wireless cctv advice sought

[broken link removed]

I am looking for a wireless CCTV system and would appreciate any advice. I want a reasonable one to send the images to PC/TV or IP. But I read installing an IP camera needs a lot of network skills like port forwarding etc. i would hope to install it myself, something like the one in the link above

What if someone is caught on camera breaking in but then steals or breaks your PC or harddrive? I'd imagine there must be services to automatically upload the footage somewhere, maybe you can configure it only to record when an intruder is detected and so reduce the amount of data collected?
