Thanks for contacting National Instruments. I just wanted to add a brief comment on this thread. There is definitely some good information on here. Generally if you do need a high performance acquisition and want to do this in LabVIEW or with NI-IMAQ then by far the easiest way to go is to use an NI Frame Grabber to assure that everything will communicate together properly. The NI PCI-1411 accepts S-Video input, so that could be one option if you are looking for other hardware.
With that said, using it in LabVIEW will all depend on the hardware and software of your 3rd party frame grabber and other software you may have available. If the manufacturer provided a VI Library or a set of C/C++ functions for acquiring images from that hardware, then you can try to call those in LabVIEW to see if you can get the image that way. If not, then you can try to use ActiveX to communicate with the device as well, but from what I've heard and what people have posted here that does not always provide the best performance. I do not know of any 3rd party software that would provide you with that functionality through ActiveX. If you have any more questions on our National Instruments products or anything else, then feel free to let us know. Regards, Michael Applications Engineer National Instruments
