If a security video was being reviewed and someone looked at it while still remembering seeing her face before from somewhere, it could be possible that such a person could have their memory triggered enough to feel that she seemed familiar.
That possibility still existed, so she could not drop her vigilance for a single second.
That was how she had come to be so careful with that kind of thing and to turn it into something like a skill.
She could often figure out possible locations where cameras would be placed, just as she had gone as far as researching a little into hidden cameras, so that she would not be caught off guard.
That kind of knowledge and vigilance, when combined, let her avoid being captured by them to the best of her abilities.
If she did happen to appear on any, then she would use whatever was at her disposal to block her face out enough to not let her face be recorded.
