How do I use the AI Perception Teams?

I have perception component in character class, and everything works fine for me. And it is easier to update character states instead of passing them from controller.
Can you explain the difference between using perception component in AIController and Character?

Sure!

In the AIPerceptionComponent, when it is Registered, it casts the result of GetOwner*()* to AIController and sets it to the AIOwner property on the Component.

*AIOwner *is the target it uses to get FGenericTeamId for the **AIPerceptionComponent. **Without that reference, the component will always return FGenericTeamId::NoTeam.

FGenericTeamId UAIPerceptionComponent::GetTeamIdentifier() const
{
    return AIOwner ? FGenericTeamId::GetTeamIdentifier(AIOwner) : FGenericTeamId::NoTeam;
}

It is also used to set the IsHostile property on Structures passed up to blueprint:

PerceptualInfo->bIsHostile = AIOwner != NULL && FGenericTeamId::GetAttitude(AIOwner, SourcedStimulus->Source) == ETeamAttitude::Hostile;

So, by attaching the AIPerceptionComponent to a pawn, it will always be FGenericTeamId::NoTeam, and will aways have Neutral Attitude. It is however still useful for detecting sources.
