g = gigecam();   %associate with first available one

img = snapshot(g);  %get a frame

Or you can continue to use videoinput objects. For a working example see http://www.mathworks.com/matlabcentral/fileexchange/46879-gigeacq-m

Undefined function or variable 'gigecam'.

You need to install the drivers.

Note: GigE Camera support requires the Image Acquisition Toolbox

Try:

webcamlist

to see the list of installed cameras. By default, the built-in camera is camera no 1, and other external cameras are camera 2, 3 and so on. Check the number for the camera you wanna use. Then, when creating the webcam object, pass the number (for example the camera number you wanna use is 2) like this:

Cam = webcam(2)

Hope it helps!
