Setting Up Multi-Presenters

Welcome back.

So far, we've covered using a tracking camera

and adding a static view camera for a whiteboard, perhaps.

But what if we want to do different things depending on how many people are on the stage?

Well, you can imagine a scenario where

you're tracking camera is so far zoomed in on the presenter that

it can't even see that there's someone else who's walked onto the stage.

Now, for this reason,

we can add a conductor camera.

This is a third type of camera which can be used to analyze the entire stage at all times.

And it does this using the second channel of a Seervision server.

This means that our camera can always

see how many people are on stage and you can take different actions

depending on the number of people.

Let's take a look at how we do that.

As we mentioned earlier,

a two channel Seervision server is running two  

completely separate instances of the Seervision .

We can access that second instance by putting “/2” at the end of the IP address

or by pressing the button at the top of the Seervision user interface.

I've already linked this second instance to my conductor camera

and you can see that the conductor camera has a really good view of

the whole presentation area at all times.

This is perfect because we can add a trigger zone to keep track of all people on stage,

even when the tracking camera is fully zoomed in.

Of course,

because there are displays inside the trigger zone.

We've also added a couple of exclusion zones to

make sure people shown on screen do not trigger events.

We'll also add a conductor camera to our Seervision plug in properties

and then open up the plug in to see what's changed.

You can see that the setup page lets us add another series,

an IP address and another instance for the conductor camera.

And we also have a conductor cameras page,

which looks exactly the same as our tracking cameras page,

because of course both of these cameras can have trigger zones that

interact with the plug in in the same way.

From the setup page,

we can now link the plugin to the second instance on our Seervision server,

and we're going to do this in exactly the same way we did in the basic presenter tracking video.

With everything connected,

our first job is to create an event for

when there are multiple people in that big trigger zone.

This will be when someone enters the zone in addition to the first presenter.

So we'll set the event type to entered and the persons to 2+.

This will work for any number of people above one.

For the action,

we're going to recall a position container which frames the entire stage.

We also need an event for when the second presenter  

leaves with only one presenter remaining.

So let's change the event type to leave and the persons to one

because there's one person remaining after the event.

When this happens,

we want to go back to tracking on the tracking camera.

So we'll choose our tracking container here.

Note that with these two events,

we're recalling tracking and position containers on camera one,

but the triggers are from camera two,

which is the conductor camera.

So let's see it in action.

Here we have one person being tracked.

Note that there is another person on the display,

but that's not doing anything because it's in an exclusion zone,

which is why that person has a red box around them.

Now we see the second presenter appear.

You can see that as soon as they're recognized and their bounding box turns green,

we also get a trigger LED in Q-SYS for the entered event.

Immediately, you can see the tracking camera

moving towards the position container we set up to frame the whole stage.

Now once these guys have finished chatting and the second presenter leaves,

we can see that we get a triggered LED for the leave event

and the camera starts moving back towards its tracking container.

So that's how you set up multiple presenters.

Now you've covered a lot in this course,

hardware and software getting connected to Q-SYS,

basic tracking, adjusting the tracking,

exclusion zone, static view cameras, multiple presenters,

and you're one assessment away from being Seervision commissioning level one certified.

Now, remember, once you get certified,

you still need to sign up for Seervision commissioning  

level two in order to be able to commission,

Seervision systems in the field.

There, you'll learn a whole lot more,

including adding in ACPR and auto framing to Seervision systems.

I'm sure we'll see you again soon, but regardless.

Thank you so much for coming to Seervision Commissioning Level one.

I hope you've learned a lot,

and we look forward to seeing you again.

Thanks so much.
