Streaming Intelligence

Smart Transport Under the Hood

Automatic TURN relay, staggered connection management, per-connection adaptive quality, and intelligent codec negotiation keep every stream running smoothly.

Automatic TURN Relay

WebRTC connections automatically fall back to TURN relay when direct peer-to-peer fails. TCP-only TURN transport ensures 4K cameras work behind restrictive firewalls.

Staggered Connection Management

Connections are established in staggered batches to prevent thundering-herd problems when loading large camera grids simultaneously.

Per-Connection Adaptive Quality

Each viewer connection independently adjusts resolution and bitrate based on available bandwidth, ensuring optimal quality without buffering.
