In reply to Bellie:
I have some Foscam WiFi cameras monitored by a program called Blue Iris.
Blue Iris is excellent, Foscam cameras are best avoided, as they are OK if you manage to get good ones but most seem to be crap (2 out of 5 never a problem, the other 3 had to be replaced on numerous occasions when they just failed to work, packed up or bricked on an update).
You can get a free copy of Blue Iris limited to one camera and when you figure out all the built in options is well worth the money for the full version.
