How many cams (of the same type) can be used on Raspberry Pi?

I need to capture four streams simultaneously using Zoneminder.

Windows 7 and iSpy can not handle four cams from same mfg and device driver. Two of the same type per USB bus is all that can used, at least from what we could figure.

There are video grabbers which can forward video from 4 analogue cameras into single USB port. Grabbing is software multiplexed, so don't expect more then few frames per second.

This will depend as much on the webcam hardware, drivers, and software as much as it will on the Windows machine or Raspberry Pi.

I can't say for certain without running some tests, but I'd be surprised if the RPi (1 or 2) had the CPU power to handle more than one camera simultaneously. Under certain conditions you might be able to handle 2, but 4 just isn't going to happen.

Your project sounds like it needs some fairly specialized hardware. I doubt a single hobbyist board is going to cut it.
