I want to install two wireless surveillance cameras to monitor the front and back door and a wired one for iChat/additional monitoring purposes. I would like to be able to check in anytime remotely via iPhone. I am looking at a combo of these cameras:

iChat: Logitech QuickCam Vision Pro
Doors: Airlink101 SkyIPCam500W

and the iCam app on the iPhone. How does this sound? Any suggestions or experiences with similar setups to share?
