I settled on focusing on the Foscam FI8910W which streams MJPEG only. I verified the stream address with Foscam and followed the tutorials.
I tried both motion and generic IP. the camera was not detected, so no P&P.
I also tried the D-Link DCS5222L which was P&P, but no picture showed up either (chose the 5300 at the prompt0. I proceeded to install it manually as motion and IP, but neither worked either.
I can see the pictures using the stream address in a browser, so that's verified.
I tried various combinations in the configuration, passed credentials via the address and also via the user/pwd entries, port in the address or in the port field,... nothing has worked so far, so I'm beginning to wonder what I'm doing wrong (assuming I'm at fault).
What could cause an IP camera NOT to work? My understanding from reading was that just pointing to the stream would display it. What am I missing? I'm trying to understand.
My other question would be, what needs to happen for the images to show (this one is so I can update the documentation).
