Things to try

Things you can try to narrow down where the problem might be.

Restart and reconnect

Always try restarting the system first, this resolves many transient issues.

Also check all cables by unplugging them and plugging them back in.

Restart the Nx Meta Mediaserver

For the plugin to be detected after install, restart the Nx Meta mediaserver. Open <Server IP Address>:7001 in a browser, go to the Servers tab, and click the restart button.

Reinstall the Nx Meta Mediaserver

First, remove the existing plugin by following the uninstall instructions. Then follow the install instructions for a clean installation.

Try another version

There might be a newer version of Nx Meta or Nx EVOS available. The new version might have improved functionality. Download the new version and install it to see if your problems are solved.

Check if the latest beta fixes your problem, or if it worked in a previous release.

• Nx AI Manager plugin - see the install instructions.

• Nx Meta Mediaserver - check if there is a newer version or a beta available.

• Nx Meta client - check if there is a newer version or a beta available.

Try another model

See if you can install another model and see if it gives correct results. Verify that the model is downloaded and running.

Try another camera

Check if the model works on another camera. If no other camera is available, you can point the camera at a different scene.

Try to reset an unresponsive USB camera

USB webcams on Linux can enter sleep mode and become unresponsive. To reset one remotely, log in to the machine's console and use usbreset to list USB devices. Reset a specific device with its bus address:

user@system: usbreset 00n/00m

Try a test camera stream

If you cannot swap the camera, use a video feed instead. The Network Optix test camera tool lets you stream a video file as a virtual camera, useful for testing a specific model against known footage.

Try another computer

If you have another computer available, install the Nx Meta Mediaserver or Nx EVOS and check if it works on that system. The Nx AI Manager in Nx Meta and Nx EVOS can run on systems like the Raspberry Pi or the NVIDIA Orin Nano and on many standard PCs and laptops.
