Took a while, but I finally figured out the RTSP URL format of the lightbulb camera I'm playing with. It's not documented anywhere.
Anyhow, if you have a #Kerui Lightbulb fisheye camera: rtsp://admin:[pass]@[ip]/h264/ch1/main/av_stream is the URL format you want.

@joeyh Correct. It's marginally better than hanging passwordless on the network, but not by much.
Octodon is a nice general purpose instance. more
