I'm a 52 year old woman, about as technologically savvy as a goldfish.
I went over to Frys today and bought the 930L because it was the cheapest wireless camera in the store, and I really wanted a second camera for the living room.
My husband helped me twice- to show me where to plug it into the router at the beginning, and to to tell me where to place the wireless key on the DLink page when I was setting up the wifi.
I used the first DLink MJPEG URL from the page that was linked off the "Getting Started" page on this site and it worked like a champ. Also used the D-Link DCS-930L set up video on You tube for the mac.
So- for less than $75 (app and 2nd camera, aside from my iMac) I now have a two camera security set-up that runs off my iPhone (luckily, I have the 166 IP) and wireless iPad- and sends me alerts, and can be set with schedules and to ignore the lower levels of rooms where the dog would set them off.
Wonderful, wonderful app, amazing documentation!!! I feel like a tech guru
