Real threat or false alarm?

In professional security inspections, detecting a signal is only the first step.
The real challenge is identifying its source, evaluating the risk, and deciding what action to take.

A reliable detection process should help your team:

• Locate suspicious RF signals
• Reduce false alarms
• Analyze signal characteristics
• Make faster, evidence-based decisions

For hotels, offices, meeting rooms, and sensitive facilities, accurate detection matters.

What is the biggest challenge in your security inspections: signal detection, source location, or false-alarm reduction?

See Beyond the Signal. 🔍

The TFN PHC12 Series RF Detector combines wireless signal detection with thermal imaging to provide an additional visual aid when locating potential hidden surveillance devices.

🌡️ Thermal Imaging — helps identify abnormal heat signatures
📡 Radio Frequency Analysis — detects and analyzes wireless signals
🎯 Locate More Efficiently — use RF and thermal information together to narrow down suspicious areas

For professional TSCM inspections, security sweeps, and counter-surveillance applications, PHC12 provides a more comprehensive approach to finding potential listening devices and other wireless transmitters.

Common RF detector vs TFN professional RF detector — what’s the real difference?

Many RF detectors look similar, but performance can be very different.

The difference is not only about detecting a signal. It’s about:
✔ How weak a signal can be detected
✔ How wide the frequency range is
✔ How well it handles interference
✔ How accurately you can locate the source

For professional security inspections, the right detection tool makes a big difference.
