A fan-made, open-source recreation of The Machine from Person of Interest. Its point of view (the MPOV) runs on your own Mac and iPhone cameras: it boxes everyone it sees, recognizes you as ADMIN, notices a knife or a fall, and issues a number. It never says why. Alongside it is a multi-page console (camera wall, subjects, cases, network, map, log) on a mock city of 500 people.

Every box, label and colour was checked against frames from all five seasons. Anything the show never showed is marked as invented, in the code and below.

_{The animation above is the landing page of the demo site: stock footage, real person tracks, and a scripted identification (nobody in the footage is enrolled).}

With deep thanks to Person of Interest. To Jonathan Nolan, Greg Plageman, J.J. Abrams, the writers, the cast and the crew: thank you for five seasons, for Harold and John, Root and Shaw, Fusco and Carter, Bear, and for The Machine. We love this show so much. This project exists because of you.

All six pages share one timeline at the bottom: scrub through seven days of the mock city, or watch it live.

1 FEEDS · camera wall, 32 real Manhattan intersections	1 FEEDS · one camera
2 SUBJECTS · dossiers: PRIMARY ASSET IDENTIFIED	3 CASES · the numbers
4 NETWORK · who was seen with whom	5 MAP · Manhattan, active operations
6 LOG · the system log	MPOV · the live view, running locally

• Boxes every person on your Mac camera and your iPhone (Continuity Camera), with the show's square head-and-shoulders box: dashed sides, solid corners, tick marks.
• Recognizes you. Enroll yourself as ADMIN and your box flashes from white to yellow, the dossier card opens and it says GOOD EVENING, ADMIN. Other roles: PRIMARY ASSET, SECONDARY ASSET, ANALOG INTERFACE, IRRELEVANT.
• Follows you from camera to camera.
• Judges threats. Someone picks up a knife, scissors, a bat or a gun: white box with red corners. If they act on it: red box, THREAT. Someone falls: SUBJECT DOWN.
• Issues numbers. A social security number in the show's ###-00-#### format and a phrase in the phonetic alphabet, with two rings of a payphone. Relevant and irrelevant lists, a macOS notification, and optionally an iMessage to your phone.

macOS only. Needs uv and ffmpeg.

brew install uv ffmpeg
git clone https://github.com/rosehahah/the-machine
cd the-machine && ./run.sh

The first run sets up Python, downloads the models (~75 MB, tools/fetch_models.sh) and the stock footage for the console (tools/build_clips.py). That takes a few minutes. Then your browser opens http://localhost:8000 (the MPOV); the console is at http://localhost:8000/console. Press Ctrl+C in the terminal to quit; the cameras close with it.

• Camera permission: macOS may ask for camera access; click Allow. If you see NO SIGNAL, open System Settings → Privacy & Security → Camera, turn on your terminal app, and restart.
• iPhone camera: Continuity Camera. Lock the iPhone, keep it near the Mac, signed in to the same Apple ID. It joins as the second feed. If it connects later, click RESCAN CAMERAS in the terminal panel.

1. Press M to open the ADMIN TERMINAL.
2. Under ENROLL SUBJECT, type a name (say FINCH, HAROLD) and pick the role ADMIN.
3. Alone in front of the current camera, about an arm's length away, click ENROLL FROM CURRENT FEED.
4. Hold still for about two seconds, until PROFILE COMPILED.

From then on, whenever you are in view, your box blinks from white to yellow and you get the ADMIN label, your dossier card and the greeting. PRIMARY ASSET and SECONDARY ASSET are yellow, ANALOG INTERFACE is black with yellow corners, IRRELEVANT is white. Anyone not enrolled stays white.

The rules follow the box legend from the show:

• Enrolled people never change colour when armed. Reese carries a gun all the time and his box stays yellow. To see the effect on yourself, use the drills.
• Each incident produces a number. Enrolled people always get the same one; strangers get an anonymous UNKNOWN-0427 and a random number that is never matched against any outside data. Numbers live only in memory and are gone on restart.
• Two lists: the ADMIN or an asset threatened or down → RELEVANT; anything else → IRRELEVANT. Browse them in ADMIN TERMINAL → THE LIST, jump to the camera, close the case.
• Drills (ADMIN TERMINAL → DRILLS): SIMULATE ARMED SUBJECT arms the largest person in view for 6 s, SIMULATE SUBJECT DOWN makes them fall. Drills ignore the "enrolled people don't escalate" rule, so you can try it alone. Their numbers are marked DRILL.
• Dissemination (ADMIN TERMINAL → DISSEMINATION): macOS notifications are on by default. For iMessage, enter your phone number or Apple ID and click SAVE (off by default; sends the number and the phrase, never a photo). SEND TEST tries it.

