can anyone tell me what i can use that's the size of a GoPro and can live stream to OBS or similarly work as a wireless webcam and costs less than a hundred pounds or doesn't need a monthly subscription to do so 
"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 Your cellphone, NDI camera app and NDI plugin in OBS. I've streamed with 3 camera rig foe years and it's made of old phones.
The image quality is fantastic, depending on the phone and the lag is minimal.
@apzpins my phone sadly is not the size of a gopro and it does not have a tripod screw mount (cheap spring-loaded finger traps that accidentally hold down the power button half the time do not count)
@mavica_again Shame, I experimented with a lot of different wireless and wired solutions for a use case where the PC is 5-15 meters from the camera rig and the phones beat everything each time.
@apzpins i have the paid version of ip webcam pro, i'm well adept at using phones as pc cameras. it's great and physically unwieldy and i do not have a phone for which it can use the wide lens on it (i have already emailed the developer asking for this feature without an answer)
@apzpins also i would like a camera that does not spend battery into heat through the incessant wheelspinning of android
@mavica_again Sorry for the YouTube link, but is this helpful?

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