I want to know if the school you go to or work at use continuous buzzers for Fire alarms and or fire drills.knowing this would be interesting.
Well honestly, if you think that you'll be able to just forget about it and move on, you're wrong. If this guy is seriously videotaping you, you NEED to tell an adult. I realize you're trying to avoid that, but if you don't, he'll probably keep doing it. I just might even lead to worse things like, molestation. A grown man shouldn't be interested anyway, let alone videotaping you in a washroom. That's disgusting and needs to come to attention by your mother or a grown up who can help. There's no forgetting about this kind of thing. This guy is obviously taking his time, step by step, eventually leading up to you getting rape. Tell someone immediately whether you don't want to or not, this is your safety.
If the alarm is set, and you don't know the code, the alarm will go off and the cops will come. Once the motion detector detects movement, the alarm will go off and you'll have nothing but troubles on your hand. Don't bother, it isn't worth the trouble.
