SZMID - BQX-B04 (Handheld Wireless Signal Detector): Comprehensive Detection for Modern Wireless Devices
The SZMID - BQX-B04 is a versatile and high-performance handheld wireless signal detector, specifically designed to identify and locate a broad spectrum of radio devices, including cell phones, smartphones, GPS trackers, GSM bugs, 3G/4G/5G video transmission devices, Bluetooth peripherals, and Wi-Fi hotspots. Equipped with global cellular network coverage, it can effectively detect radio signals in diverse regional environments, making it suitable for international use and varied application scenarios.
This advanced device features separate detection modules for the 2.4GHz and 5GHz frequency bands, allowing it to accurately distinguish and pinpoint different radio devices, such as the latest generation of Wi-Fi and Bluetooth devices, video transmitters, and other communication technologies. It is particularly adept at locating Wi-Fi 2.4G hotspots and their connected terminal devices, as well as BLE (Bluetooth Low Energy) devices, including popular trackers like Apple AirTag, Huawei Tag, and other similar Tag devices.
The BQX-B04 is engineered with enhanced sensitivity across all supported frequency bands, enabling it to detect even weak signals from up to 50 meters away. This makes it a reliable tool for detecting and neutralizing eavesdropping devices and unauthorized communication tools in sensitive environments. Additionally, the detector supports comprehensive mobile signal logging for up to one hour, providing a detailed record of detected signals that can be viewed on the device's large 4.3-inch color TFT capacitive touchscreen or downloaded via SD card for further analysis and long-term storage.
With its intuitive menu-driven operation, sound signal strength “drop” warning mode, and a rechargeable internal lithium polymer battery pack, the BQX-B04 is designed for ease of use and maximum portability. Whether used for security inspections, corporate surveillance, or personal protection, this detector provides comprehensive coverage and unparalleled accuracy, ensuring that no unauthorized radio signal goes undetected.
