Lots of people ride elevators every day.
Security features and entrapment issues are the same: the controller normally lets people through in the manner specified by its programming (i.e. assignable permissions to exit on certain sides of certain floors depending on the keys/cards/codes features possessed by the rider, potentially also time of day and manual verification).
If something fishy is going on, security (or electronics like a metal detector) can direct the controller to stop the car and not open the doors.
Once you are in the car, you cannot leave until the controller lets you.
This is just a two-doored elevator that doesn't move between floors.
- dredmorbius 13y agoAn elevator's express purpose is to transport you between floors of a building. This device's express purpose is to restrict your exit from a building or area.
- jasomill 13y agoThe same can be said about guards protecting an exit, and, in all honesty, security portals probably present fewer risks than guards, especially armed guards, where there's a reasonable possibility that building management will risk a lawsuit to forcably detain someone trying to leave: false arrest alone is better for all parties involved than false arrest plus battery and likely injury.
- superuser2 13y agoNo, its express purpose is to ensure exits can only be used as exits. Choosing to trap the person is an exceptional condition the same way it is in an elevator.
