IS SOMEONE WATCHING YOU? ENHANCE YOUR PRIVACY AWARENESS. Assist your search for potential privacy threats. Spycam Detector Pro is a utility suite designed to help you analyze your surroundings for magnetic anomalies, optical reflections, and suspicious devices on your network in hotels, changing rooms, and rental apartments. Using the device's built-in sensors and Augmented Reality (AR) visualization, we provide essential tools to assist your manual inspection of any space. KEY FEATURES: ● OPTICAL LENS ASSISTANT Use the visual filter to help you spot reflections that may indicate camera lenses. The red filter is designed to improve contrast, assisting you in identifying glints from potential hidden objects during your physical search. ● MAGNETIC FIELD ANALYZER (EMF) Electronic devices often emit magnetic signals. This tool utilizes your device’s magnetometer to display magnetic field levels, helping you identify anomalies near walls, smoke detectors, or mirrors that warrant further inspection. ● NETWORK & WI-FI SCANNER Unknown devices on the Wi-Fi? Scan the local network to list connected devices. This helps you identify suspicious or unrecognized IP connections sharing the network with you. ● AR SENSOR MODE Visualize magnetic sensor data through your camera view. This AR feature helps you pinpoint the general direction of magnetic signals to focus your manual search. ● SECURITY TIPS & GUIDE Not sure where to look? Our built-in guide provides common checklists and suggests places to manually inspect, helping you perform a more thorough search. WHERE TO SCAN? Hotels & Rentals: Check alarm clocks, smoke detectors, and TV sets. Changing Rooms: Inspect mirrors and hangers. Offices: Check meeting rooms for unusual electronics. WHY CHOOSE SPYCAM DETECTOR PRO? • Comprehensive analysis toolkit (Visual, Magnetic, Network). • Intuitive interface for quick environmental checks. • Real-time sensor feedback. IMPORTANT DISCLAIMER: This application is designed as a helper tool and utilizes your device's internal sensors (Magnetometer, Camera, Wi-Fi). It is not a replacement for professional physical inspection. Detection accuracy depends on the specific environment and the sensor capabilities of your device. We do not guarantee the detection of all hidden devices.
