Download and verify
Open the CamBackup Gateway page, choose the matching Linux archive and compare its SHA256 checksum. Follow the included install instructions. The archive includes a reviewed FFmpeg installation helper; it does not bundle FFmpeg.
Open the private dashboard
Start the gateway and open http://127.0.0.1:8844 on that device. Read the generated local administrator password from its private state directory. For a headless Pi, forward that loopback port over SSH from your computer. Do not expose the HTTP dashboard publicly.
Add and test a source
Discover authorised local ONVIF devices or add a supported network source explicitly. Supply the camera credential locally and preview it. Discovery can depend on interfaces and VLAN boundaries. Local previews are source pixels and precede cloud privacy masks.
Pair and import
Get a pairing code. Sign in interactively to CamBackup, open LAN gateways and approve exactly that code. Import selected cameras, which start with recording off. Apply cloud privacy/audio settings and test live and entitled recorded output.
What success looks like
The selected cloud camera receives video through the paired outbound gateway without publishing the camera service on the internet.
If it does not work
Check the local source first, then power, required encoders and outbound connectivity. The gateway has no offline recording or backfill. If you lose its state, revoke the old device before pairing a replacement.
