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 a low noise amplifier (LNA) and high-performance antenna to capture weak signals and improve detection capability. Intelligent signal recognition and classification Automatic marking function: built-in signal library can automatically identify and mark known wireless device signals such as Wi-Fi, Bluetooth, GSM, CDMA, etc., helping to 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), assisting users in analyzing band occupancy. Multi-mode detection for complex environments RF signal detection: helps locate wireless cameras, hidden transmitters, GPS trackers, and other RF-emitting devices. Infrared camera detection: detects hidden pinhole cameras using infrared laser scanning (requires infrared detection capability). Magnetic field detection: helps identify magnetic 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 sound, light, and vibration notifications when an unknown signal is detected. Portable design with long battery life Lightweight and portable: compact and easy to carry, suitable for use in hotels, conference rooms, vehicles, and other locations. Extended standby time: built-in high-capacity battery supports up to 20 days of standby, ideal for extended use.
