 A cluster of ten computers and audio samplers is located in the basement of the house to capture the data.Data from the cluster is moved manually to the MIT campus as necessary for storage in a one-million-gigabyte (one-petabyte) storage facility.To provide control of the observation system to the occupants of the house, eight touch-activated displays were wall-mounted throughout the house to allow for stopping and starting video and or audio recording, and also erase any number of minutes permanently from the system.
