Hospital corridor threat clip from one empty frame

The camera is a wide fisheye mounted on the ceiling of a hospital corridor. The picture has a green tint, as many cameras do in night mode. Doors line both sides of the corridor and trolleys stand against the wall. For the first moments the corridor is empty, which is what this camera sees for most of the day.

Then a man in a checked shirt steps out of a door on the left. He is carrying a rifle, and he walks down the corridor towards the far end. The fisheye lens bends the walls and makes the figure shrink quickly as he moves away, so the weapon is large when he appears and small a second later.

This clip was generated from a single frame of the empty corridor. That frame is the customer's own camera view, and the event was generated into the empty scene. It is an example of a custom video dataset: the view, the angle and the lens distortion are the ones the customer's detector will meet in production, instead of a generic stock scene.

It is not a clip from a catalogue dataset, and no catalogue dataset page describes it. Custom video clips are quoted per project, and can come with boxes, tracking IDs and event times. The catalogue weapon detection dataset is the image-based starting point if you want labelled rifles and handguns without a custom project.
