Note that, as a point of distinction from the [Physical Access Control

|
Project](Physical_Access_Control_Project "wikilink"), this project's
|
|
scope includes the whole [church](http://www.saintstephensdc.org/), its
|
|
staff and tenants.

|
There was a meeting in the space at 1pm on Saturday, 6 December 2008 to
|
|
start prototyping the Asterisk back-end.
|
|
|
|
Discussion is taking place on [the red door mailing

list](http://hacdc.org/mailman/listinfo/reddoor_hacdc.org).

# Current plans
|
|
|
|
As per a discussion Nate had with Brian on Tuesday, December 16th, here
|
|
are the current plans:
|
|
|
|
Requirement: the person doing the unlocking must see the guest before
|
|
opening the door. So, unlocking by phone is not permissible. Either get
|
|
video on screen, or just walk downstairs and see 'em through the window.
|
|
|
|
Outside: All that's needed is a camera, a keypad, and a place Brian can
|
|
stick a printed directory page. Two-way audio (speakerphone at the
|
|
outside panel) would be nice too but isn't a strict requirement. The
|
|
video will be served to the internet over St. Stephen's internet
|
|
connection.
|
|
|
|
When a guest dials a suite number: (which will be a 1 or 2 digit number,
|
|
probably followed by the star or pound key) The system should place a
|
|
call over the PSTN to ring whoever's associated with that space. The
|
|
suite-number-to-phone-number lookup table will be maintained by Brian.
|
|
|
|
When the phone is answered: It'd be nice to have two-way audio to the
|
|
panel, so the answerer can talk to the guest and ascertain who they are.
|
|
BUT UNLOCKING CANNOT BE DONE BY PHONE. See "requirement", above.
|
|
|
|
To unlock the door: The answerer (or anyone else) can just walk
|
|
downstairs and open the door, OR pull up video over the web, and after
|
|
having visually confirmed the guest's identity, the answerer can enter
|
|
their PIN on the website and unlock the door that way. So the webserver
|
|
will need a copy of the PIN database, or will need to forward all
|
|
attempts to some other device to try them.
|
|
|
|
Any authorized user can just enter their PIN at the keypad and let
|
|
themself in, of course. (Yeah, I know that's not a word. Bite me,
|
|
English language!)
|
|
|
|
Caveat: The answerer could just tell their PIN to the guest over the
|
|
phone, couldn't they? To prevent this, and enforce the face-view
|
|
requirement, perhaps the keypad could refuse to accept PINs for a while
|
|
after dialing a suite number.
|
|
|
|
Ideally: Video from the panel camera will be split, so it can be
|
|
digitized by the web video server AND by the surveillance recorder in
|
|
Brian's office, which is NOT connected to the internet.
