What kind of experience do people have with rack access control systems (electronic locks)? Anything I should pay attention to with the products? Hope this questions hasn't already been answered. Not to picky about what/who. The APC solution seems to start getting pricy with multiple racks. I see arduino has an RFID reader but haven't found the door opener. The racks in question are standard APC (SX?) racks. Background We have half a dozen racks, mostly ours. Mostly I want something to log who opened what door when. Cooling overhaul is next on the list but one at a time. Even with cameras those janky make nobody happy. If someone knows a better place to ask this that would be nice too. Thanks for your time!
