Its is not so simple to have a program to show cams or cameras on the Ipod/Iphone touch. Search itunes app for "Cam Viewer" and check out the details that this program needs to be able to view IP cameras and cams. I had the Smartlinc from smarthome and the only cameras it supported was only a few Panasonic cameras.
Note: You better get a camera that sends SSL secure email because most ISPs require secure socket email nowdays.
