Error: "Camera Not Found" in EthoVision XT

This message indicates that EthoVision XT is unable to detect the connected camera.

Solution 1: Check the connections

Ensure the camera is properly connected to the PC. For Basler cameras, refer to this guide: Connecting a Basler Camera.

Solution 2: Install the correct Basler Pylon driver

Check that the installed Pylon Camera Software Suite matches your version of EthoVision XT. A mismatch may cause the camera not to be recognized.

1. Open the Start menu and search for Programs and Features.
2. In the list, locate Pylon X Camera Software Suite.
3. If the version is incorrect, uninstall it.
4. Use the table below to download and install the correct version:

Installation Notes for Pylon 6.x and above:

• Run the downloaded installer.
• Accept the license agreement and choose Custom installation.
• Select GigE Camera Support (for Ethernet) or USB Camera Support depending on your hardware.
• Important: Also select Pylon Viewer and DirectShow Support. Without DirectShow, EthoVision cannot detect the camera.
• Finish installation and restart the computer.
