Are you looking for a truly high-end, professional-level detector that can detect any unwanted bugs, hidden cameras or RF signals? Then the BugHunter BH-04 Professional RF GSM bug and hidden camera detector is the one for you! This detector is the absolute top among detectors, which has been specially designed for professional use in the security sector. It is a full-featured counter-espionage device aimed at detecting wireless spying devices (bugs, hidden microphones and cameras, walkie-talkies, etc.), both digital and analogue. The device features an extra wide frequency range, two independent search channels with separate antennas, and a built-in frequency meter for identifying the frequencies of detected spiders. This professional detector is characterized by the following features: 
1. It has two independent channels operating in the frequency range of 10 to 8000 MHz. Each channel has its own antenna and specific purpose. The ANT1 channel is designed to operate in the 10 to 2400 MHz range in which most spy equipment operates. It features high sensitivity and a wide dynamic range (up to 70 dB), making it capable of detecting even the weakest eavesdroppers. ANT2 is a high-frequency (from 2400 to 8000 MHz) and high-speed channel capable of detecting even nanosecond signals (ANT2 applications - 5.8 GHz digital and analog cameras, 2.4 and 5 GHz Wi-Fi and Bluetooth modules, etc.). The BugHunter BH-04 therefore operates over the entire frequency range without interruptions.
2. Built-in frequency meter. The device is equipped with a highly sensitive and high-speed frequency meter. It identifies the most popular signal types including GSM, DECT, BLUETOOTH, WLAN, 3G/4G/5G.
3. The detector has three detection modes: search, oscillograph and security mode.
4. Convenient and informative color LCD display (320 x 340px). When searching for spy platforms, the screen displays two graphs: peak values (red) and average values (green) of detected signals.
5. Automatic and manual adjustment of the sensitivity threshold and vibration signal. If necessary, the sensitivity of the device can be adjusted so that the graphs do not change. The vibration signal threshold can also be adjusted.
6. Background subtraction function to eliminate interference. This is a full-fledged alternative to filtering, as the latter only attenuates strong GSM and Wi-Fi signals that prevent the detector from locating weak spy platforms.
7. Log generation with the possibility of uploading to a PC. In security mode, the device maintains a database of alerts (recorded radio signals) that is stored in memory. The device has 4 databases with 2000 logs in each. Each database is capable of storing alerts registered during one session in security mode. It is then repeatedly updated with new data.

8. Acoustic indication of the detected signal. The device is equipped with an acoustic detection function, which means that the detected signal is transmitted to the built-in speakers of the device or to the headphones.
9. Autonomous power supply from Li-Pol battery. The device is powered by a built-in rechargeable battery. The battery can be recharged using a 110/220 V power adapter or via the USB port of a computer.
10. Rigid metal housing. Aluminum alloy housing protects the device from mechanical damage.
