Key Considerations for WebRTC on Embedded Devices

Why WebRTC Is Chosen

For viewing AI camera footage in real time, WebRTC offers the following advantages:

• No plugin required in the browser
• Low latency via P2P (<200ms)
• NAT traversal (STUN/TURN support)

Embedded Implementation Considerations

Signaling Design

Establishing a P2P connection between an embedded device and a browser requires a lightweight signaling server.

GStreamer Pipeline

Optimize the GStreamer pipeline from camera input to WebRTC output.

Coexisting with Recording

Sharing the video pipeline between the recording SDK and WebRTC reduces CPU load.
