How It Works
From suspicion to certainty in four steps
No manuals, no expertise required. SenseRadar guides you from the first tap to a located device.
Which scan should I start with?
Start with the full radar sweep, which runs all 6 layers at once; pick a single layer — WiFi, BLE, optical, ultrasonic, EMF or LiDAR — when you need a targeted check.
How long does a room sweep take?
About 2–4 minutes for a typical hotel room or rental: walk slowly while the 6 layers run, and every signal appears on the radar with its direction and identifier.
How do I find where a signal comes from?
Select the suspicious signal and follow the live strength meter: the reading climbs as you get closer, and around -30 dBm you are physically very close.
What should I do once I find something?
Run the AI risk analysis for a detailed report. If a device is confirmed, do not touch it: photograph it and notify your host or the police.
Every step runs on your device. Nothing you scan is ever uploaded, logged or shared.
Help & usage

Field-tested tips straight from the app's help guide. Results are for informational purposes only.
Hidden camera or tracking device?
To find hidden cameras in fixed locations, use Network, Optical and EMF. For mobile tracking devices (AirTag, etc.) hidden in your bag or vehicle, use the BLE Radar first. Keep in mind that some advanced trackers can digitally hide themselves — if suspicion persists, run an EMF (magnetic) scan over your belongings: the battery and speaker magnet inside the device will trigger a red alert at very close range.
How does the network scan find hidden IP cameras?
Disable your VPN and connect directly to the WiFi network you suspect for the most accurate results. Wait until the scan is complete — all ports must be analyzed. The system detects ordinary phones, routers and hidden IP cameras by examining each device's open ports and communication protocols.
How do I find an AirTag or Bluetooth tracker?
Temporarily disable Bluetooth on your own earphones or smartwatch to avoid confusion. As the signal strength (dBm) approaches -30, you are physically very close to the target. The 'Fixed / Resident' warning points to hardware that has been broadcasting in the room for a long time. Important: some smart trackers like the Apple AirTag can enter a 'ghost mode' against third-party scanners when their owner is nearby. If you see unnamed 'Anonymous BLE' devices with a very strong signal (-30 dBm), it could be a concealed tracker.
How do I spot a hidden camera lens?
Turn the room lights completely off or dim them significantly to spot lens reflections (infrared glares) from hidden cameras. Move your phone slowly across the area. For the best AI analysis result, keep the suspected object centered and sharply in focus within the targeting frame on screen.
What does a magnetic field spike mean?
Uses your phone's magnetometer to measure electromagnetic anomalies. Away from known appliances like televisions or microwave ovens, a sudden spike can reveal that an ordinary picture frame, mirror or smoke detector is concealing electronic hardware. The speaker magnets inside small trackers (AirTag, etc.) that digitally hide themselves will also trigger a red warning when scanned at very close range.
Can my phone detect a listening device?
Emits inaudible sound waves in the 18–22 kHz range through your speaker and listens for echoes via the microphone. A concealed camera, listening device or wireless charging coil can emit a characteristic ultrasonic signature. For the best results, stand still in the room, and close windows and doors. Pets or some Bluetooth speakers may react to the test signal; this is completely normal.
How does LiDAR find a device behind a wall or mirror?
Generates a depth map of surfaces on supported iPhone and Android phones (via LiDAR or ARCore Depth) and detects artificial anomalies. A real wall or picture frame produces a flat, continuous surface profile; a hidden device or cable housing behind it appears as a distinct recessed anomaly. Hold your phone approximately 30–50 cm from the target surface, move it slowly, and make sure the surface is well lit.
How to read your scan results
A flagged device is a lead, not a verdict. Each layer reports what it measures — an unfamiliar device on the network, a strong Bluetooth signal, a magnetic spike, a lens-like reflection — and the next step is to confirm it with a second, independent layer before drawing conclusions.
Many alerts have ordinary explanations. Smart TVs, speakers, routers and printers show up in network and Bluetooth scans; appliances and wiring inside walls raise magnetic readings; glass, chrome and screens can reflect light much like a lens. Check what the object actually is, and whether the signal comes from somewhere it makes sense to be.
The cases worth acting on are the ones where several clues point at the same spot: an unknown device on the network, a reading that climbs as you approach a smoke detector, and a glint in the optical scan from the same place. When that happens, leave the object untouched, photograph it and report it to the host and the police.
FAQ
Frequently asked questions
Everything you want to know about SenseRadar, answered plainly.
How does SenseRadar work?
SenseRadar combines six detection layers — WiFi network analysis, Bluetooth (BLE) scanning, AI-powered optical lens detection, ultrasonic acoustic analysis, EMF measurement and LiDAR structural scanning — using the radios and sensors already built into your phone. Suspicious signals are plotted on a radar view so you can locate their source.
Which devices can it detect?
Hidden WiFi and IP cameras, Bluetooth trackers such as AirTags, active listening and recording devices that emit ultrasonic or electromagnetic signatures, and physical anomalies like cavities behind mirrors or panels where hardware may be embedded.
Does it work offline?
Yes. All six detection layers run entirely on your device, and you can scan in airplane mode. Only two optional features need a connection: the AI Sniper photo analysis and the AI network risk report. The WiFi layer naturally requires joining the local network you want to inspect.
Where does my data go?
Scan results, camera frames and audio analysis stay on your phone, and the app requires no account or sign-up. If you explicitly trigger an optional AI analysis, only anonymized device vendor info — or the single photo you submit with AI Sniper — is sent for processing and is not stored. See the Privacy Policy for details.
Is detection 100% guaranteed?
No tool can honestly promise 100%. Sophisticated devices can be powered off or shielded. SenseRadar's multi-layer approach dramatically raises the odds of detection, and we recommend combining scans with a quick physical inspection of high-risk spots.
