How to stop the camera from going through a semi-transparent part?

I made a building in Blender that has windows. The windows are flat planes combined into one mesh, have 0.85 transparency and their material is SmoothPlastic. They have CanCollide and CanTouch enabled. For some reason the camera can go through them. How do I stop it from doing that?
