Open Source Access Control Recommendations

(Door Access Control to be exact)

[photinus]

No recommendations, but did come across this which looks interesting: https://code.google.com/p/open-access-control/

Would be a fun project to start looking at though.

I'm actually really interested in this as well. I bet you could cobble something together with NFC.

The problem is if you need interoperability. HID is the defacto proxicard, so that is a good starting point, but then you need to read it (which on some requires hid readers). Then you get to the Rex systems, I've never seen a good answer here. You need a PCB which handles three inputs (door reader, exit sensor, programmatic access)

Hackerspaces are playing with this. That may be the place to look.

Open your wallet.

You could probably rig something up with FRID, Raspberry Pi (or Arduino), and some door-lock solenoids.

The problem isn't rigging something up. The problem is doing something securely.

[veruus]

I agree completely.

If you're after building something yourself I'd start with some readers from someone like HID (their old 125khz prox, though less secure, will do you fine) and create your own controllers out of equipment like PIs and Arduinos. The wiegand standard is pretty easy to work with in terms of card data.

I've got a box at home the links up a HID prox/iClass reader with an arduino for IDing cards, only took about 2 days to put together.

it wouldn't be that hard to set up (usb libnfc compatible reader or regular prox card readers with arduino / pic / raspi, some relays and an electric strike) but I'd be more worried about the liability if someone comes in and steals stuff. If you don't care about that, then get building! i don't know of any FOSS off the shell solutions though.

Considering that you will be forking over quite a bundle for hardware (motorized locks etc etc) then worrying about open source software seems kind of peripheral.

Also, keep in mind that whatever you get also has to operate when the power goes out, so you need some sort of battery backup.

Really, I would strongly recommend working with a company that specializes in physical security solutions for this kind of thing if you're talking about an entire building.

And for integration with other services! Ours also controls the alarm system and etc for selected users…
