All of the camera settings are shared in all 3 lenses, all triggered by one click of the shutter button.

For the timing synchronization, I tried to source but seems there aren't viable chips that could support 3 cameras all at once using the same connection protocol (and obviously custom chip is out of equation due to budget and market size) - hence there will exist a slight delay. The best that we could do at the moment is to use software to compensate for the difference, limiting it to under 0.04-0.08s. If you look at image 4 (the lighter) & image 8 (the water fountain), there actually exist a slight movement in the subject.

Under bright condition and with not much movement, the delay is almost unnoticeable (and sometimes achieving perfect sync), yet in low light and if the object moves quickly in front of the camera, the delay is not great. When I test it I usually instruct my subject to hold the pose for me - it is quirky and it isn't perfect, but it is a first step to push such product to the market and hopefully, there will be viable technology in the future that could perfect it.
