if you have broadband you can buy a webcam and leave it plugged into your PC...cheapest and easiest...you may need someone to set this up for you. CSL also have a service for linking your 3G phone to your PC based webcam if you need more flexibility. Need to consider one webcam can only cover so much of one room (the one is plugged into) so if you want any more you will need multiple cameras. You could then view them by visiting a web page..
I've heard of CSL method but sounds expensive as I would need to buy 3G phone :)
Getting lots of web cams together on a broadband line sounds the best. What software do I need to make this work? Obviously I would need web cams and lots of wiring.
