Ultra-wide frequency band coverage, accurate detection Wide frequency range: supports 1MHz-6GHz band scanning, covering 2G/3G/4G/5G mobile signals, Wi-Fi, Bluetooth, GPS, wireless camera and other common wireless device signals. High sensitivity reception: features low noise amplifier (LNA) and high-performance antenna to capture weak signals and enhance detection performance. Intelligent signal recognition and classification Automatic marking function: built-in signal feature library automatically identifies and marks known wireless device signals such as Wi-Fi, Bluetooth, GSM, CDMA, and helps distinguish between common and unknown signal sources. Spectrum visualization: displays signal distribution through a spectrum graph (frequency on horizontal axis, signal strength on vertical axis) to assist in analyzing band occupancy. Multi-mode detection for complex environments RF signal detection: helps locate wireless cameras, hidden transmitters, GPS trackers, and similar devices. Infrared camera detection: detects hidden pinhole cameras using infrared laser scanning (requires infrared detection capability). Magnetic field detection: helps identify magnetized objects such as certain GPS tracking devices. Adjustable sensitivity and alert functions 6-level sensitivity adjustment: allows users to adjust detection sensitivity based on environmental conditions to reduce false alerts. Audio, visual, and vibration alerts: provides multi-mode notifications when an unknown signal is detected to support prompt response. Portable design with extended battery life Lightweight and portable: compact design for easy carrying, suitable for use in hotels, conference rooms, vehicles, and similar environments. Long standby time: built-in high-capacity battery supports up to 20 days of standby to accommodate extended usage needs.
