In case anyone has cameras around their house and was wanting to be able to view them on the iPronto I thought I would tell you what I have found that works really well.
My setup at home includes 5 day/night analog cameras that I can watch on any of my TV's. I bought an analog/digital converter from Stardot-tech (called Express6)
http://www.stardot-tech.com/ and it works brilliantly.
Basically the Express6 is a web server that you can view from your iPronto. It works best if you view 1 camera at a time. In my case I like to always view our nursery or the front door. It is nice to be able to view the baby right there on the remote while we watch TV or keep an eye on the front door.
Best,
Clay
