Inspect hotels, rentals, offices, and unfamiliar rooms with one clear, guided workflow. Hidden Camera Detector combines lens-reflection tools, nearby Bluetooth and Wi‑Fi scanning, magnetic-field readings, and a room-by-room checklist. Use each signal as part of a structured inspection designed to reduce guesswork and highlight what deserves a closer look. ONE WORKFLOW. MULTIPLE SIGNALS. LENS CHECK Use the live camera view and multiple filters to make reflections and possible lens glints easier to notice. Adjust exposure, switch cameras, control the flashlight, or use Color Cycle, Brightness Ramp, and Auto Sweep for different visual conditions. NEARBY DEVICES Use Radar to review Bluetooth devices with signal-strength bars, suspicious indicators, and signal-lost detection. Scan reachable addresses on the local Wi‑Fi network, view your local IP, and identify devices worth investigating. MAGNETIC FIELD Monitor live Bx, By, and Bz readings, total field strength in microtesla, and changes over time on a rolling chart to guide a closer inspection. GUIDED ROOM CHECK Choose a Quick, Balanced, or Thorough scan. Build a checklist around your location, room size, and lighting, then work area by area with progress tracking and practical tips for common hiding places. REPORTED LOCATIONS Explore a map of publicly reported hidden-camera incidents compiled from open online sources. PRIVATE BY DESIGN Lens detection does not record or send images. Permissions are requested only when needed: - Camera: Lens check - Bluetooth: Nearby-device scan - Local Network: Wi‑Fi scan - Notifications: Optional reminders - Location: Optional map position IMPORTANT Hidden Camera Detector makes the most of your phone's camera, Bluetooth, Wi‑Fi, and sensors to help you spot signs of hidden cameras. It is a practical first step for everyday checks, but it does not replace specialized detection equipment or a professional security inspection. Download Hidden Camera Detector and inspect your next space with a clearer, more repeatable process.
