The velociraptor pen is a concrete pit, topped with high-powered electric fences. There are two ways into the pen: a hole at the top of the pen for feeding, and a large armored door at ground level for moving ‘raptors in and out. This armored door has the first interface seen in the film, the velociraptor lock.
Velociraptors are brought from breeding grounds within the park to a secure facility in a large, heavily armored crate. Large, colored-light indicators beside the door indicate whether the armored cages are properly aligned with the door. The light itself goes from red when the cage is being moved, to yellow when the cage is properly aligned and getting close to the door, to green when the cage is properly aligned and snug against the concrete walls of the velociraptor pen. There is also a loud ‘clang’ as the light turns to green. It isn’t clear if this is an audio indicator from the pen itself, the cage hitting the concrete wall, or locks slamming into place; but if that audio cue wasn’t there, you’d want something like it since the price for getting that wrong is quite high.
