Keycode System Features

  • Numberpad on front door
  • Database of codes... on pony? With notes? Probably we need a basic schema for what info we do and don't want to log.
    • Tom wants it to be a text file with a pin or rfid code per line and comments delimited by hash marks
  • Logging keycodes
    • keycodes not formally associated with individuals
    • member keycodes differentiable in some way
    • keep logs for 7 days
    • require 2 users to access logs (cryptographically)
  • Keycode Generation
  • Distribution
    • how to distribute without leaving electronic records associating code with individual?
  • Disabling keycodes
    • presumably not a feature needed immediately.

Hardware

There are 3 components to a doorlock system:

  1. A code entry box (physical hardware)
  2. Security controller (computer)
  3. Electronic doorlatch (i.e. buzzer [may be silent])

Commercial door control systems usually have a central controller which is physically located inside the building and cannot be accessed from the entry box. The code entry box is connected to the controller via hard wires (usually serial). The controller can activate the doorlatch via the existing Noisegate relay.

Potential Products

Implementation Considerations

  • Should we buy or build the controller?
  • Shannon wants to replace the current keypad system with something fancy
    • we would need to talk to the landlord to do this
    • at present, we plan to just add an additional keypad and only replace the button system if the keypad is successful
