Sync multi cameras

Hardware ZED Mini
1

Hello there,

I have two ZEDX MINI cameras and a Orin AGX and a capture card quad; and I want to sync these two cameras .

I read all documents and SDK Readmes, I am still confused about the sync method.

Here is my questions:

1、How can I use a Trigger signal to trigger the two cameras? I read this page,ZED Link Mono GPIO Triggering - Stereolabs, But it says the function is not available now? When Can I use this mode? When it can be used, Can I randomly set the trigger signal? Like 1-30fps continuously adjustable?

2、If I use the sync method like this page shows :GitHub - stereolabs/zed-multi-camera: ZED SDK sample with multiple ZEDs, what is the laggest latency between the two cameras?

Hi @wangchunyi120
All the cameras that are connected to the same 4-wire GMSL2 port are natively hardware synchronized. You must not enable synchronization.

On the ZED Link Quad, you must enable synchronization only if you connect cameras to the two different 4-wire ports.

The synchronization accuracy is 15 µsec
