low latency browser streaming for IP cameras ?

powerstreamer said:

hey there, has anyone used WebRTC for to stream ip cameras feeds with very low latency in a web browser ? i am currently evaluating solutions like red5, i would be interested if anyone has used or if there is any other alternatives.

I have a PWA GitHub - tylerransdell/onedoor: Tactical‑speed door comm and control — SIP audio + WebRTC video, fully local. that focuses on the real-time aspects of home security and automation. It’s a work in progress and development is slowing down a little now as I focus on other things, but you might find it fills in the gaps between NVRs and the present. I generally recommend lower res streams and don’t allow zoom because detail isn’t the point in real time. Action is.

I use a modified go2rtc build to stream video because I’m already using it as a camera interface. I use JsSIP for audio to force browsers to respect audio latency significantly faster than video latency.

I think the tricky part with IP cameras is getting the video into a browser without adding too much buffering along the way. Most cameras already provide RTSP, so having a lightweight gateway handle the conversion to WebRTC makes sense, especially if you want to keep the camera setup unchanged.

For remote viewing, I’d also look at where the stream is being decoded and how much buffering the player adds, since both can affect the overall delay. Ant Media Server is another option worth exploring for RTSP-to-WebRTC workflows.
