Add collision to the camera withoyt springarm

Hello everyone.

So, I have a blueprint which is my character, as seen in the image below:

And my problem is that I can’t add collision to the camera.
The CapsuleComponent has colision that works perfectly, but how about the camera? I’ve tried to add a CollisionBox as child (or parent) to the camera right in front of it with no success. Also tried to add a static mesh (as child) that has a collision mesh, but also with no success.
I’m trying not to use the spring arm 'cause it doesn’t gives the effect that I desire.
What I’m trying to achieve is that the camera will move towards the cube with the mouse wheel and if something is in the way, it will block the camera movement.
Does anyone has any idea of how I can do that?

Thanks for your help!
