I bought myself one of these
Wireless Spy Camera (complete kit) - Spy Cam | Nanny cams | Best prices and best customer service
They also sell a set of 4 camera for $279
HS203USBx4 Mini Wireless Color Spy Cameras w/ PC USB Adapter (Set of 4)-MG
Hooked up and now i have a ghetto security monitor system that will record when it detect movement. The camera ifself doesn't come with any software. Basically it plug into your tv s-video input and you just monitor there. But since i can't be there 24/7 I went out and get myself this
Hauppauge WinTV HVR-1600 PCI TV Tuner Hardware MPEG NTSC ATSC QAM Retail Box W/ Remote & IR Receiver - HAUPPAUGE - 1181. then download ispy from
iSpy: Free Camera Security Software (Open Source). Work pretty good
I also have a dlink dcs-930L hooked up so i can monitor it on my smartphone when i'm not home.
