As a .Voice Recorder Detector, Spy Camera Detector, and Bug Detector Supplier, we offer the RFD-25 at an Affordable Price to help detect a wide range of hidden surveillance threats, including wireless cameras, switched-on audio recorders, and even switched- off magnetic GPS trackers.
Operating within a frequency range of 50 MHz to 6 GHz, the RFD-25 supports the detection of 2G, 3G, 4G, 5G, and 2.4GHz Wi-Fi devices. Its electromagnetic wave detection function enables users to locate hidden voice recorders or spy devices even if they are in standby or airplane mode. This makes it an ideal choice for security professionals, travelers, business executives, hotel guests, and anyone concerned about privacy intrusion.
The RFD-25 also includes a lens detection feature with six ultra-bright LEDs that reflect off camera lenses, making it easy to spot hidden pinhole cameras concealed in everyday objects like smoke detectors, clocks, or picture frames. Its lightweight and portable design (only 75g) allows for one-handed operation, and it can even be attached to poles or selfie sticks for scanning hard-to-reach areas like ceiling lights or ventilation grills.
Key features include:
• Dual-mode detection: RF signal scanning and electromagnetic wave sensing
• Adjustable sensitivity with LED signal strength indicators and vibration alerts
• Magnetic field detection for locating GPS trackers
• Effective range: up to 30 ft for GSM, 23 ft for 5G, and 7 ft for 10mW 2.4 GHz Wi-Fi cameras
As an experienced Bug Detector Supplier, CIU offers good quality, user-friendly security solutions built for professional and personal use. The RFD-25 at affordable price empowers users to perform efficient, accurate sweeps of any environment—home, hotel, vehicle, or office—to uncover unauthorized surveillance threats.
