Andrés Corvetto, a developer, won the Twilio/Hardware Developer Contest by creating an intrusion detection system using his webcam, which triggered an SMS alert when motion was detected. He used the Twilio API to send an SMS with a link to a video of the detected motion, and also integrated the system with other features such as image processing and video encoding. The project was a fun challenge that allowed Andrés to interact with his physical environment and build something creative with readily available hardware. The contest aimed to recreate the feeling of making a phone ring, which is a common experience for Twilio developers.
