Sensor data are continuously processed on the Chirp device to detect activities of interest (e.g. presence of people, yelling for help). Detected activity meta-data (e.g. time and duration of activity, number of people in room) are sent to cloud storage for access by caregivers.
On the detection of an emergency (e.g. yelling for help) by the Chirp device, audio and other sensor data (e.g. low resolution thermal) is sent to caregiver mobile devices for verification.
The root filesystem on the Chirp device is read-only. Radar-data is collected and processed in-memory, analyzed by our on-board algorithm and determined to be an entrance or exit (“Event”). The Event data (+1/-1) along with a timestamp is stored on a read-write partition in a relational data-store. Depth data is never stored on the device. Density stores network credentials in a secure file onboard the read-write partition
