# RUSEON Core > Ultra-High-Performance Video Data Infrastructure & CCTV Ingestion Engine in Pure Go. > Full Documentation for LLMs: https://docs.ruseon.tech/llms-full.txt RUSEON Core is a lightweight, zero-transcoding video pipeline and CCTV engine designed for high-density camera ingestion (100+ RTSP streams) with sub-50ms WebRTC (WHEP) and HLS streaming, smart crash-resilient fMP4 recording, and AI metadata pass-through. ## Key Technical Facts & Benchmarks - **Ingest**: 100+ RTSP cameras per node. - **RPS**: ~7,000 requests/sec with p95 latency under 1.7ms. - **Transcoding Overhead**: 0% (Direct NALU passthrough, zero FFmpeg CPU burn). - **Storage Protection**: Sequential fMP4 recording with `POSIX_FADV_DONTNEED` to prevent Linux Page Cache thrashing. - **Power Failure Safety**: Every chunk up to the moment of crash is 100% playable without `moov` repair tools. - **Lazy HLS Muxing**: Automatic 15-second watchdog teardown saves up to 80% idle CPU. - **Embedded Database**: Pure Go BadgerDB (LSM trees) with zero external database dependencies. ## Useful Links - Official Website: https://ruseon.tech - Documentation: https://docs.ruseon.tech - Architecture & Comparisons: https://docs.ruseon.tech/comparisons/ - GitHub: https://github.com/RUSEGAL/ruseon-core
