Nice setup K33.
I run a program called iCam (I think it was $2.99) on my iPhone. It connects to a server in my house (macMini, running 10.6 desktop, and iCam's free server software) that is connected to a USB cam. Program supports both USB based, and IP based cams. Once it's set up, no images ever touch a 3rd party server, only the initial handshake. iCam supports 4 cameras, and they make a pro version that supports 16. I can even have it record motion events, and email them to me. Viewer is available on the iPhone/iPad, and in a web browser. It's password encrypted, so (kinda) secure.
Does that Hanna unit have the ability to output (like over a serial cable) the meter readings? I'd love to have something setup that would notify me when levels were out of range. Being able to check into things is nice, but being notified of the problem, before it gets out of hand, is awesome. I have the PC end sorted out, and have a few program ideas, but nothing in hand yet. Dreaming of the fully-automated setup.
