Calculating Hardware
It's been many years since I've used Zoneminder and I was thinking of getting some hardware, IP megapixel cameras and setting everything up. How can I calculate the load that will be placed on the system? If I know the size of the images being captured, shouldn't it be possible to approximately estimate the maximum throughput, RAM and CPU requirements?
Re: Calculating Hardware
Not sure if exact estimate is possible. But I just setup a small system - got a Pentium (N3700) NUC, 8GB of RAM, 2TB HDD. I have 2 Dahua cameras hooked up, capturing grayscale images @1080P @ 10fps, via FFMPEG (MJPEG quality sucks on Dahuas). The load on the system during the day is about 0.8-0.9 and during night it's about 1.0 (I think dark images require some more processing power for compression).
Considering that the NUC has 4 cores, I should be able to handle 5 cameras @1080P in total, wouldn't put more than that. If I bring it down to 720P, can probably go up to 8-10 cameras. It'll probably handle even more cameras if captured via MJPEG. Just an estimate of course. Once I hook up 2 more cameras, I'll have better idea.
The whole thing draws about 10W of electricity.
