Normally this would not be done on one Machine. If so it is a big one, having enough power for running (parts of) the OS in real time. My suggestion would be to use a small embedded SoC and a OS or programming technique doing hard real time and another one, RPi would fit here from 15$ or so upward, recording and / or streaming video. Regarding data acquisition it is really hard to decide which bus or communicaation port to use if the target measuring hardware isn't known. Many industrial installations use modbus on RS485. > Hoping for some useful replies.
