Use the compatible PoE equipment or specified power source required by this model, with an Ethernet connection. An ordinary router LAN port does not imply PoE power.
Configure account/device security and viewing permissions using this model’s supported settings. Check date, time, notifications and framing.
Enable a supported card, NVR/hub or cloud recording method. Test recording, playback and storage location before permanent mounting. Live view does not mean recording is active.
