Can I synchronizing two OV9281 camera modules each on a separate Rasberry PI?

I would like to use two Rasberry Pi 4 boards, each with an OV9281 camera module and synchronize the two cameras. Is that possible?
Do I need some special configuration files for this?


This may not be perfectly synchronized.
You may want to try our Camarray ov9281

They are to close together. And we will need some processing power per camera.
The OV9281 has a sync pin. So why can I not synchronize them?
