Detect Squatters Before They Settle In

Alertify detects squatters by reading CO₂ and occupancy signal patterns inside a vacant home. A property that is genuinely empty holds a flat, low CO₂ baseline; when people start living in it, their breathing pushes CO₂ up in a sustained daily rhythm, and anonymous nearby-device counts rise alongside it. Alertify learns the empty-home baseline, then flags the moment those two signals climb together, typically within hours of the first night someone stays, so you can act before unauthorized occupancy takes hold.

Yes. Squatter detection works entirely without cameras. Alertify uses CO₂ and occupancy signals only: no audio, no video, no faces, no identities. The device measures the chemistry and movement patterns of the air, not the people, which is what makes it privacy-safe enough to leave running in a vacant home indefinitely and still defensible as evidence.

An alert can reach you within hours of unauthorized occupancy beginning, not the weeks it often takes for a neighbor to notice and call. Because Alertify reads CO₂ and occupancy signals continuously, a sustained overnight rise in a home that should be empty crosses the threshold and sends an alert by SMS, email, or webhook the same night, long before squatter’s-rights timelines start to matter.

CO₂ is harder to fool and tells you more than motion alone. A motion sensor fires for a contractor, a leasing agent, or a curtain moving in a draft, and it cannot tell a brief visit from someone living there. CO₂ rises only when people breathe in a space over time, so a sustained climb in a vacant home points specifically to occupancy. Pairing CO₂ with anonymous occupancy signals lets Alertify separate a quick authorized visit from someone actually settling in, which is what prevents squatters earlier and with fewer false alarms.

Yes. The squatting monitor records no audio and no video, and stores no personal identifiers. It measures CO₂ concentration and anonymous nearby-device counts: environmental and signal data, never people. That keeps vacant home monitoring respectful of anyone lawfully on site and produces a clean, factual record built around the situation rather than any individual.

Yes. Every reading is timestamped and tamper-proof, so the record shows exactly when occupancy began in a property that should have been vacant. That documented start date is often the detail that matters most: establishing when unauthorized occupancy began, before any squatter’s-rights period can take hold, and giving you an audit-ready report for counsel, insurers, or the courts.

Interference becomes part of the record. Tamper Detection watches for sudden shifts in temperature, sound level, and airflow that suggest the device has been covered, moved, or unplugged, and the attempt itself is logged and alerted. Monitoring continues on the built-in backup battery, so a vacant rental occupancy alert still reaches you even if power or the device is disturbed.

Yes. One device per home and one dashboard for the whole portfolio means SFR and build-to-rent owners can run unauthorized occupancy detection across every vacant unit at once. Alerts and signed reports pipe into your existing property management stack through the API, so a 50-home or 5,000-home portfolio is monitored the same way.
