Hi Ivan,

there exists a driver for USB-Cameras.

It should be possible to use this to grab the pictures.
This driver is not supported by NI and not investigated anymore. So if you have some questions about the driver you only can ask in the forum for some help.
En general you should be aware that the pictures of a webcam are bad quality and for a industrial aplication its far to bad.

I hope this helps you,
Greetins, RMathews

Hi RMathews.

I had read this in the forum, but it gives me problems installing. The message is "You must have vision 7.1 or higher with labview 7.1 or vision assistant 7.1 or higher installed".

My labview version is 8.2.

¿What is the problem?

Regards,
Iván.

Do you have vision installed? As my informations are, you need it to use the usb-driver!

No, i have not installed vision, but i thought that it was not necessary.

Thanks RMathews,

Ivan.
