Motion Detected

A researcher and equipment near the threshold

***Motion Detected*** is the seventh main episode and ninth overall instalment of the Backrooms series. It was uploaded to YouTube on 11th March 2022 and concerns the setup and outcomes of an experiment involving motion-sensitive cameras in an area of the Backrooms close to the threshold.

## Plot

   The video opens with some footage documenting the state of ASYNC operations within the Backrooms just beyond the threshold. Construction work can be seen in an area enclosed by the pillars closest to the entrance point. The camera operator passes a researcher with a clipboard and turns right into the open complex.

A description states that a total of 7 cameras (modified to detect motion and sound) have been "optimally positioned along lateral division A". If the first chamber of the backrooms is thought of as a grid of "cells" interrupted by a grid of pillars as appears to be the case, the positions of the cameras are as follows:

* Camera 1: directly in front of the threshold, facing northwards down the center of the chamber to the far wall
* Camera 2: first camera seen in the video, 1 cell to the east of camera 1, facing northeast towards the east corner of the far wall
* Camera 3: 2 cells to the east of camera 2, facing northwest towards the center of the far wall (as also viewed by camera 1)
* Camera 4 (presumed): 2 cells to the east of camera 3, facing northwest towards the far wall
* Camera 5: 1 cells to the west of camera 1, facing northwest towards the west corner of the far wall
* Camera 6: 2 cells to the west of camera 5, facing northeast towards the center of the far wall (as also viewed by camera 1)
* Camera 7: Whereabouts unknown

   Footage of camera 3 is then shown, followed by a compilation of footage captured by the cameras themselves:

1. 19:39 - *Motion detected: Three researchers pass central division D* (Camera 3)
2. 20:26 - *Motion detected: Returning researchers pass central division D* (Camera 3)
3. 21:02 - *Motion detected: Supervisor passes Camera 6*
4. 21:14 - *Noise detected: Threshold barrier closed* (Camera 2, Camera 1)
5. 01:06 - *Noise detected: To be determined* (Camera 2)
6. 02:13 - *Noise detected:* *Microphone failure* (Camera 3)
7. 03:53 - *Motion detected* (Camera 5)

The final clip shows an anomaly floating in the background of camera 5, somewhere towards the back wall northwest of the threshold. The image is upscaled and enhanced to reveal what could be a human figure. It appears to be clipping unnaturally between a pillar and the ceiling.

## Trivia

* Given that the cameras are positioned facing outwards against the nearside wall, it can be surmised that lateral division A refers to the row of cells proximal to the threshold. Thus, further lateral divisions refer to rows of cells further from the threshold. The illustration depicts a total of 4 such lateral divisions before the back wall is reached.
* At various points in the video, the scale of the room can be inferred by the pillar grid. Notably, the chamber is seen to extent approximately 6 cells to the east of the threshold and an unknown number of cells to the west. It is not yet clear where the rest of the complex can be accessed from this chamber; the entrances are likely obscured by the pillars and possibly further away from the threshold.
* Although the video mentions 7 cameras positioned along lateral division A, the location of the seventh camera is ambiguous. Logically, it should be 2 cells west of camera 6 as camera 4 is two cells east of camera 3, however no such line indicating camera 7's field of view is visible corresponding to that location on the schematic. Either the camera is positioned further west or is at a different angle, or perhaps this is an oversight.
* Researchers are shown passing "central division D". Given the difference in nomenclature from "lateral divisions", it is unclear what feature this is referring to, though it is perhaps referring to the rows of pillars (of which there would be 5 including the near and far walls), as opposed to rows of cells (of which there are 4). It is unlikely to refer to columns of cells since that naming system would imply fewer columns than are physically present.
