CCNVR

System architecture

From device onboarding to recording storage and playback, CCNVR is built on a modular architecture.

Features

From device onboarding and live view to recording playback and system operations, one process handles it all.

• Multi-protocol device onboarding

  Connect over ONVIF auto-discovery, RTSP, RTMP and GB28181-2022, compatible with network cameras and recorders from major vendors.

• Live view streaming

  Delivered over WebRTC, HTTP-FLV and HLS for millisecond-level low latency, with built-in HEVC software decoding fallback.

• PTZ control and two-way audio

  Pan, tilt, zoom and preset control over GB28181 and ONVIF, plus two-way voice talk on GB28181 channels.

• Recording plans and storage

  Continuous and event-triggered recording modes, with weekly schedules plus configurable retention days and time zone.

• Timeline playback and export

  Jump to any moment with calendar and timeline scrubbing, then export and download the selected clips in one click.

• Alarms and AI events

  Receives GB28181 priority 1-4 alarms and multiple alarm types, with AI event detection (person, vehicle) and confidence filtering.

• Monitoring and logs

  Live CPU, memory, network and disk metrics, plus recording coverage, write rate and per-channel usage. Logs can be filtered and downloaded.

• Licensing and online upgrade

  Activate with an offline license file and upgrade online or offline, with signed package verification and automatic rollback on failure.

H.265 and our player

Browsers don't always support H.265 natively. We wrapped xgplayer into a player that decodes on the GPU when it can and falls back to WASM when it can't — one API for FLV, HLS and MP4.

• Same quality, half the bandwidth

  H.265 reaches H.264 quality at roughly half the bitrate, which saves bandwidth on the wire and disk space for long recordings.

• Hardware decoding first

  Where HEVC is supported, decoding runs on the GPU: low CPU usage and smooth multi-stream preview.

• WASM software fallback

  Without HEVC hardware support, a WASM decoder loads automatically — no plugin, no interrupted playback.

Works with major camera brands

Connect over standard protocols such as ONVIF and RTSP. CCNVR works out of the box with network cameras and recorders from Hikvision, Dahua, Uniview, Tiandy, EZVIZ, Axis and other major vendors.

Hardware and performance requirements

Choose a configuration based on the number of cameras. CPU and memory determine concurrent preview and transcoding capacity, while storage depends on the bitrate and retention days.

Note: the values above are minimum reference configurations. A 1080P recording takes roughly 1 GB per camera per day, so reserve disk space according to your real bitrate and retention days. We recommend an SSD for the system disk and HDDs for recordings.

Ports to open

Allow the following ports in your firewall when deploying. Ports marked as optional are only needed when you use the matching protocol for device onboarding or streaming.

16198 is the internal streaming API. Keep it closed to the public internet.

With Cloudflare or another CDN, only HTTP(S) can be proxied (orange cloud). RTSP, RTMP, WebRTC and GB28181 require a DNS-only (grey cloud) hostname or a direct connection to the origin IP.
