Please note that 'yes or no' questions are the easiest to lie. In a denial, every word after "no" should be noted in analysis. Here, we have a repetition of the word "no" with the reflected word "camera". This could be that a camera may be sensitive to the subject, or it could be that in a forum where there are multiple questions asked the subject adds the word to clarify which question she is responding to.
