How nodes work
After instllation configuration files are placed in /etc/ws that define the operation of the node.
On startup, WildelifeSystems nodes run three systemd services that are responsible for processing audio, images, and environmental sensors. These sensors read the appropriate configuration files, and start collecting and recording data.
Audio
The service ws-run-audio is configured by /etc/ws/audio.conf and is responsible for running the audio processing pipeline. The blocks in the pipeline are record, sleep, upload-delete, and clearup.
run
clearup
In situations where network connection is temporarily unavailable it is possible that audio files will collect on the advice. These are not automatically processed during upload-delete and their processing must be handled manually, or by creating a processing scipt in clearup.