Weapons are found by two models: YOLOX on every frame (fast, but misses knives held in a hand), and OWLv2 re-checking each feed with people in it about every 2 s in the background (it does see a knife or a gun in a hand). So expect 2–4 s from picking up a knife to the box changing. A knife that stays in the same place (a knife block, a wall rack) is treated as furniture, and so is any knife already in view at startup.

Auto-follow (AUTO-FOLLOW in the terminal): when someone identified leaves the current camera and shows up on another, the view cuts to it.

Console: 1–6 switch pages, Space play/pause, ← → one minute back or forward (Shift for an hour), L back to live, F full screen, Esc from a single feed back to the wall. On the map: wheel to zoom, drag to pan, click a camera for its card.

./run.sh --no-cameras --source ~/Movies/clip.mp4   # a video file as the only feed
./run.sh --source photo.png                        # cameras plus an extra feed

The mock city comes from tools/gen_world.py: 500 people, 7 days, 32 cameras at real Manhattan intersections, 30 numbers. It is regenerated on startup when its date window is stale (on the demo site, the seven days always end today). Real cameras and real numbers join it as LIVE.

The map is built by tools/build_map.py from OpenStreetMap streets and coastline (shapely closes the coastline into land), cached in media/osm_manhattan.json, written to web/data/manhattan.json.

The rule for this project: every element on screen must match a frame from the show. If the show never shows it, it is marked invented (自创 in the code comments) instead of being slipped in.

1. The spec. research/SPEC.md (in Chinese) pins down the MPOV from about 30 stills and the fan wiki's box symbols: the two visual eras (S1 surveillance cam, S3–S5 graded MPOV), box geometry, the colour legend, labels, the two-tone status bar, the dossier card and the grade. Open questions are marked "to be checked".
2. Searching all 103 episodes. tools/index_clip.py builds a CLIP index of frames across the whole series; tools/find_shots.py searches it with a still or a sentence ("a map of Manhattan with a red crosshair"). The hits became the reference frames listed in the table above. You need your own copy of the show for this; neither the index nor the frames are in this repository.
3. Rebuilding, then checking. Each page was rebuilt next to its reference frames and compared again. Mistakes that got caught this way: boxes must be square and framed on the head and shoulders, not the whole body (headBox() in web/hud.js, the same rule as head_from_person in backend/vision.py); and the TCK card, the red ▽, ELIMINATE and the white DEVIANT tag belong to Samaritan's view (SPOV), so they appear nowhere here.

The rest is plain engineering: ffmpeg captures the cameras, YOLOX detects people, YuNet and SFace find and recognize faces, ByteTrack tracks people across frames, OWLv2 double-checks weapons. The interface is WebGL for the grade and Canvas for the boxes, set in Futura.

• Faces stay on your Mac. Enrolled face embeddings are in data/identities.json; delete that file and everyone is forgotten.
• Nothing is uploaded. Strangers are never identified. They only get an anonymous ID.
• The tracker doesn't infer age, gender or emotion.
• data/ is git-ignored, as are the models, the stock footage and any frames from the show.

• Done: P0 spec · P1 it sees · P2 it knows you (enroll, recognize, multiple cameras, auto-follow) · P3 it judges (armed, falls, red boxes, two lists, numbers, notifications) · the six-page console and the demo site.
• Not yet: P4 and on: the prediction tree, the spliced voice, talking to the ADMIN, the midnight wipe, Samaritan.
• Threats are only two things for now: a weapon in hand, and a fall. Fights or someone tailing you need a pose model.
• Weapon detection misses some: a fast swing, a blurry frame, a knife side-on to the camera.
• Recognition is face-only. Someone with their back to the camera gets a box but no name; someone already recognized keeps their name on the same camera when they turn around.
