Most of Blackmagic's external video capture devices are in the UltraStudio line. Unfortunately, none of the UltraStudio devices allow for capturing more than a single video input signal at a time.
You can, however, use one of the multi-channel DeckLink cards (DeckLink Duo, DeckLink Quad, or DeckLink 8K) in an external Thunderbolt PCI Express card enclosure. In that way it is possible to capture multiple video sources simultaneously into a Thunderbolt-enabled laptop.
Keep in mind though that the processors and GPUs used in laptops tend to be lower powered and as a result lower performance than an equivalent desktop or server processor.
So even though you may be able to input multiple video channels into a laptop, you might not be able to handle the processing and encoding of as many simultaneous video streams on a laptop as you would on a more powerful desktop or server machine.
