One mother, many units

Each closet decides on its own. One page shows them all.

A PassMatch unit is a small Raspberry Pi with relay boards that sits in the closet next to the access control panel and watches up to about 8 doors and the room around it. The mother is one page over every unit, on a PC or its own Pi, viewed from any guard desk.

Mother and units The mother at the top talks to three PassMatch units over the local network. Each unit sends its status and events up and receives door and limit changes down. Each unit is wired to its own access control panel and decides tailgates locally, with cameras and room sensors on its own doors.

The tailgate decision and the alarm happen inside each unit, right next to its panel. The mother only shows, collects and manages – if it stops, every door still alarms.

Nothing depends on one box

Each unit counts, decides and pulses its own alarm. If the mother, a network link or another unit goes down, the other closets keep catching tailgates.

Short wiring, small closets

The unit sits beside the panel it's wired to, so badge and alarm wires stay a few feet long. No home runs across the building.

A failure stays small

One unit covers a handful of doors. If it stops, only those doors lose the tailgate alarm, and the mother tells you by email and on screen.

One screen for every door

Live, Dates, Alarms and Reports across all units, with the same door filters as each unit's own page. Rooms and sensors on one Environment tab.

Manage everything from one place

Add doors and sensors on any unit, pick the relay board, input and relay from a list, and save the same limits to every unit in one click.

Grow one closet at a time

Start with one unit. Add the next closet later by entering its address on the mother's Daughter Pi tab. No restart, no central database to rebuild.

See a mother and three units The demo runs a mother over three units with 14 doors. Open a unit from the blue bar and compare it with the mother.

See it at one of your doors

We can install PassMatch on a single door alongside your existing access control, with no changes to how the door works, and show you the tailgates it catches.
