NSpy — Find Hidden Cameras Before They Find You

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.

Audio Bug & Mic Detection

NSpy flags network devices that contain microphones and includes built-in guidance for locating hidden audio bugs disguised in power strips, smoke detectors, and outlets.

Works Without Wi-Fi

The infrared and magnetic detectors run entirely offline with no network connection required, so you can sweep anywhere — even when there's no Wi-Fi to join.

How It Works

Sweep Any Room in 3 Simple Steps

No expertise needed. NSpy makes counter-surveillance sweeps easy enough for any traveler, guest, or host.

1

Connect to the Local Wi-Fi

Join the local Wi-Fi network in the hotel room, Airbnb, or space you want to check — NSpy needs the same network to find suspicious cameras.

2

Run a Detection Sweep

Open NSpy and run any of the three detection methods — network scan, infrared camera viewer, or magnetic field detector — to sweep the room end to end.

3

Review & Investigate Results

Review NSpy's classified results and inspect any device or signal flagged as suspicious to confirm whether it's a genuine privacy threat.

FAQ

Got Questions? We Have Answers

Everything you need to know about NSpy.

What is NSpy?
NSpy is a hidden camera and spy device detector for iPhone, iPad, and Android. It combines Wi-Fi network scanning, infrared detection, and magnetic field sensing into a single privacy toolkit so travelers and renters can sweep any room for hidden surveillance devices.
Is NSpy free to download?
Yes — NSpy is free to download and includes basic scanning. An optional Pro upgrade unlocks visibility into all detected devices and the full infrared and magnetic detection capabilities.
How does the NSpy network scanner detect hidden cameras?
NSpy scans the local Wi-Fi network for connected devices and analyzes each one with port scanning (checking common camera ports like 554, 8080, 8443), MAC address vendor lookup, and known camera signatures to classify devices as routers, cameras, or unknown.
How does NSpy's infrared detection work?
Many hidden cameras use infrared LEDs for night vision. These IR lights are invisible to the naked eye but show up on a phone camera. NSpy uses the rear camera to help users spot the bright telltale spots in a darkened room.
What does the NSpy magnetic field detector do?
Electronic devices like hidden cameras emit small magnetic fields. NSpy reads the phone's built-in magnetometer to detect these fields — as users move the phone toward a hidden device, the gauge climbs, helping pinpoint its location.
Do I need to be on the same Wi-Fi network to use NSpy?
Yes, for the network scan you need to be on the same Wi-Fi network as any potential hidden camera. NSpy's infrared and magnetic detection methods work independently and don't require Wi-Fi.
Can NSpy detect hidden microphones and audio bugs?
Yes. NSpy flags devices on your network that contain microphones — such as rogue smart speakers — and includes a built-in guide for locating hidden audio bugs using radio interference and the magnetic detector. Audio bugs are often disguised inside power strips, smoke detectors, lamps, and outlets.
