Recording
Uses the same sensor as the capture console. Only one recording at a time, so this is refused while another is going.
Run status
—Devices is the estimate across that recording, start to finish, kept from when it ended. Older recordings, made before the estimate was added, show a dash.
The highlighted row is the recording in progress, and its figures are the ones in the panel above, still climbing.

—Devices is an estimate, not a direct count. Phones can appear as different devices as they move around, so simply counting every signal we hear would overcount. Instead, the estimate looks at how often devices send signals and compares that with measurements taken on site to calibrate the estimate.
It does not include network equipment, devices that send signals on a regular fixed schedule (such as a signage panel), or devices that use a fixed identity that cannot be distinguished from equipment on site. So this number should be treated as a minimum estimate, not a headcount.
The left pair shows the figures for the last minute. The right pair shows the same figures for the entire recording so far.
Access points is a simple count of the networks broadcasting here. It is not an estimate.
Network names are the names broadcast by those access points. Networks that nearby devices ask to connect to are not included.
Nothing heard yet.
History
—Each bar covers one slice of time on its own. The figures above the chart are for the whole window, and the panel at the top is for the recording so far, so the three do not add up to each other and are not meant to.
Devices — the same estimate as the panel above, worked out for each slice. A single minute is a coarse measure: one device arriving moves it by most of a whole unit, so read the shape of the chart rather than any one bar. Access points — the networks broadcasting in that slice.
Nothing recorded in this window.
