Right now, I am not aware of any cheap ip camera that can stream its H264 video to a regular web browser, with sub 500 ms latency. All manufacturers seem to have moved to an app, I guess they can show an RTSP stream in that way.
Older ip cameras had MJPEG which you could view in the browser, but that is really inefficient w.r.t. bandwidth.
When the Pan cam was initially released I bought a couple of them and hacked on them for a while. examining the original firmware quickly revealed they were using WebRTC for the video. At least at the time almost all the cameras based on the Ingenic T series chips used the same backend service. It has been a couple of years so my memory fails on the name. The marketing material for the service mentioned the use of WebRTC.
