Camera view shows transparent object This is how my imported stl looks inside the view port in Blender 2.92:

When I view it through the camera it looks like this:

The object seems to be transparent which is not what I want. Any suggestions on how I can make it look like in the view port?
Edit:
Please note that I want to create a svg from the front view of the object. This is why I set the camera far away from the object and increased the focal length, to obtain straight object lines:


It seems to help when I switch from perspective to orthographic:

I am still not sure which camera settings I should choos for my use case (create svg in Blender's Freestyle addon). I thought of having a tele camera and therefore choose the perspective view with a high focal length. Which settings do you suggest?
This is just because you are viewing it from the front. Move the camera a bit in any direction, and it should look better. You could also give the text a different color in rendering. It isn't transparent, just hard to see
