Hi Bogart,
NI-IMAQ 1394 supports any camera that outputs 8-bit monochrome uncompressed, 16-bit monochrome uncompressed, YUV, or RGB video data and adheres to the IEEE-1394 standards for industrial digital cameras (up to IIDC v1.30, also known as DCAM).
So If your BASLER cameras are compatible with DCAM Standard (version 1.3) you will not find any problem using IMAQ driver.
I hope this help you.
