i think your requirements does not fit with low cost equipment. i  
don't know about a [web]cam that has good zoom and is able to record  
30f and is cheap. there will be two ways: 1) buy an (external)  
capture card and a monitoring cam (high latency). 2) buy a cheap  
camcorder (300-400eur) and plug it in to mac mini's firewire port.

should be enough,
but maybe a cheap pc + onboard/internal capture card + monitoring cam  
- commercial os would be cheaper.
