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: Adopting low noise amplifier (LNA) and high performance antenna, it can capture weak signals and ensure that hidden devices have nothing to hide. Intelligent Signal Recognition and Classification Automatic marking function: Built-in signal feature library can automatically identify and mark known wireless device signals such as Wi-Fi, Bluetooth, GSM, CDMA, etc., and quickly distinguish between legal and illegal signal sources. Spectrum visualisation: visualisation of signal distribution through spectrum graph (frequency on horizontal axis, signal strength on vertical axis), assisting users to analyse band occupancy. Multi-mode Detection, Adapt to Complex Scenarios RF signal detection: accurately locate wireless cameras, bugs, GPS trackers and other devices. Infrared camera detection: detect hidden pinhole cameras through infrared laser scanning (need to cooperate with infrared detection function). Magnetic field detection: identify magnetised GPS trackers and other devices. High Sensitivity Adjustment and Alarm Function 6-level sensitivity adjustment: Users can adjust the detection sensitivity according to the level of environmental interference to avoid false alarms. Sound, light and vibration alarm: When detecting an unknown signal, the device alerts the user through sound, vibration and light to ensure a timely response. Portable Design and Long Life Lightweight and portable: the device is compact and lightweight, easy to carry around, suitable for hotels, conference rooms, cars and other scenes. Ultra-long standby: Built-in high-capacity battery supports 20 days of standby time to meet the needs of long-time use.
