Checkout a company called PHASYS (www.phasys.com) in Alberta (Canada), they have a remote video surveillance system with a TCP/IP based monitor software that supports multiple cameras and I/O ports... They have a cool demo, you can ptz cameras, switch cameras (zones), turn lights on-off, control a 'crane' (yes! a little crane with a net to trap the 'crook', etc. (Note: you have to download their client)...
