Field troubleshooting guide
Camera cannot be discovered
Confirm power, link and IP reachability before treating ONVIF discovery as a camera fault.
This is a field-check procedure. The website is not connected to, monitoring, or testing your camera.
When this guide applies
An IP camera is missing from a tester or recorder discovery list.
Initial checks
- Confirm camera power and link.
- Check the tester and camera IP ranges, VLAN, and known camera address.
Follow the symptom
Known IP does not respond
Check: Check addressing, cable, switch port and network isolation with the network owner.
Interpretation and next step: Restore basic IP reachability before investigating discovery.
IP works, but discovery is empty
Check: Check whether discovery is enabled on the camera and whether multicast discovery can cross the current network segment.
Interpretation and next step: Direct IP access with failed discovery narrows the issue to discovery configuration or network filtering; do not assume ONVIF conformance.
