Is there a monthly fee for dash cam?

Excuse me, I was just reading about dash cams and I'm curious about the cost associated with them. Specifically, I'm wondering if there's a monthly fee that comes with owning and using a dash cam? I understand that the initial purchase price is one aspect, but I want to make sure there aren't any additional, recurring costs that I should be aware of. Could you please clarify this for me? Thank you in advance for your help.
