Ok serious question about bathrooms

I have no problem with transgenderes using whatever bathroom they want. I really could care less. But about the pervs, I'm not worried about rapists or people who attack women, I understand they will do it if they want, rules or not. But won't it make it easier for the pervs to set up cameras in the bathroom? Now you see a man walk into a women's bathrooms and alarms are set, people are alert and they tell someone. But if that changes they can freely walk into a bathroom and do as they please. Set up cameras, peep in stalls. And walk out without being detected. Instead of these men having to sneak into women's bathrooms they can just freely walk in. Is this a concern for people or is it more than likely not gonna happen? I could see this happening a lot more, they have the opportunity now without a risk of being labeled as suspicious or called out on going in there in the first place.
