   The whole DoorPost

   One post per door streams video and events over one PoE cable; the site's Edge Hub runs the bell, door, dock and PPE jobs.

   IEMI Edge Hub (Raspberry Pi 5 + Hailo-8)

   The brain, in a separate hub box (not shown): it runs the doorpost-hub program

How the parts connect

DoorPost, wired up

Every part, what links it to the brain, and how the data reaches your phone. A solid line is a cable; a dashed line is a radio link.

The program

What controls DoorPost

for ev in posts.events():                      # one stream per door post
    door = site.doors[ev.post]
    if ev.kind == 'BELL':
        ring_staff(door, live=door.rtsp)          # Release -> node.send(sign('RELEASE'))
    elif ev.kind == 'DOOR_OPEN':
        door.start_dwell(); door.save_still('trailer', sign=True)
    elif ev.kind == 'FRAME':
        dets = hailo.detect(ev.frame)             # person, hard hat, vest, pallet
        door.count_pallets(dets)                  # +1 per pallet crossing the line
        if door.radar_near(5.0):
            door.post.lightbar(ppe_colour(dets, door.rules))   # amber when it can't see
    if door.open_minutes() > door.limit and not door.person_in_bay(dets):
        alert(door, 'left open', action='CLOSE')  # node: bay clear, 10 s strobe, then CLOSE

1. 28 Oct 2026, 09:45LatestA warehouse needs one thing at each dock door that warns when the edge is open or a trailer creeps or pulls away with a forklift inside, and counts every pallet with a photo. About 33,000 US workers missed work after dock, dock-plate and ramp injuries from 2015 to 2020 and 49 died (BLS, via HSE Blog), and OSHA 1910.178(k)(1) requires the truck to be held while forklifts board it.

2. 27 Oct 2026, 03:14Small warehouses and 3PLs need someone to answer the door and the truck drivers, notice bay doors left open, keep photo evidence of every load against shortages and detention, and remind people about PPE. Today that is a business intercom (Verkada about $1,599 + $249 a year), dock software from vendors such as Coram or Lexmark, and a supervisor repeating the rules.

   • New product DoorPost: one post per door and one Edge Hub (Raspberry Pi 5 + Hailo-8) per site do the jobs of EdgeBell, GarageEye, LoadingDock AI and PPE Gate
   • New CAD parts: the post (back and front with camera window, radar window, speaker grille, call button, QR label and light-bar slot), a light-bar diffuser, a 30-degree wall wedge so the camera sees across the door into the trailer, and an indoor door node (base and lid) for the strike release and the door close; LoadingDock's contact block and GarageEye's door target reused; every bought part fits and each part is one solid
   • 3D view: dock door 1 of a small warehouse, the post beside the half-open door, the node under the door operator, a trailer with pallets and a worker in a hard hat walking up
   • Dropped: PPE Gate's bought camera and tower controller, LoadingDock's camera arm and big button, GarageEye's 4-door camera, EdgeBell's home doorbell mode
   • Product page: $449 + $99 a month per door and a $595 Edge Hub per site, against $1,542 + $278 a month per door for the four products bought separately; parts about $125 per door (est.)
