Two cameras at the same time Lab view (NI MAX)

[AurelioSilva]

I have two similar Point Grey Firefly MV cameras. I need to use them simultaneously in LabVIEW, but NI MAX only detects one at the same time (the two cameras are detected properly separately). I think that NI MAX identifies both camera as the same camera, but I dont know how to change the name of one of those cameras, or maybe change the serial number. Also NI MAX gives the same serial number to both of them. I would apreciate your help

Thank you.

May be a camera problem.  What sort of interface are they?  We've got 24 Axis Ethernet cameras, plus several miscellaneous USB cameras, and MAX sees all of them.

Hi Aurelio,

This is a commom issue for USB Cameras. Once IMAQdx calls the camera driver to acquire image, if the camera driver cannot acquire from 2 cameras, IMAQdx cannot acquire from 2 cameras too.

You can ask to camera vendor about how the camera driver works.

Yes. It was a problem with the driver of the camera for directshow applications. It doesn't allow to work with two cameras simultaneuosly.

Thank you.
