Reolink D340W (Video Doorbell WiFi)

D2 Cloud-Optional — Full function with the router off.

The unplug test

Unplug the router and the doorbell keeps doing its job: press the button and the chime still rings, because that pairing runs on its own short-range radio, not your internet connection. Motion and person detection keep running on the camera itself, and video keeps recording to a microSD card if one is installed — Reolink's own support documentation confirms both continue with no internet connection. On the local network you can still pull the live RTSP stream and the ONVIF feed into your own NVR software — Frigate, Blue Iris, Synology Surveillance Station. What you lose is anything that has to leave the house: push notifications to your phone, live view from outside your network, and Reolink's optional cloud backup.

Why this tier: Reolink operates a cloud and app for this doorbell (My Cloud backup, push notifications, remote live view), so it is not D1 — but Reolink's own setup guide for WiFi cameras with no LAN port shows initial configuration completing with only a local camera password and a device name, no cloud account login step. That guide's ten steps were re-read end to end for this record: scan the UID, choose 'Wi-Fi Not Configured', enter the network password, let the camera scan a QR code, then 'Create the password for your camera' and name it. There is no registration or sign-in step anywhere in the flow, and the one credential it does create is a password stored on the camera — a local credential, not a Reolink account, by the test in PRINCIPLES. The D340W is a Wi-Fi camera with no LAN port, which is exactly the population that article covers. Core function — detecting a visitor, ringing the chime, and recording video — is confirmed by Reolink's own FAQ to keep working with no internet connection at all, and the camera exposes standard RTSP and ONVIF over the LAN for a recorder the owner controls.

Self-hostable full — fully replaceable on your own hardware
RTSP and ONVIF feed directly into Frigate, Blue Iris, Synology Surveillance Station or ZoneMinder on hardware the owner runs, same as Reolink's other cameras. As with the RLC-810A, Reolink's on-device person/package detections are exposed through Reolink's own software rather than guaranteed over ONVIF, so a third-party recorder reliably gets the video but not necessarily the AI event tags.
