"just use ip webcam app on an android phone" while i do love the ip webcam app i cannot find an android phone shaped like a gopro with a tripod screw mount
Logitech Brio. I have one, and it does its job very well.
@WarmasterPalak there are at least half a dozen models under the "brio" name, which one do you have? does it have a wide angle lens?
I have a Brio 100. It's small and very easy to use. It might not have all the features you may want, but it is cheap and easy to set up. I don't think that the Brio series has subscriptions (at this time) but it is a good starting point for looking for something inexpensive.
@mavica_again Sorry for the YouTube link, but is this helpful?

Mentions using an Apeman A79 and figuring out the RTSP stream address.
