“I run NSpy every time I check into a hotel or Airbnb. It once flagged a suspicious device on the Wi-Fi at one of my stays. The network scanner is incredibly thorough and gives me real peace of mind.”

Why Choose NSpy
Three Detection Methods in One Privacy Toolkit
NSpy combines network scanning, infrared detection, and magnetic field sensing in a single app — so travelers, renters, and hosts can sweep any room for hidden surveillance devices with confidence.
Wi-Fi Network Scanner
NSpy scans the local Wi-Fi network and lists every connected device, flagging suspicious cameras through port scanning and vendor analysis.
Infrared LED Detection
NSpy uses the phone's rear camera to surface invisible infrared LEDs that hidden night-vision cameras emit, making them appear as bright white spots.
Magnetic Field Detector
NSpy turns the device's magnetometer into a magnetic field detector that pinpoints hidden electronics by sweeping the room in real time.
Automatic Device Classification
NSpy automatically classifies discovered devices as routers, cameras, or unknown using MAC vendor lookup, open ports, and network signatures.
Full Device Details
NSpy shows full details for every device — IP address, MAC address, vendor, hostname, and open ports — so users can investigate anything suspicious.
On-Device Privacy
NSpy keeps every scan local on the device and never sends network information to external servers, protecting user privacy by design.
Real-Time Detection
NSpy provides real-time results with a live infrared feed and a continuously updating magnetic field gauge for instant detection feedback.
Built-In Detection Guides
NSpy ships built-in guides that explain each detection method so users learn the difference between safe devices and genuinely suspicious ones.
