hy,
well i have big problem, i need to buy a new pc to make it a survailance kit with zoneminder, thing is i dont know what to get so i can record about 6-8 cameras at 640x480 with modect...
i tought to get a dell optiplex 755 with core2duo @ 1800ghz 4gb ram and 2x 1tb raid1 sata drives. what do u guys think? will this machine work?
ps : i also intend to have a ftp on it so i can store a few backups from a pc in lan once a week.
thanks
how many cameras ?
Hi,
It depends on the type of input (mpeg4 decoding takes processor time) framerate and the number of zones. Theoretically it shoud be enough
Now I have 4 analog cameras, BT8787 based card, until 5FPS the load is under 1. (dualcore AMD 5400+) The IO bandwidth is more important, use fast disks or striping (if you have more disks and need redundancy: RAID1+0)
The continous recording fully loads the IO capacity of my 7200RPM 320GB disk, so if I need to delete a lot of events, it takes hours.

Your pc should be enough to carry full load. To compare: 4 analog cameras 640*480*24bit at 5fps and one IP camera (Aviosys) 640*480*24bit at 5fps works well on AMD AthlonXP 1800+; RAM 768MB; HDD WD500GB 7200rpm; Ubuntu 9.04 server - average processor load 65%.
Now - a small upgrade to Celeron D 2,4GHz; RAM 1GB; HDD WD 500 7200rpm; Ubuntu 9.04 server and + one more analog camera - average processor load 40%.
