There’s a frame sync pin on each camera that you can use to sync the video. That said, it’s not really that critical to sync each frame as our default camera is a rolling shutter camera. As such, we aren’t really movement invariant. If you are trying to detect something that’s moving fast you have to use the global shutter camera. Anyway, you can sync each camera to execute python code that triggers the camera capture with a master clock source if you use the global shutter camera.
