Two Independent Detection Channels for Maximum Accuracy

The key advantage of this device is its two independent detection channels operating across different frequency ranges. The ANT1 channel covers frequencies from 10 MHz to 2400 MHz, where most listening devices, wireless microphones, and analog transmitters operate. It offers outstanding sensitivity and a dynamic range of up to 70 dB, allowing it to detect even extremely weak RF signals. The ANT2 channel operates from 2400 MHz to 8000 MHz and is designed to detect modern high-frequency devices such as Wi-Fi networks, Bluetooth modules, and digital cameras operating on the 5.8 GHz band. As a result, the Professional RF Detector BugHunter BH-04 provides complete frequency coverage without blind spots.

Intelligent Signal Identification and Integrated Frequency Counter

The detector is equipped with a high-precision frequency counter capable of automatically identifying the most commonly used wireless communication technologies. It recognizes GSM, DECT, Bluetooth, WLAN, as well as 3G, 4G, and 5G mobile networks. This significantly simplifies signal source identification and speeds up professional security inspections. Thanks to its precise frequency analysis, users can efficiently locate active surveillance devices while distinguishing them from legitimate wireless equipment operating nearby.

Three Professional Detection Modes

The Professional RF Detector BugHunter BH-04 offers three operating modes tailored to different inspection scenarios. Search Mode is used for actively locating wireless surveillance devices by displaying both peak and average signal levels graphically. Oscilloscope Mode allows detailed waveform analysis of detected RF signals, helping users identify the type of transmitter more accurately. Security Mode is designed for continuous RF environment monitoring. The detector memorizes the existing radio environment and immediately alerts the user whenever a new active signal appears using audible alarms, vibration, or visual notifications on the display.

Professional Features for Security Inspections

The detector features a 320 × 340 pixel color LCD display, automatic and manual sensitivity adjustment, and a background subtraction function that effectively removes interference caused by strong GSM and Wi-Fi signals. It can also store detected events in four internal databases, each capable of recording up to 2,000 events, which can later be exported to a computer for further analysis. The built-in rechargeable Li-Polymer battery allows convenient portable operation and can be charged via the supplied AC adapter or USB connection. Its rugged aluminum enclosure ensures long-term durability, making the Professional RF Detector BugHunter BH-04 ideal for demanding professional use.
