Is this need to be concern?

Hello,
here is a prettier view of the same result: developers.facebook.com/tools/debug/og/o...s%2F114-camera-terms

Those are only warnings stating that those tags are missing, and now you have to choices:

1. fix those errors and be on top (control) of how FB sees your site
2. leave those tags unchanged and let FB use whatever it see fits (some default text, description, image, etc)

bottom line, those are just warnings and not errors.
