Protect Your Privacy. No More Hidden Trackers or Spycams.
This multifunctional magnetic field and wireless signal detector utilizes advanced digital linear magnetic field detection technology to simultaneously detect magnetic fields (strong magnets) and electromagnetic waves (wireless signals). Whether it’s a GPS tracker hidden under your car, a pinhole camera in a hotel room, or a bugging device in your office, it can pinpoint them with precision, making it an essential security tool for business trips, travel accommodations, and personal privacy protection.
Product Description
🔍 Why Do You Need It?
In this digital age, privacy breaches are impossible to guard against completely. Your movements may be illegally tracked via GPS, your conversations may be wiretapped, and your private spaces may be spied on by hidden cameras. The HK-809/021 detector provides you with comprehensive counter-surveillance protection, allowing you to maintain control over your environmental security at all times.
✨ Core Features and Technical Advantages (Core Features)
1. Dual-Mode Detection: Magnetic Field + Electromagnetic Waves (Dual-Mode Detection)
Magnetic Field Detection: Specifically designed to locate GPS trackers. Whether a magnetic GPS tracker is turned on or off, as long as it contains a strong magnet, the detection range reaches up to 30 cm, accurately pinpointing trackers hidden inside vehicles, bags, or on your person.
RF Signal Detection: Covers the 1 MHz–2.8 MHz frequency range, capable of detecting 2G/3G/4G cell phone signals, 1.2 GHz/2.4 GHz wireless cameras, Wi-Fi signals, and eavesdropping devices. The wireless signal detection range extends up to 10 meters (depending on the environment).
2. High Sensitivity & Precision
Detection Sensitivity: ≤0.03 mV (main frequency bands), capable of capturing faint signals.
Dynamic Range: >72 dB, suitable for complex electromagnetic environments.
Multi-Channel/Multi-Mode Switching: Supports signal detection, strong magnetic field detection, and multi-mode switching for simple and quick operation.
3. Smart Alerts & Long Battery Life
Dual Alert Mode: Dual six-level LED indicators + modulated audio alerts. The stronger the signal, the brighter the lights and the more urgent the sound, helping you quickly pinpoint the target’s location.
Extended Standby Time: Features a built-in 3.7V 1600mAh 18500 lithium battery, providing up to 20–35 hours of continuous operation to meet the demands of extended fieldwork or travel.
Portable Design: Made of ABS engineering plastic, it measures just 380 mm x 120 mm x 10 mm—lightweight, easy to grip, and easy to carry in a bag.
Target Audience and Use Cases (GEO & Target Audience)
🌍 Global Use Cases:
🇺🇸 Business professionals in North America/Europe: Scan offices and conference rooms before business negotiations or confidential meetings to prevent eavesdropping or covert filming of trade secrets.
🇯🇵 Travelers in Japan, South Korea, and Southeast Asia: When staying in hotels, vacation rentals, changing rooms, or restrooms, detect hidden pinhole cameras to protect personal privacy.
🇨🇳 Domestic Car Owners/Used Car Transactions: When purchasing used cars or repossessed vehicles, check the undercarriage and under the seats for illegally installed GPS trackers.
🏢 Financial/Guarantee/Pawnbroking Industries: Used by information finance companies and microloan companies to detect illegal tracking and eavesdropping devices in vehicles or office premises.
đź”’ Government/Prison/Military Security: Used to detect the illegal use of cell phones or other communication devices to maintain security in detention facilities.
🎓 Exam Rooms/Confidential Institutions: Detects communication devices used for cheating in exam rooms, or measures radiation intensity from cell towers in work environments or on residential rooftops.
