some camera support different mode of fps and resolution for example 30 fps 300*400 / 25 fps 600*800  15 fpc 1200* 1800
when you call a camera with imagdx the default one start to act if you want to switch to different mode of camera you have to change the mode
labview example have a example of  reading a camera mode and setting the option try to test it

Hi Hatef

my GigE camera support three modes of fps and resolution for example 250 fps 640*480 / 488 fps 640*480  1076 fps 256* 256, the system calls a camera the default one (250 fps 640*480) start to act, I want to switch to different mode. 

I have tried IMAQdx Enumerate VIdeo Mode to set the height and width, but it cannot works. Also, the IMAQ video out display mode only have 640*480、800*600 and high resolution which I don't need.

So do you have any suggestions for change the camera mode?

Thanks

Hi likecoco
you ask two question and I think it is better to create new topic about it
you can change camera mode with property node but any time you change it it could a bit delay on that time
for second question you have use IMAQ Remote Display Options VI
to wire quality and also use JPEG compression
