GigE camera Mako: recognized via gigecam or videoinput, but (gige) preview times out, snapshot (or getsnapshot [if videobject] returns empty image

Hi,

I have a Mako G-234B GigE camera, connected to a win10 laptop.

The camera is seen without problem if using the standalone "Vimba" application that came with the camera, and can see the live camera images on my PC screen.

Under MatLab, I am presently unable to get any images from this camera.

I have tested two routes (either gigecam, or by videoObject that both failed). here are the code I typed on the console, and the corresponding messages:

(A) Test via VideoInput:

hwInfo = imaqhwinfo('gige')

hwInfo = AdaptorDllName: 'C:\MATLAB\SupportPackages\R2016a\toolbox\imaq\supportpackages\gige\adaptor\win64\mwgigeimaq.dll'

    AdaptorDllVersion: '5.0 (R2016a)'
          AdaptorName: 'gige'
            DeviceIDs: {[1]}
           DeviceInfo: [1x1 struct]

>>videobject = videoinput('gige', 1, 'Mono12')

>> triggerinfo(videobject)

What is your advice ?

Maybe your windows firewall is blocking Matlab. Go to your windows firewall settings. On the list of settings to the left, click “Allow an app or feature through Windows Firewall”. Look for a Matlab entry and allow it. Try the camera preview again.
