Photonvision version: 2024.2.9
Browser: Chrome, unsure of version
Camera: Arducam USB OV9281

To Reproduce:

1. Have camera plugged in
2. Boot up web UI
3. observe placeholder camera
4. Restart Photonvision from web UI
5. Issue is solved

Hello, are you sure that the backend is connected? This will either happen when the frontend hasn't connected to the backend service or the backend hasn't published camera information (usually due to an issue setting up that camera).
