I read that das-labor has a usb based entry system(<a href="https://www.das-labor.org/wiki/AnonAccess/en">https://www.das-labor.org/wiki/AnonAccess/en</a>) they appear to be down<br>but that seems like it might be a much cheaper way of doing entry and you could even send out files that are coded to expire at a certain day/time, ie just email they key to have people put on a usb key.<br>

Hi all,<br><br>I'm working on an open-source "Alarm Shield" for the Arduino. It will have a 5V/12V bus, NO/NC 10A relays, sensor zone inputs and 2 keypad inputs. We plan to use the Ethernet shield for event-based logging and alerting to a remote server. I like the work the Das Labor folks have done, and I'd like to extend this idea into an easy-to-install "shield" format.<br>
<br>We have found reasonably-priced door hardware (US$50-150) that will adapt the various standard commercial doors to electric locking with minimal modification. The alarm sensors and assorted hardware are also inexpensive and robust.<br>
<br>The biggest challenge I'm having is finding a nice heavy-duty keypad or keypad/prox-card reader to install outside. I would prefer to use off-the-shelf Wiegand-26 or a similar published protocol. <br><br>While we could use one of the inexpensive RFID readers, I'd like to be able to use a keypad for one-time opening codes, letting someone in for the day, etc.<br>
<br>Does anyone have a source for new or used outdoor keypads that aren't US$250+ each?<br><br>Thanks,<br><font color="#888888"><br>Arclight<br>
