How to differentiate two kinds of entities with the same components?

[silent granite]

I have an entity for my player and and entity for the enemy. Both of them have [PhysicsVelocity] and [Speed] as components. (Speed just stores a single float)
This 2 components are inside the PlayerMovementAspect.
Then i have the PlayerMovementSystem which iterates on the entities with the PlayerMovementAspect, takes keyboard input and change their velocity.

Of course, this moves both the player and the enemy.
How can I/should I differentiate both of them so I move only the player?

It feels like i'm having a problem with architecture other than with ECS code knowledge. Should i separate the Speed component into a PlayerSpeed and an EnemySpeed one? Should I incorporate the speed float inside other components that are exclusive to the player or the enemies? Am i missing something else?

I'm new to ECS and my knowledge basically comes from the 1.0 tutorial by CodeMonkey and i couldn't find whats the right solution anywhere, so sorry if it's a dumb question.

something like a Player tag would be a general approach

or if multiplayer you might need LocalPlayer as well to differentiate between other players and yourself

the game is single player so just the Player tag does the job
