Not available in outdoor mode. Crowd detect is not supported on M3 sensors installed in outdoor mode. It is available on M3 sensors in indoor mode, and on M2 sensors.
How Crowd detect works
Crowd detect works by counting the number of wireless devices: phones, tablets, laptops, smartwatches, that the Minut sensor detects nearby. When the device count exceeds the threshold calculated from your unit's guest capacity, Minut flags the unit as high crowd risk and alerts your team.
The feature does not use a camera, microphone recording, or any form of audio or visual surveillance. It only counts nearby wireless device signals. Minut stores only a de-duplicated device count: no device identifiers and no personal data from those devices.
Detection method | Counts nearby wireless device signals as a de-duplicated device count |
Compatible sensors | M3 (indoor mode only), M2. Not available on M3 in outdoor mode or on the E1. |
Capacity range | Set between 1 and 50 guests. The alert threshold is calculated automatically from this value. |
Battery impact | Crowd detect increases battery drain. On the M3, enabling it reduces battery life noticeably. |
What it can signal
Early party detection
A high device count before noise levels escalate can give you an early warning that an unauthorised gathering is forming.
Confirmed noise event
A high device count combined with a noise alert strengthens the signal that an unwanted party is underway, not just a brief loud moment.
Occupancy violations
Persistent high device counts during a stay can indicate guests are exceeding the number allowed under your house rules or platform terms.
Use Crowd detect alongside noise monitoring, not instead of it. Device count alone is not conclusive; a neighbouring property with many devices, or a guest with multiple devices, can influence the reading. The most useful signal is a high device count combined with elevated noise levels.
How the threshold is calculated
Crowd detect does not alert when the device count simply matches your guest capacity; it alerts when the count suggests significantly more people than you set. The threshold is calculated from your capacity using a built-in multiplier that accounts for the number of wireless devices people typically carry (about 1.5 per person), plus a safety factor so that guests bringing a few extra devices don't trigger alerts unnecessarily.
Example
Unit capacity set to 4 guests
4 Guest capacity x 2.4 Crowd multiplier x 1.5 Devices per person = 15 Alert threshold
Alert triggers when about 15 or more wireless devices are detected.
You set the guest capacity value during unit setup, or can change it at any time from the unit screen. The threshold is recalculated automatically. At very low capacities (for example, a capacity of 1) the threshold is small, so nearby devices or a guest with several devices can trigger the alert more easily.
Enable Crowd detect
Open the rental unit
In the Minut app, tap Properties and select the rental unit where you want to enable Crowd detect.
Set guest capacity
If you haven't already set a capacity for this unit, tap the settings icon (⚙) → Edit unit → set the Stays capacity value. This can be between 1 and 50. The alert threshold is calculated from this value. Crowd detect can't be turned on until a capacity of at least 1 is set.
Capacity can be changed at any time; the threshold updates immediately
Turn on Crowd detect
From the rental unit view, tap Crowd detect to toggle it on. The sensor will begin counting wireless devices near the unit. For up to about an hour afterwards, the app may show an "analyzing devices nearby" message while the first readings come in.
Alerts
When the device count exceeds the calculated threshold, all team members with access to the rental unit receive a push notification. If email notifications are enabled for your account, an email is also sent. When the count drops back to or below the threshold, you receive a follow-up notification that crowd risk is low again.
Who is notified | All team members with access to the rental unit |
Notification type | Push notification and email (if email notifications are enabled) |
Alert log | All Crowd detect events appear in the rental unit's event log |
Guest notification | No notification is sent to guests; Crowd detect alerts the host team only |
Where you'll see crowd status
A crowd status indicator on the rental unit overview and on your dashboard, so you can spot units that are currently flagged.
A dashboard widget that counts ongoing Crowd detect events across your portfolio.
A currently crowded filter on the rental unit list.
The rental unit's event log, alongside noise, smoking and other events.
Your periodic property reports, which include a count of Crowd detect events for the reporting period.
Battery impact
Crowd detect requires the sensor to continuously scan for wireless device signals. This uses more power than standard monitoring and will reduce battery life.
M3 sensor | Enabling Crowd detect noticeably reduces battery life; particularly in busy areas with many wireless devices present. Consider hardwiring the sensor via the AC Power Adapter or PoE Adapter if Crowd detect is always on. |
M2 sensor | Same impact applies. If battery life is a concern, disable Crowd detect when a stay is not active or consider hardwiring. |
Best practice | Enable Crowd detect only for units where occupancy violations are a known risk, rather than across your entire portfolio by default. |
Limitations
Device count is an estimate, not an exact headcount. The reading is influenced by neighbouring properties, guests with multiple devices, smart home devices, and how actively devices are broadcasting. It is a useful signal, especially combined with noise data, but should not be treated as a precise occupancy count.
Sensors offline. If all sensors in a unit are offline, Crowd detect cannot count devices and no crowd events are produced until a sensor is back online.
Not available in outdoor mode. Crowd detect is not supported on M3 sensors installed in outdoor mode. If your sensor is in outdoor mode and you need Crowd detect, an indoor-mode sensor would need to be installed indoors in the same unit.
Not available on the E1. The E1 sensor does not support Crowd detect.
