NVR Command Center is an ultra-low-latency, GPU-accelerated multi-camera RTSP IP Camera, CCTV, NVR, DVR, and XVR surveillance video wall and monitor for Linux and Ubuntu, built in Native Rust (eframe/egui + OpenGL) with zero-probe FFmpeg workers and built-in Cloud P2P remote tunneling.

Stream 1 to 32 concurrent security cameras 24/7 with < 0.9s parallel startup, < 80ms glass-to-glass live latency, zero stream drift, and ~65-110 MB RAM on both local LAN and any remote internet connection.

Native Linux Alternative for CCTV & NVR Client Apps:

• Dahua: SmartPSS (Smart PSS), DMSS (gDMSS / iDMSS), Easy4ip (Easy4ipCloud)
• CP Plus (CPPlus): KVMS Pro (KVMS), gCMOB, iCMOB, InstaOn, EzyKam
• Hikvision & HiLook: iVMS-4200 (iVMS), Hik-Connect (HikConnect)
• Amcrest: Amcrest Surveillance Pro, Amcrest View Pro, Amcrest Cloud
• Reolink, Lorex, IMOU (Imou Life), TP-Link Tapo & VIGI, Uniview (UNV / EZView), EZVIZ, Axis, Foscam, Ubiquiti UniFi Protect, ONVIF IP cameras, and RTSP feeds from Frigate, ZoneMinder, Shinobi, Agent DVR, Blue Iris, or Home Assistant.

Key Architecture & Features:

• Zero-Lag Kernel Pipe Burst Drain (ioctl FIONREAD) keeps 0 buffered frames for < 80ms real-time glass-to-glass latency with zero inter-camera drift
• Built-in Cloud P2P Remote Access (Easy4ip / InstaOn / P2P Serial Number): view your NVR/DVR/XVR cameras from any outside Wi-Fi or mobile hotspot with zero router port forwarding and zero extra home hardware
• Automatic LAN <-> Cloud P2P & Tailscale detection and 1-click Top Bar switch
• Instant < 0.9s parallel multi-camera startup (H.265 / HEVC & H.264)
• GPU OpenGL UV shader digital zoom (1.0x - 5.0x) and click-drag pan at 0% CPU
• Per-camera [SD]/[HD] stream quality toggle and [Single]/[Grid] view buttons
• 4.5-second frozen-socket watchdog for 24/7 unattended video wall stability
• Patrol Mode auto-rotation, 12-camera composite wall PNG snapshots, and in-app GUI Settings with first-launch Quick Setup wizard
