How much does rhinoplasty CCTV recording cost?

I'm going to have surgery
 at a hospital in Seoul
 , and since it's a hospital level, they have CCTV installed,
 but they didn't mention CCTV at all during the consultation.
 
I'm going to record the surgery for safe surgery.
 I heard there's a hospital that asks for a fee for recording, so
 I'm going to go to the hospital and tell them.
 
I think it is very unfair to ask for a recording fee instead of a viewing fee. I heard
 that there are places that ask for a recording fee of 300,000 to 800,000 won instead of a viewing fee of 100,000 won. Is it legal to charge a recording fee from a hospital
 ? I wonder how much the recording fee will be if asked!
 

+ Below is a news article.
 Each hospital has requested CCTV recording, but it cannot be viewed, and even if it is recorded, it can be viewed and erased on the spot, or
 recorded with a cell phone instead of CCTV, and the hospital demands 800,000 won for recording, etc., etc.
 They are very strict! It would be nice if you could tell us about the hospital that had the surgery or agreed to the surgery with CCTV installed.
