Someone could be tracking you right now.

SentryRF is your digital sixth sense for invisible threats. It turns your Android phone into a powerful scanner that finds hidden trackers, spy cameras, drones, fake WiFi, and more. The AI identifies devices by name — iPhone, AirPods, Galaxy, smartwatch — and learns what's normal around you. When something suspicious appears, you'll know. Everything stays on your phone.

Real threats. Real detection.

These are the situations SentryRF is built for — and how SentryRF responds to each one.

📍

Hidden AirTag in a Bag or Jacket

A small tracker slipped into a pocket, a purse lining, or tucked under a car seat. It silently reports your location through Apple's Find My network — no pairing required.

SentryRF detection → SentryRF identifies the tracker and flags it as not belonging to you. If the same device shows up at your home, your office, and the grocery store, SentryRF sees the pattern and alerts you within minutes.
🚗

GPS Tracker Planted on a Vehicle

A magnetic black box attached under the wheel well or inside the bumper. Invisible from outside the car — broadcasting your every trip.

SentryRF detection → Vehicle Check mode runs a focused BLE scan around your car. It flags any device with an unknown manufacturer or no broadcast name that wasn't present at your previous scan. The proximity analyzer estimates distance — if it's within 2 meters and matches no known device, it's suspicious. Sound Locator guides you to the exact spot.
📷

Hidden Camera in a Rental or Hotel

A pinhole camera inside a smoke detector, alarm clock, or wall fixture. Connected to the property's WiFi or storing footage locally on a hidden network.

SentryRF detection → WiFi scanning identifies devices from known camera vendors on hidden networks, matching hardware signatures against a comprehensive manufacturer database. Physical Sweep mode uses your phone's magnetometer to detect active electronics behind walls, and the light sensor picks up infrared LEDs from night-vision cameras.
🛩️

Surveillance Drone Over Your Property

A drone circling overhead — could be a neighbor, a PI, or someone casing your home. Without Remote ID decoding, you'd never know who's flying it.

SentryRF detection → Decodes the FAA-mandated Remote ID broadcast over Bluetooth. Extracts the manufacturer, model, registration serial number, live GPS coordinates, altitude, ground speed, and — critically — the operator's takeoff position. Identifies 100+ drone manufacturers including DJI, Skydio, Autel, and Parrot.
🕶️

Smart Glasses Recording You

Someone at a meeting, a bar, or a private event wearing Ray-Ban Meta or Snap Spectacles — recording video without anyone's knowledge or consent.

SentryRF detection → SentryRF identifies smart glasses by their wireless signature and maintains a database of recording-capable wearables — including Ray-Ban Meta, Snap Spectacles, and Vuzix. These are flagged as recording devices when detected near you.
📸

License Plate Reader on Your Street

ALPR cameras mounted on poles by private surveillance companies — logging every vehicle that passes, building a searchable database of your movements.

SentryRF detection → SentryRF spots license plate reader cameras and logs each detection with GPS coordinates and timestamps for your records.
🎒

Tracker Slipped Into a Child's Belongings

A Tile, SmartTag, or Chipolo placed in a backpack, lunchbox, or jacket — tracking a child's daily routine between home and school without anyone noticing.

SentryRF detection → SentryRF spots Tile, SmartTag, Chipolo, and other trackers. The AI notices when a device keeps showing up at the same places your child goes — and keeps tracking it even if it tries to hide.
🔍

Hidden Electronics in a Room

Suspected surveillance in an apartment, office, or hotel room — wired cameras, audio bugs, or passive recording devices that don't show up on a Bluetooth scan.

SentryRF detection → Physical Sweep uses your phone's built-in sensors as a sweep kit. The magnetometer detects active electronics behind walls and objects. The microphone picks up ultrasonic emissions (16–22 kHz) from camera circuits. The light sensor finds infrared LEDs from night-vision cameras. EMF spike detection flags powered devices hidden in furniture or fixtures.
📶

Fake WiFi Network at a Hotel or Airport

A rogue access point broadcasting the same network name as the real one — anyone who connects has their traffic intercepted, passwords captured, sessions hijacked.

SentryRF detection → SentryRF checks every WiFi network around you and spots fakes — networks pretending to be your hotel, airport, or coffee shop. It catches multiple types of WiFi attacks and warns you before you connect.
📱

Someone Following You With Their Phone

No tracker needed — a person following you on foot or by car, using their own phone's Bluetooth as an unintentional beacon. Most tracker apps can't detect this.

SentryRF detection → SentryRF tracks devices across locations and time. If the same phone appears at your coffee shop, then your office, then your gym — SentryRF flags the pattern. SentryRF identifies the same device even when it changes its wireless address to hide. This is something no other tracker detection app does.
SentryRF Sound Locator - tracking a suspicious device

Track it down. Physically.

Once SentryRF identifies a suspicious device, the AI-guided Sound Locator helps you find its exact physical location. It uses adaptive per-device calibration — the AI tunes signal parameters for each specific tracker type, adjusting for known transmit power, path loss, and even obstruction detection when a tracker is hidden inside a bag or car panel.

  • AI-adaptive distance estimation tuned per device type
  • Audio beeps get faster as you get closer
  • Real-time trajectory analysis detects approach/recede patterns
  • Works with AirTags, Tiles, SmartTags, and unknown trackers
  • Tracks devices even when they change their address to avoid detection

Your phone already has the sensors.
SentryRF puts them to work.

SentryRF doesn't just list nearby devices. 11 on-device AI models and Google's Gemini Nano watch for patterns that reveal when a device is tracking you — and a growing knowledge base learns from your feedback to get smarter with every scan.
