I am looking to capture images simultanously using 2 picameras (tried USB the FPS is low). It seems like there are 2 options:

Which of these 2 options would be better? I want the images as close together from the 2 cameras as possible as well as getting good FPS.

The compute module allows 2 x 720p@30 fps. The multiplexer board does not allow simultaneous operation of multiple cameras, only a round-robin scheme. Switching between cameras will take some time and interrupt the video feed.

  • Do you know if the picamera can plug straight into the io board or do I need to buy an adapter?

I saw this in the latest MagPi: https://stereopi.com/

It looks like it is perfect but know no more than I read in the magazine.
