Camera Not Showing
Standing at the aircraft with a camera that isn't publishing, there are three things you can actually do: reseat a cable, power-cycle the camera, or fix an address. The Streaming page tells you which one to try rather than leaving you to guess, and it prints the address it is trying underneath.
What the message means
| The page says | What that means | What to do |
|---|---|---|
| The ethernet cable to the camera | The port has no carrier at all. | Reseat the cable, or power the camera. Nothing about addresses matters until this is fixed. |
| Not on the camera's network | The device has an address on a different subnet from the camera. | Give the port an address on the camera subnet. The setup wizard offers to do this for you. |
| Is not answering | The network is fine, but nothing replies at that address. | The camera is powered off, or it lives at a different address than the one configured. |
| Power-cycle the camera | The camera answers, but the stream has stopped. | It hung mid-stream. Pull its power. Changing settings on the dashboard will not bring it back. |
| Likely changed address | Something answers, but it does not look like the camera that was configured. | The camera moved, usually after taking a new address from a router. Rescan from the fault message. |
| Refuses the connection | The host is up, but the RTSP port is closed. | The port in the address is wrong, or the camera is still booting. Check the port and try again. |
Check the address first
Every fault message prints the address the device is trying. A good share of camera problems are a device looking confidently at the wrong place, so read that line before changing anything: if it isn't the address in your camera's own app, the fault is your configuration and not the camera.
When the camera moved
A camera that took a new address from a router gets the “likely changed address” message, and the fault itself offers the rescan that fixes it. That reopens the camera step of the setup wizard, which searches the reachable addresses and then asks over ARP, so it finds cameras that have moved back onto the subnet they shipped with.
If the camera genuinely lives somewhere the scan can't reach, type its address in by hand. It is in the camera's own app or manual, and on the Tested Cameras page for the models we have checked.
