Technical Surveillance Countermeasures - TSCM - is the professional discipline of detecting and neutralising covert surveillance technology. It is the same methodology used to secure government buildings, corporate boardrooms, and embassy communications. Safe Sweep applies it to domestic violence contexts.

// 01 - What TSCM Means
TSCM - Technical Surveillance Countermeasures - is the professional practice of systematically detecting, identifying, and neutralising covert surveillance technology. It was developed by intelligence and government security agencies and has been applied in classified and sensitive environments for decades.
TSCM is not bug-sweeping in the consumer sense. It is a structured, methodological discipline that uses a combination of specialist detection equipment, technical expertise, and operational procedure to find what passive inspection and consumer technology cannot.
Active RF transmitters. GSM cellular audio devices. Passive recording devices. Hidden cameras including pinhole lenses. GPS and Bluetooth tracking devices. Non-transmitting dormant devices. Electronic components concealed inside objects.
Any app on a potentially compromised phone. Any device that is powered off or in standby. Any camera too small to see at normal viewing distance. Any RF transmission outside the frequency range of consumer detectors. Any device hardwired to building infrastructure.
// 02 - The Methods Safe Sweep Uses
Systematic sweep of the radio frequency spectrum from 10 MHz to 12 GHz. Identifies any transmitting device - audio bugs, GSM devices, Wi-Fi cameras, Bluetooth trackers - operating in any frequency band. Provides a complete picture of all RF emissions from the target environment.
10 MHz - 12 GHzTransmits a signal and analyses the harmonic response. Electronic components - transistors, diodes, integrated circuits - produce a characteristic harmonic signature regardless of whether the device is powered on. NLJD finds devices that are completely powered off and emit no signal whatsoever.
Passive DevicesUses a near-infrared light source and optical detector to identify lens reflections from camera lenses hidden inside objects. Finds pinhole cameras at 1-2mm diameter that are completely invisible to the naked eye in normal lighting conditions.
Hidden CamerasElectronic devices generate heat. Thermal imaging identifies heat signatures inside objects that should not have any. Used to locate devices concealed inside walls, ceilings, furniture, and appliances.
Heat Detection// 03 - Why It Matters in Domestic Violence Contexts
The surveillance technology now available commercially - AirTags, pinhole cameras in USB chargers, GSM audio bugs sold openly online - is the same technology that was, until recently, only accessible to intelligence agencies and corporate investigators. The price of these devices has collapsed. Their availability is unrestricted.
At the same time, the detection technology that keeps pace with these threats - NLJD, full-spectrum RF analysis, optical lens detection - has not. There is no consumer product that can do what professional TSCM equipment does. There is no app that finds a powered-off recording device. There is no visual inspection that finds a 1mm pinhole lens inside a smoke alarm.
Safe Sweep exists to close that gap for domestic violence victims. We are the only TSCM service in Australia built specifically for this context - with operators trained in trauma-informed practice, documentation prepared for legal proceedings, and pricing accessible to people who are not corporations.
If you suspect surveillance in your home, vehicle, or workplace, Safe Sweep will find what others cannot. Contact us confidentially.
