Mobile Phone RF Detector - 5G/4G Cellular Display

Mobile Phone RF Detector finds spy bugs in meeting rooms and conference spaces by detecting phones transmitting audio or video via cellular networks. LCD screen displays frequency and signal strength in real time, so you can locate hidden phones recording confidential conversations across 2G, 3G, 4G, and 5G bands without guesswork.

Key Features

• Cellular spy bug detection - finds mobile phones transmitting recordings via 2G, 3G, 4G, and 5G networks (700-3600 MHz)
• LCD frequency display - shows exact frequency band and signal strength for precise identification of transmitting phones
• 3 antennas included - multi-directional scanning eliminates blind spots in meeting rooms and offices
• 30 sensitivity levels - Low (00-09), Medium (10-19, default), High (20-29) settings match room size and detection range
• 4 alert modes - Beep, Vibration, Beep+Vibration, or Silent mode with earphones for discreet sweeps
• Detection distance - 5-6 m radius (Low sensitivity) up to 20 m radius (High sensitivity), depending on phone transmission power

Meeting Room Security Sweeps

Scan meeting rooms and boardrooms for mobile phones secretly recording conversations via cellular networks. The 3-antenna system detects phones transmitting audio or video on 2G, 3G, 4G, or 5G bands. LCD display shows detected frequency (e.g., 1800 MHz, 2600 MHz) and signal strength in real time, helping you distinguish between legitimate phones outside the room and spy devices hidden under tables, in ceiling tiles, or behind furniture.

Conference Room Confidentiality

Corporate professionals sweep conference rooms before sensitive meetings to prevent unauthorised recording via mobile phones. Default Medium sensitivity (Level 10-19) scans rooms efficiently without false positives from distant cellular towers. High sensitivity (Level 20-29) pinpoints exact location of phones transmitting recordings. Adjustable alert modes allow silent operation with earphones during active meetings or audible beeps for pre-meeting sweeps.

Compliance & Lawful Use

This device is designed for lawful security sweeps of spaces you own or have authorisation to inspect. Use in meeting rooms, offices, and conference spaces where you have legitimate privacy concerns. Detection of cellular signals does not constitute evidence of illegal surveillance — consult legal counsel if you suspect unlawful recording. Audio and video recording consent laws vary by state in Australia.

Frequently Asked Questions

1. What's the difference between this and VIM-BUGDETECT10?

VIM-BUGDETECT10 is optimised for vehicle sweeps (GPS trackers, audio bugs in cars) with auto environment check for outdoor RF noise and 50 MHz-6 GHz detection range. VIM-BUGDETECT11 is optimised for meeting rooms and offices with LCD frequency display showing exact cellular bands (700-3600 MHz), 3 antennas for room coverage, and 30 sensitivity levels for precise detection. BUGDETECT10 = vehicle specialist, BUGDETECT11 = meeting room specialist.

2. Can this detect WiFi cameras or Bluetooth bugs?

No. This detector scans cellular phone signals only (2G/3G/4G/5G bands from 700-3600 MHz). WiFi cameras (2.4 GHz / 5 GHz) and Bluetooth devices (2.4 GHz) are not detected. The device is specifically designed to find mobile phones recording audio or video via cellular networks. For WiFi/Bluetooth detection or optical lens finding, see VIM-BUGDETECT07 or VIM-BUGDETECT09 with lens finder attachment.

3. How do I know if detected signal is a spy phone or my own phone?

Turn off your phone and other known devices (laptop, tablet, smartwatch) you brought into the room. Re-scan. Remaining signals are either hidden phones or building infrastructure (distant cellular towers, phones in adjacent rooms). Use High sensitivity and follow signal strength meter - strongest signal indicates closest device. LCD shows exact frequency band, which you can compare to your carrier's bands if needed.

4. What's the difference between Low, Medium, and High sensitivity?

Low sensitivity (00-09) scans large rooms up to 20 m radius but may miss weak signals. Medium sensitivity (10-19, default) balances detection range and accuracy for typical meeting rooms. High sensitivity (20-29) detects weak signals within 5-6 m radius for pinpoint location of hidden phones once initial detection confirms presence. Start with Medium for sweeps, increase to High for precise location.

5. Does this work internationally?

Partially. The device is optimised for Australian/European cellular frequencies (700-3600 MHz) which cover most global 2G/3G/4G/5G bands. Some regional cellular bands outside this range (e.g., certain North American 4G bands) may not be detected. Consult your region's cellular frequency allocations if travelling abroad with the device.

6. Can I use this during an active meeting?

Yes. Set alert mode to Silent and plug in wired earphones (included). The device will alert you via earphone audio when it detects phones transmitting. LCD screen shows frequency and signal strength silently. For pre-meeting sweeps, use Beep or Vibration mode for faster scanning without needing to watch the screen constantly.
