A major cybersecurity concern has emerged around police technology, with Bluetooth-enabled tasers and body-worn cameras potentially exposing officers to tracking risks in real time.
The issue centres on devices manufactured by Axon, a US-based company whose equipment is used by police forces across Australia and globally. These tools rely on Bluetooth connectivity to trigger functions such as automatic camera activation when a weapon is drawn — but that same feature may unintentionally reveal an officer’s presence.
Detection possible within hundreds of metres
At the heart of the problem is how Bluetooth signals are broadcast. Each device carries a unique identifier, often referred to as a MAC address. In modern smartphones, this identifier is typically randomised to prevent tracking. However, certain police-issued devices appear to broadcast a fixed identifier, making them easier to detect.
Using widely available apps or simple scanning tools, it has been demonstrated that these signals can be picked up from distances of up to 400 metres. Each detection can reveal not only the presence of a device but also details such as its type and identifier.
With repeated scans, movement patterns can be observed, allowing someone to follow a device — and by extension, the officer carrying it — over time.
Real-world implications raise concern
The risks are particularly serious for undercover officers, surveillance teams, and tactical units. Devices taken home or used outside controlled environments may also increase exposure.
Security researchers have warned that the system could be scaled. By placing multiple low-cost Bluetooth scanners across an area, it would be possible to create a network capable of tracking police movement in near real time.
This could allow individuals to detect patrol routes, avoid law enforcement, or even anticipate operations. The concern is that such vulnerabilities could be exploited without advanced technical expertise.
Known issue with limited response
The vulnerability is not entirely new. Reports indicate that warnings were raised as early as 2024, with concerns shared with law enforcement agencies. Despite this, there has been little visible action across multiple jurisdictions.
Some agencies have acknowledged awareness of Bluetooth-related risks but have not confirmed whether officers have been formally informed or whether mitigation measures have been introduced.
Axon has noted in its own documentation that its devices emit detectable Bluetooth and Wi-Fi signals, even when certain “stealth” settings are enabled. This suggests the limitation may be tied to hardware design rather than something that can be easily fixed through software updates.
Why consumer devices are harder to track
The issue highlights a key difference between professional equipment and consumer electronics. Most modern smartphones and wearables use address randomisation, frequently changing their identifiers to prevent long-term tracking.
Devices that do not use this feature — including some specialised or lower-cost hardware — remain significantly more visible when scanned.
This explains why everyday gadgets such as phones are generally more resistant to tracking, while certain dedicated devices may stand out in wireless scans.
Wider implications for connected technology
The situation reflects a broader reality of modern digital life. Any device that emits a wireless signal — Bluetooth, Wi-Fi, or cellular — can theoretically be detected under the right conditions.
While complete invisibility is not realistic, steps such as disabling unused wireless features can reduce exposure. For organisations, however, the challenge lies in balancing functionality with operational security.
Further insight into wireless detection and privacy risks is available through this official cybersecurity guidance, which outlines how such signals can be identified and managed.
As policing increasingly relies on connected technology, the focus is shifting beyond capability to accountability — raising urgent questions about whether the tools designed to protect officers may also be exposing them.
