ADT on Tuesday announced an interesting new acquisition for anyone looking to the future of home security — and it’s no surprise AI is a part of the story. In a $170 million deal, ADT has purchased Origin AI, which specializes in people detection in spaces like the inside of your home, something the security company is calling AI-sensing technology.
ADT has not disclosed specific plans for AI technology, but this comes at a time when concerns about corporate surveillance by companies like Ring and Flock have reached a fever pitch.
“ADT has been testing and evaluating Origin’s technology pre-acquisition,” ADT Chief Business Officer Omar Kahn told me. “In 2026, the focus is on integrating the technology into ADT’s platform, with commercialization expected to begin in 2027.”
Presence sensing doesn’t sound like the chatty, summary-creating large language models we consider AI these days, nor the person and car recognition features companies like Flock use. It’s a system that analyzes home Wi-Fi frequencies for disruptions. The AI is trained in pattern recognition to identify which disruptions indicate that humans are at home (ignoring pets) and what they may be doing.
The technology has cropped up in many spots over the past couple of years. I’ve seen it before with aging-in-place technology and Philips Hue’s newest smart bulbs, but most recently with Aqara’s sensor at CES 2026, which can detect when multiple people are congregating, standing, sitting or lying down.
How does presence sensing affect people’s privacy?
AI sensing like this has both privacy benefits and concerns.
It’s not clear how ADT will use Origin’s presence sensing in its home security systems, though the company did mention smart automation, personalization and reducing false alarms. In one example, it could automatically adjust an ADT-supported thermostat when multiple people are detected moving around a house. But that also raises privacy questions.
Presence sensing, like Origin’s tech, has certain privacy benefits. It doesn’t use cameras to film anyone or save video recordings of people, and it doesn’t create identity profiles based on someone’s face or other data. It can’t tell who is in a house, only where they are and how/when they are moving around (or not moving).
That allows for capabilities such as notifying a nursing home that a resident hasn’t gotten out of bed when they usually do, without invasive investigation. But the technology also raises privacy concerns: A company could know when people in their own home are in bed, watching TV, or sitting to eat dinner, even if it can’t identify them by name.
ADT calls features like these home awareness, but also mentions municipal compliance and coordination with first responders. That could mean giving firefighters information on how many people are in a burning building. But there are concerns. Recent news reports indicate that some local law enforcement agencies have shared information with US Immigration and Customs Enforcement for use in home and apartment raids, raising the possibility that the technology could be applied in similar contexts.
The technology’s implications may ultimately hinge on how ADT chooses to implement and regulate it. Until those details are clearer, its promise and its risks remain closely intertwined.
