Issues with moving the camera

Hello!
I am quite new in the 3d world and I am designing a virtual exposition for my company using Blender and Verge3d. I also would like to apologize for my english because it is not my first language.

I was wondering if it would be possible to set a collision to the walls of my exposition in order to stop the camera to go out of the room I created. Sometimes if I scroll too much or try to move my angle, the camera ends up getting out of the ambience of the exposition and I am afraid users won’t know how to get back inside. Is there a way to prevent this from happening?

Thank you in advance,
