Trigger event in sequencer with camera

Hi everyone,

I’m a student in NAD university and I need to do a cinematics for my last project.

We need to trigger some event (3) minimum in the sequencer.

We setup the event with trigger box but because the caméra isn’t a actor or a character the trigger isn’t activated. (pretty logic) but what is the best way to trigger those event in the sequencer in the moment that we want?

I hope to have explain correctly my problem.
I can give you more informations if you need it.

Here’s some documentation about how to trigger events through sequencer:
