cannot choose another webcam which has same name

[lovemachinez]

Dear, all

I have 2 similar webcam plugin with my laptop and want to snap picture from them.(not same time)

The problem is these two camera have same name, so when I want to select and capture with the 2nd webcam, LV always return to capture with the first webcam.

How would I do?

Can I change driver's name of the webcam?

best regards

Did you ever find a solution?

You can change their names in MAX (Measurement & Automation Explorer). Go to "Devices and Interfaces", then "IMAQdx" (this might take a few seconds to show up as it scans for cameras), then your cameras should be listed - you can right click on them to rename them there.

Had that problem. I believe it is because the Windows software was never made to work with multiple cameras at once. Each identical camera is listed in the Windows Registry under identical names. I believe you can modify the registry, but that is not a satisfactory solution.

Really? I've got it working just fine on my PC.

I wonder: are you using NI-IMAQdx? Or something different?

I think I’ve seen it with NI-IMAQdx. It’s only with some USB cameras, such as webcams. And it is only when using identical models; one can use multiple cameras of different models, because they go into the Registry under their model names.

If you're using IMAQdx, it uses the names listed in MAX, not the registry, so this shouldn't be an issue.

Cameras showed up in MAX no problem, but both MAX names would, if selected, lead to images from only one of the cameras. It’s was driver issue, at a lower level than MAX.

Ugh - that's ugly.
