The U-C3 Professional Wireless Signal Detector is a top-tier, independently developed RF security inspection device designed for comprehensive privacy protection and counter-surveillance. It excels in detecting and locating a vast array of wireless threats across a wide frequency spectrum from 1MHz to 6GHz. Its core capability includes full-band scanning of global 2G, 3G, 4G, and the latest 5G cellular signals, as well as 2.4GHz Wi-Fi and Bluetooth protocols. Equipped with a 4.3-inch color touchscreen, intuitive menu-driven operation, and advanced signal logging functions, the U-C3 Pro offers unparalleled accuracy and sensitivity for identifying hidden cameras, GPS trackers, audio bugs, and illicit communication devices. It is the trusted choice for professional TSCM (Technical Surveillance Counter-Measures) operations, corporate security, and personal privacy audits, ensuring your environment is free from wireless eavesdropping.
Rapid Signal Screening: Quickly scans and detects wireless communication signals within the monitored area. Suspicious Camera Detection: Performs demodulation and analysis of target signals to accurately identify and alert on suspected WiFi based hidden cameras. Suspicious Tag Alert: Analyzes characteristic fields from Bluetooth scan results to determine the presence of suspicious tracking tags or eavesdropping devices within range. Suspicious FM Bug Detection: Independently scans and analyzes FM signals from other communication protocols and generates alerts when suspected FM eavesdropping signals are detected. Full-Standard, Full-Band Signal Discovery: Detects all major cellular communication signals within range, including 2G/3G/4G/5G networks, as well as 2.4 GHz WiFi signals.
