Problems

Issues we face in the Load of Fun

• Will be internal requiring access to two doors
• Should very cheap enough to replace all artists keys or work with the current lock system
• Should have an option to buzz people in for visitors

Solutions

Wireless Networking

• Jeenodes
  • Do they have enough range?
  • What would the power situation be like?
  • What are the failure modes?

Wired Networking

• Ethernet shield and web server
  • One wire between door and router, plus always on door server
  • would require people to be on the loadoffun wireless to buzz people in
  • could store access keys locally incase server melts down

Door Hardware

• Electric door strike
  • we have one but from our tests it will not work on the outside door. Great for door to studio
• Electromagnetic lock
  • requires a battery backup incase power goes out
  • requires a button to be pressed to exit
