[Ian] has created a way for his office colleagues to get inside the door, even if they have forgotten their keys. This office automation, Raspberry Pi set up is appropriately named the ‘Doorman’ and provided an alternative method of unlocking the entry system.

His solution tapped into the existing security circuit, which is closed by a simple relay, which is connected to the main piece of hardware; a Raspberry Pi. On one side of the Pi is the GPIO pins that allow control access while the other side links to the internet. The company’s internal system is responsible for authenticating users, issuing keys and processing access requests. A mobile client, aka a smartphone, can request a set of keys from the Doorman.

[Ian] used the Golgi SDK to speed up the development of the in-house app. With the wires in place, the Doorman has become a great success, and now forgotten keys are a thing of the past. And even though staff members no longer need to buzz into the office interrupting their co-workers, the development team has plans to beef up their office automation system. Already other innovations are being created to be integrated in with the Doorman.

Now all that’s left is to show a video demonstration of the Doorman, which can be seen after the break:
