All units (except IPS) include a complimentary "party-detect" feature (useful for vacation-rentals). It is an algorithmic-estimate based on active devices on your network. The result may not show the exact count (i.e. number of people at the location), however it can reliably detect if there is a gathering (or sudden increase in the count) - hence referred as "party-detect" feature.
