Multi webcam setup on one computer?

Hi, I'm wondering if there is a way to setup multiple webcams to one PC via usb?

I enjoying spying on my pet crabs but I can't always walk back and forth to go see them. I'd like to be able to setup a few cams (2 or 3) at different angles around the aquarium and be able to simply open up my webcams like a multiscreen cam view or be able to switch back n forth (like channel surfing) to see different cams or angles while working on my computer. I currently have ONE webcam setup but it's an overhead shot. It's quite convenient to be able to just view them quickly on my computer just to see what they are up to.

Is there any such software or webcam that allows for this? I don't want to invest in an actual security surveillance system with multi monitors and tvs. The quality doesn't need to be great either. I'm fine with 640x480 15-30fps.

Note: I'm aware that I could just move the aquarium beside my computer monitor but that's not what I want to do. I'm just looking for a multi-webcam setup software if such a thing exists for PC.

 

thanks, i'll give that a try.
