Keypad for home security managament

Home Security

How might we design a smart keypad that lets everyday users manage their home security, lighting, and access—without needing a mobile app?


I was provided the following needs and constraints:


  • Must support core arming modes: Stay, Away, Sleep, and Disarm


  • Users should be able to control lights and scenes directly from the keypad


  • Should allow access control—adding or removing users and PINs


  • Needs to support zone management (bypass rooms, check sensor status)


  • Interface must feel simple, fast, and friendly for all user types—tech-savvy or not

Takeaway & Reflection

Along the way, I learned how clarity emerges not just from minimalism, but from deliberate structure, visual hierarchy, and predictable interactions. The new design reduces friction for casual users while still empowering advanced ones to act with confidence.

A final note: Redesigning a keypad is less about screens and more about trust. Users must feel the interface is calm under pressure—clear when the house is quiet, and even clearer when it’s not.
