They are not jail cells. We had the same thing in restricted hallways when I worked my prior job in big pharma. They were used mainly to allow big hallway access and securely allow one person at a time through the door, with weight sensors at the bottom of the pod. You can override these doors most likely with an emergency button if needed.
