The best troubleshooting questions follow the signal path

Most camera problems become easier when they are separated into layers: power, network reachability, authentication, stream protocol, codec, VMS configuration and finally analytics. Jumping directly to software settings can hide a cabling or camera problem; resetting hardware too early can erase useful evidence about the original configuration.

Use the guide to isolate the layer that is failing

SmartVision sits above the camera and network layers, so first confirm that the camera has stable power and can be reached locally, then validate ONVIF/RTSP and codec settings. Only after the video stream is stable should recording or AI be tuned. Start with camera connection, network setup or ONVIF/RTSP depending on the symptom.
