Detect Malicious Surveillance Devices

Detect infrequent and low powered signals with fast sweep rates and advanced triggering capabilities of thinkRF software-defined spectrum analysis solutions.

24/7 – Continuous RF Surveillance

Technical Surveillance Countermeasures (TSCM) plays an important role in detecting, locating, and removing malicious surveillance devices intended to capture and transmit private information from corporate offices, governments, and other secure facilities. TSCM professionals face a unique challenge in that they are often unsure what type of signal they are looking for, or whether a signal is present at all. Malicious actors have become more sophisticated, transmitting in short bursts at irregular intervals, making detection even more difficult.
