I am looking to capture images simultanously using 2 picameras (tried USB the FPS is low). It seems like there are 2 options:
Raspberry Pi compute module 3 with IO board which gives 2 CSI ports(https://www.adafruit.com/product/3442)
A multiplexer CSI add on board (http://www.ivmech.com/magaza/en/development-modules-c-4/ivport-v2-raspberry-pi-camera-module-v2-multiplexer-p-107)
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.
