Device Connection

Establish and manage connection between image acquisition device and MATLAB®

To connect to and acquire images from any supported hardware, you can use the videoinput object. Use the imaqhwinfo function to determine your device adaptor names. You must install the appropriate support packages for the adaptors to show up. See Installing the Support Packages for Image Acquisition Toolbox Adaptors.

If you are using GigE Vision hardware, see the GigE Vision Device Configuration section for information about setting up acquisition with GigE Vision cameras.
