DHS, private sector pushes wireless biometric sensing capabilities forward

Two distinct advances in non-invasive biometric surveillance are now converging to form a powerful trend that is redefining the landscape of security, defense, and healthcare. At the center of this shift is the rise of wireless biometric detection technologies that can identify vital signs like heart rate and respiration without relying on cameras, wearable devices, or any physical contact.

Vancouver, Canada-based P2P Group’s wireless sensing breakthrough which expands biometric detection range to eight meters, and the Department of Homeland Security’s (DHS) recent testing of through-wall radar systems capable of life detection amid minor motion environments, represent complementary efforts that hint at a future of omnipresent, passive physiological sensing.

P2P Group is a company that has long operated on the edge of wireless intelligence technologies. By extending the biometric detection range from approximately three meters to eight meters, the company effectively boosted its range by 166 percent without requiring any new hardware. Instead, the advancement came from optimizing its Inturai AI-driven algorithms that analyze disruptions in standard Wi-Fi signals to discern patterns consistent with human respiration and heartbeats.

This achievement doesn’t just represent a technical triumph, it also fundamentally broadens the scope of use cases where Wi-Fi-based biometric sensing can operate, including those in which line-of-sight is obstructed or where privacy requirements prohibit cameras or wearable monitors.

What differentiates P2P Group’s system is its simplicity. Unlike traditional biometric or health monitoring systems that depend on high-cost sensors, body contact, or surveillance cameras, the company’s platform relies only on ambient Wi-Fi signals. This allows it to track a person’s vital signs without their cooperation or even awareness.

The implications are vast across multiple sectors. In aged care and healthcare, the system can serve as an ambient safety monitor that is able to detect cardiac anomalies or respiratory distress in real time without infringing on patient privacy.

For defense and tactical surveillance, it provides a passive means of monitoring biometric activity through walls or obstacles, offering a significant edge in scenarios where stealth and non-line-of-sight monitoring are essential.  Border security operations stand to benefit as well, particularly in identifying hidden individuals in vehicles or sealed containers without physical intrusion.

While P2P Group’s commercial ambitions are centered around seamless deployment and unobtrusive intelligence gathering, their developments are being paralleled by government-sponsored initiatives.

On June 10, the Department of Homeland Security’s Science and Technology Directorate (S&T), in collaboration with the Massachusetts Institute of Technology Lincoln Laboratory, announced the successful field testing of the latest generation of DePLife technology.

Originally developed to detect the presence of life through walls using radar, DePLife incorporates motion compensation algorithms that allow it to operate effectively even when the sensor platform – whether handheld or drone-mounted – is subject to minor environmental disturbances such as hand tremors, drone vibrations, or ambient wind.

The ability to adjust for such micro-movements is a critical step forward. Prior through-wall radar systems required near-total stability to distinguish between static environmental features and human presence.

The new algorithms allow for dynamic scanning in active environments like a drone hovering over a building or a responder maneuvering in a high-risk operation without compromising data integrity. And that opens the door to mobile through-wall surveillance in real-world tactical scenarios where motion is inevitable and lives may depend on maintaining a safe standoff distance. Already, law enforcement agencies and the Federal Bureau of Investigation have begun acquiring units, with more deployments expected nationwide.

At a technical level, the methods employed by P2P Group and DePLife differ. One uses Wi-Fi signal disruption analysis while the other employs radar wave reflection. Still, the underlying intent is strikingly similar. Both extract biometric data from otherwise invisible patterns in the environment. Both technologies are converging on the same frontier, the non-invasive detection of life signs under circumstances where conventional methods would be impractical, unsafe, or socially unacceptable.

What is particularly compelling is the complementary nature of these technologies. P2P Group’s platform excels in Wi-Fi-rich environments such as buildings, urban settings, and infrastructure-heavy spaces where Wi-Fi signals are omnipresent and stable. DePLife, on the other hand, leverages radar and is optimized for law enforcement and rescue operations, especially in scenarios with physical barriers, such as walls or debris.

Together, they map out a future in which the sensing of human presence and condition is not bound by physical access, line of sight, or even subject cooperation. The capacity to detect a person hiding inside a sealed container, a wall cavity, or a collapsed building can now be fulfilled with off-the-shelf hardware enhanced by advanced algorithms.

Both developments raise profound questions about the balance between utility and oversight. P2P Group has made a point of emphasizing that their technology avoids invasive surveillance, meaning no cameras, no microphones, and no wearables are required.

This ostensibly protects individual privacy, but the system’s very ability to function covertly and autonomously introduces risks with regard to who controls the data and how is consent managed in environments where sensing occurs ambiently. These are not hypothetical concerns, especially as P2P Group moves to commercialize its platform and pursue intellectual property protections, signaling readiness to scale its solution globally.

Similarly, DePLife’s law enforcement applications, while grounded in the goal of officer safety and situational awareness, tread a narrow line. The system’s ability to scan interiors without physical entry or a warrant raises potential Fourth Amendment challenges, particularly in domestic contexts where the boundary between exigent need and privacy violation is not always clear. As the system expands to include major motion compensation – enabling scans during full movement, including by flying drones – the urgency to establish policy frameworks and legal guardrails will only grow.

Despite these concerns, the technological momentum is undeniable. P2P Group’s advances build on previous academic research such as the “FarSense” system, which demonstrated similar respiration tracking using antenna arrays and signal processing techniques. But where FarSense remained in the realm of research, P2P is pushing its capabilities into the commercial market with an emphasis on simplicity and deployability.

Likewise, DePLife’s transformation from a stationary radar system to a mobile, adaptive tool represents a rare example of federal research translating quickly into operational readiness. In both cases, the culmination of years of foundational research is finally maturing into tools that are effective, scalable, and ready for deployment.

The larger narrative is not about one company or one government project, but about the emergence of a new paradigm in sensing, one that replaces physical contact with ambient signal analysis that can operate invisibly and persistently, and one that redefines the spatial and ethical boundaries of biometric monitoring.

As P2P Group prepares for broader commercial rollout and DHS refines the next iteration of DePLife with upgraded motion compensation algorithms, the convergence between the public and private sectors in biometric intelligence is accelerating. This interplay suggests not only a shared technological trajectory, but also a shared responsibility to ensure that these powerful new capabilities are not misused.
