video frame sync for oak-d pro poe

Hi all,

i am using a four camera system with 2 pro poe and 2 pro w poe.

I would like to sync the video frames at 15fps on all the cameras.

As i understood, i need a 15Hz trigger signal on the FSYNC input , which goes from 0 to 12V to trigger on the rising edge.

I am thinking of a 12V pwm signal with 50% duty cicle, would that work ?

On the documentation i read 1V8 and also 12V in the FSYNC image, what is the correct voltage ?

In the code i have to activate the trigger for all the camera but i leave the 15 fps setting or not ?

Thanks

I think the only thing that matters is the rising edge, so width shouldn't be a problem.

10-24V for external trigger.

You need to set all to cam1.initialControl.setFrameSyncMode(dai.CameraControl.FrameSyncMode.INPUT).

Thanks,
