Hidden Camera Detector Pro++ vs FourScan

A professional hidden camera detection tool built for privacy-conscious travelers and individuals. Whether you're staying at a hotel, vacation rental, or using a public changing room, this app helps you quickly scan your surroundings for concealed surveillance devices. Four core detection technologies work together to provide comprehensive coverage: 【MAGNETIC FIELD DETECTION】 Uses your phone's magnetometer to detect abnormal magnetic signals emitted by hidden electronic devices. An intuitive gauge displays real-time field intensity with haptic alerts when anomalies are found. 【INFRARED DETECTION】 Captures infrared light invisible to the naked eye through your phone's camera. Automatically identifies and marks IR light sources commonly used by hidden cameras for night vision. Adjustable sensitivity for different lighting conditions. 【WIFI NETWORK SCANNING】 Scans all devices on your WiFi network and probes common camera ports. Calculates a suspicion score based on open ports, device names, and service types. Color-coded risk levels for instant assessment. 【BLUETOOTH SCANNING】 Detects nearby Bluetooth devices and evaluates suspicion levels based on device characteristics. Displays real-time signal strength to help estimate device distance and direction. 【DETECTION GUIDE】 Built-in guide with professional tips for physical inspection, teaching you how to systematically check common hiding spots — even without tools. Key Features: - All-in-one: magnetic, infrared, WiFi, and Bluetooth scanning - Easy to use: no technical expertise required - Real-time feedback with haptic alerts - Intuitive visual gauges and color-coded indicators - Privacy first: all detection performed locally, no data uploaded Important Notice: This app uses your phone's built-in sensors for auxiliary detection.
