  "account": "Remote desktop tools often suffer from input lag and latency jitter due to cloud-relay architectures. This article examines why direct P2P pipelines using WebRTC and native desktop duplication APIs can achieve sub-50ms latency. In traditional client-server remote control, video streams travel from source to relay data center to destination, adding 60-150ms of unavoidable latency. Bandwidth saturation and transcoding overhead further degrade quality. Privacy concerns arise from third-party servers processing active desktop feeds. Direct WebRTC peer-to-peer streaming eliminates this latency by acting only as a signaling/rendezvous coordinator. Once the direct socket is established via STUN, media and input data flow directly between endpoints over encrypted DTLS-SRTP, avoiding middleman servers. Native capture APIs like Windows' Desktop Duplication API (DXGI) and macOS' ScreenCaptureKit achieve sub-50ms glass-to-glass latency by acquiring frames directly from GPU memory, resulting in frames processed without unnecessary host memory round-trips. P2P architectures offer speed and privacy but require engineering for symmetric NATs, congestion control, and robust encryption. Conexa Remote implements these principles with sub-50ms latency, clientless ad-hoc connections, a floating concurrent capacity model, and EU-hosted infrastructure.",
  "summary": "When building or selecting remote desktop tools, developers and IT administrators frequently hit a common wall: input lag and latency jitter . In this article, we’ll look under the hood at why traditional cloud-relay architectures introduce latency bottlenecks and how modern direct Peer-to-Peer (P2P) pipelines powered by WebRTC and native desktop duplication APIs can achieve sub-50ms…",
