WiFi Scanner: Device Detector Stay aware of your surroundings. Device Detector turns your phone into a powerful scanning tool that helps you check for hidden cameras and suspicious devices wherever you go โ€” hotels, rentals, gyms, restrooms, or any private space. Using a combination of wireless network analysis, Bluetooth detection, magnetic field sensing, and infrared scanning, the app gives you practical tools to feel more confident about your privacy. โ–ถ KEY FEATURES - Wi-Fi Network Scanner Scan your current Wi-Fi network to discover connected devices. The app identifies gadgets that could potentially be network cameras or other surveillance equipment sharing your connection. - Bluetooth Device Detection Detect nearby Bluetooth-enabled devices in your environment. Spot unfamiliar or unnamed devices that may warrant a closer look, especially in places where you expect privacy. - Magnetic Field Detector Leverage your phone's magnetometer to pick up on magnetic anomalies. Hidden cameras and electronic devices often contain small magnets or components that produce detectable magnetic signatures โ€” particularly behind walls, mirrors, or inside everyday objects. - Infrared (IR) Detector Use your phone's camera to detect infrared light sources invisible to the naked eye. Many surveillance cameras rely on IR LEDs for night vision, and this mode helps you spot them even in complete darkness. โ–ถHOW TO USE 1. Pick a scan mode โ€” Wi-Fi, Bluetooth, Magnetic, or IR 2.
