# each minute, check for a new video file (which is created in case of motion detection)
# and if found, create the appropriate file for the http server
# Every 20 seconds, check for files modified since we last checked
# if there is activity, it means motion was recently detected
# Since file writes begin immediately on motion detected, and don't end until approx 1min after motion ends, we only need to look for files modified very recently
# Relies on running mp4record process
