Time Synchronization of Multi-view event cameras #1

Hi, there. Thanks for your work for Multi-View Action Recognition based on Event Cameras. I have a question about Time Synchronization across multi-view event camera. I can't found that in the paper. Can you explain more details of that?

For synchronizing multiple event cameras in our multi-view action recognition setup, we've employed an easy indirect triggering mechanism instead of using the external control interface of Celex-V. We connected two cameras to a single laptop and linked three such laptop setups via their controlling mice. When one mouse is clicked to start or stop recording, the same command is sent simultaneously to the other mice, triggering all cameras connected to these laptops to start or stop recording at the same time.
