As someone who doesn't work for iCam but uses their services I would say iCam is one of the best options you could ever use for home security.
At this very moment I am sitting in my office and I am watching 2 cameras at my house. The webcam in my house covers my living room where I can see my dogs doing their thing while I'm not there. I have an Airlink 747W camera outside which covers my patio and back garden. I LOVE iCam, LOVE LOVE LOVE LOVE LOVE
My dog had taken serioulsy ill one day while I was at work, I caught it on my phone and rushed home to take care of him.
I have 2 webcams in my office and again the Airlink 747W pointing outside into the parking lot. From home, I've caught colleagues coming into my office who should not be there, given them a call on their cellphone and scared the beejezus outta them, love that.
The motion detection means I do not have to watch it like a hawk 24/7.
For me, iCam and the iPhone are fabulous. If you get the system I do not think you will be disappointed.
