יחס אות לרעש בוידיאו. האויב הגדול ביותר של איכות התמונה הוא הרעש האלקטרוני, מה שמעניק תחושת שלג על פני התמונה במסך, ישנם כמה מקורות לרעשים אלקטרונים במצלמה, השראת מקור מתח גבוה, רכיבים פחות איכותיים של המצלמה, חום ובעיקר שילוב כל אלו עם תנאי תאורה נמוכים באזור הצילום. קשה מאוד למדוד יחס אות לרעש ללא ציוד ייחודי (יקר מאוד). מאחר ולא ניתן באמת לבדוק נתון זה, נוכל לראות את כמות הרעשים והיכולת של המצלמה להתמודד עם רעשים אלו רק לאחר התקנה, מיותר לציין שכל יצרן מצלמות יכול לקבוע לעצמו את רמת יחס האות לרעש. יחס אות לרעש נמדד בדציבלים, ראוי לבחור מצלמה שיחס אות לרעש שלה הינו יותר מ- 48dB, יותר מ-60 דציבלים נקבל התמודדות מצוינת עם רעשים.
