Hi Mirek,

This means that the vendor SDK is unable to find any Point Grey/FLIR cameras.

The Flea2 is a Firewire camera.  In principle that is supported by the FlyCap2 SDK that ADPointGrey uses.  However, I am not sure if anyone has actually used a Point Grey Firewire camera with ADPointGrey on Linux, and almost certainly not on a Ubuntu 20.

Firewire cameras are not supported by the new FLIR Spinnaker SDK, so upgrading to that is not an option.

Is replacing the camera an option?  New GigE or USB-3.0 cameras with much better performance than the Flea2 are less than $500.

Mark

Subject: Area Detector and Flea2 camera problem

Hello,

I am using the latest Area Detector R3-10 on Ubuntu 20.04 focal (x86-64).
Unfortunately the Flea2 camera which is connected to the computer is not detected:

Startup script:

Does anybody have an idea what might be wrong?
