things correctly mjpeg will put higher loads on the PC than h264 will?

not done it myself but afaik needs to be set both at server and switch, therefore requiring capable switches, passive/unmanaged afaik arent up to the job.

google nic bonding or nic teaming.

forgot to ask, is that h264 youre taking from cameras?

ok, interesting. thanks for the detailed breakdown. Cost of ddr3 now such prob just as well go 8gb anyway. ill prob be running 2 x gigabit networks on netgear prosafe unmanaged switches with a mikrotik 802.11n 5ghz bridge in the middle, most cams will be on 1 side, less cams and nvr on other side ...

nice, thanks for replying, ill prob be back to ask questions come the time I try a setup

system will initially be 3 cams with up to 8/9 maximum, do you think 4gb should do for ram or are there benefits on using 8gb combined with a 64bit server distro, benefits specific to zm i mean.

Its always dependencies with things like this in linux

Annoying, it wont let me post links, was going to link to a guide that seemed to fit for you that I found.

Google "ffmpeg all codecs x264 debian" some results in fist page of results seem to be suited to your purposes.

Thanks for responding. Hope it is, wanted to try it for some time and now an opportunity has arisen, however its a system Im doing for someone and im hesitant to set it up long term if the development has ceased. It would be a great pity, I have a lot of respect for open source developers and ...

thanks for responding, thanks.

similarly just got one initially to test. I wont be testing for a few days yet but I will report back if I can.

Could this be down to dependencies like ffmpeg libx264 etc?

Things look like theyve slowed down recently looking at announcements etc.

Is zoneminder still under active development?

How did you get on?

Glad it worked for ispy, thats one of my fallback options

Im about to build a system initially using 3 of the AVN257 cameras and I hope to use zoneminder and h.264 from the cameras. Theyre nice cameras with a decent spec for the price, I struggled to find better for less.

Thinking of building a PC for zm, possibly small ssd for boot, system etc and a pair of mirror raid drives for storage. Or does zm do much of its thing resident in memory once loaded and ssd is overkill? How/where does zm store video? could I possibly assign softraid storage to that specific mount ...

failure testing, disconnect a camera physically and see if it does what it should

Just been trying to work out things myself, these might help :

cant seem to post links, forum rules?

google h264 calculator, video bitrate calculator etc. first few results should be useful.
