Re: [Motion-user] How many cameras?

[Roman G. <hac...@gm...>]

To put things into perspective, I use a Q6600 (4x2.4ghz) with 8x25fps
analog cameras and when all cameras have heavy motion, the CPU load is
around 80%.

On something as old as 2 x 1.2ghz P3, I can't imagine you'll be able
to support more than 2-3 cameras if you want high framerate.

Motion uses ffmpeg for video and on something like a 1.2ghz P3 I don't
think you get any more than 15fps, so with 2 maybe you'll do 30fps
total -- so with 8 cameras that's less than 4fps per camera.

Good luck though!
