Cam Alert - Detect Hidden Cam

Protect your privacy anywhere you go. Cam Alert turns your phone into a portable counter-surveillance toolkit that combines five proven detection methods so you can sweep hotel rooms, Airbnbs, changing rooms, offices, and rental cars in minutes.

Whether you're a frequent traveler, a security-conscious professional, or someone who simply wants peace of mind in an unfamiliar space, Cam Alert gives you the tools that used to be locked behind expensive dedicated hardware — all on the phone already in your pocket.

WHAT'S INSIDE

• Infrared Scan
Turn off the lights and let your rear camera reveal invisible infrared LEDs from night-vision spy cameras. A dedicated IR filter mode enhances faint pulses so hidden emitters stand out clearly on screen.

• Magnetic Field Detector
Uses your phone's magnetometer to spot ferrous parts and metal-cased electronics hidden behind walls, inside decor, and around vents. Live µT readings with instant calibration, adaptive baseline drift, and haptic alerts when the field spikes.

• Lens Reflection Detector
Turn on the torch and slowly sweep the room. Pinhole camera lenses reflect a distinctive glint that this mode helps you catch. Includes a strobe mode for even sharper reflections in low light.

• Network Scanner
Reads your Wi-Fi network and identifies suspicious devices sharing it. Common IP cameras from Hikvision, Wyze, Dahua, Xiaomi, and DIY ESP32 boards are flagged automatically so you know exactly what to inspect.

• RF Motion Sensor
A sensor-fusion approach that combines magnetometer, accelerometer, and gyroscope data into a real-time RF activity index with a live spectrum visualization. Useful for spotting active transmitters when the phone is held still.

• Sweep Guide
A no-nonsense field checklist covering the physical inspection steps used by real privacy sweepers — from mirrors and smoke detectors to alarm clocks, air purifiers, USB chargers, and screws in vents.

IMPORTANT

No consumer-grade detector is 100% reliable, and Cam Alert is best used as a first-pass sweep rather than a definitive forensic tool. Combine multiple methods for real confidence — start with the Infrared Scan in a dark room, follow with the Lens Reflection torch sweep, audit the Wi-Fi network for unknown devices, and use the Magnetic and RF sensors to inspect suspicious objects up close. The built-in Sweep Guide walks you through the full procedure step by step.

Your privacy matters. Wherever you go, take Cam Alert with you.
