In the past, the main surveillance systems seemed to be CCTV, that broadcast its signal in analog format. The signals did not reach that far, and the pictures would have to be recorded, and then watched at a later date on a video recorder. This was not only a pain, but pictures were not in real time. This system was fine as long as you were in the house, however, how about when you are away?
Thanks to the internet, which has bought many new and exciting technologies into the home, web cams are now able to record movements in your home and send them, via the internet, for you to watch, in real time.
