ACU-S1
Tactical Thermal Intelligence
High-Fidelity Thermography. 5G Connectivity.
Forensic Clarity.
The invisible threat demands an invisible response.
Modern eavesdropping devices have evolved far beyond simple radio transmitters. Today’s implants use burst transmission, frequency hopping, and deep-sleep modes that make them virtually undetectable to standard RF sweeps. However, one thing every active electronic circuit cannot hide is heat. Even in standby, a covert device generates a thermal signature—and the ACU-S1 is engineered to find it. Built on the rugged IP68-rated SATIR platform and refined by Acustek’s years of TSCM field expertise, the ACU-S1 is not a consumer gadget—it is a tactical thermal phone designed for the demands of professional counter-surveillance sweeps.
1. The Solution: Fusion II Technology
In a professional TSCM sweep, a “heat map” isn’t enough—you need context. The ACU-S1 features proprietary Fusion II Mix IR technology. Unlike standard thermal cameras that produce blurry blobs of colour, Fusion II superimposes a high-definition pseudo-image overlay directly onto the thermal data.
- See the Detail: Maintain the sharp outlines of screws, labels, and circuit components.
- Locate the Source: Pinpoint exactly which component is generating heat within a device.
- Forensic Evidence: Generate reports that show the heat and the physical object simultaneously - providing undeniable visual proof for the boardroom.
2. Why the ACU-S1 Outperforms the Competition
Most "thermal phones" are consumer-grade gadgets. The ACU-S1 is a field-hardened intelligence tool based on the world-leading platform and refined by Acustek's years of TSCM expertise.

- Visual Camera: 48MP Main sensor for high-fidelity reference photography.
- Processor: Qualcomm Snapdragon 5G for real-time algorithm processing.
- Storage: 256GB Internal / 8GB RAM to handle massive forensic video logs.
- Battery: 7000mAh for grueling 12-hour field operations.
- OS: Secure Android 13 with Over-the-Air (OTA) intelligence updates.
5. The Visual Truth Layer
The ACU-S1 is the visual “Truth Layer” of our NextGen TSCM Kit. While our Dark Compass identifies the signal and our SWORD-24 finds the junction, the ACU-S1 provides the visual confirmation required to close the mission. When you choose Acustek, you choose a legacy of hard work, relentless iteration, and field-proven reliability.
- NextGen TSCM Kit — The complete integrated counter-surveillance ecosystem.
- Dark Compass — Signal Intelligence: identifies the signal.
- SWORD-24 — Physical Intelligence: finds the junction.
