Hidden Camera Detector – Find Spy Cameras & Protect Your Privacy

You can detect a hidden camera using your smartphone with our free detector app. The app uses your phone's magnetic field sensor to identify electronic devices, infrared detection for night-vision cameras, and WiFi scanning for wireless cameras. Simply open the app and scan suspicious areas like smoke detectors, clocks, mirrors, and electrical outlets. The magnetic sensor will alert you when hidden electronics are nearby.

To detect a hidden camera in a smoke detector, use our app's magnetic field scanner. Point your phone at the smoke detector and watch for magnetic spikes that indicate hidden electronics. Look for visual signs like extra holes, unusual weight, or LED lights that shouldn't be there. Spy cameras hidden in smoke detectors are common in hotels and rental properties—our detector identifies them by their electronic signatures.

Finding hidden cameras in smoke detectors requires both visual inspection and technology. First, check if the smoke detector looks different from others in the building. Then use our hidden camera detector app to scan for magnetic field anomalies. Hidden cameras contain motors and electronics that emit detectable magnetic fields. Our app alerts you instantly when suspicious devices are found inside smoke detectors or fire alarms.

Hidden camera detectors work by identifying electronic signatures that all cameras emit. Our app uses three detection methods: magnetic field sensing to find electronic components, infrared scanning to spot night-vision cameras in darkness, and WiFi network analysis to detect wireless streaming cameras. Your smartphone's built-in sensors power these features, making professional-grade detection accessible to everyone.

To spot spy cameras, start by looking for small holes, unusual objects, or devices pointing toward private areas. Then use our detector app to scan with magnetic field and infrared technology. Spy cameras often hide in everyday objects like clocks, phone chargers, picture frames, and smoke detectors. The app reveals hidden electronics that visual inspection alone would miss, especially miniature pinhole cameras.

Yes, hidden camera detectors work effectively when using proper technology. Our app combines magnetic field detection, infrared scanning, and WiFi analysis—the same methods used by professional security experts. With over 1.3 million users and a 4.8-star rating, the app has helped detect thousands of hidden cameras in hotels, vacation rentals, and private spaces worldwide.

The best hidden camera detector combines multiple detection technologies in one easy-to-use app. Our detector stands out with magnetic field sensing, infrared camera detection, WiFi network scanning, and video stream analysis. Unlike single-purpose detectors, our app finds wired cameras, wireless cameras, and night-vision cameras. It's trusted by 1.3+ million users and rated 4.8 stars for accuracy and ease of use.

Quality hidden camera detector apps work by leveraging your smartphone's built-in sensors. Our app uses the magnetometer to detect camera electronics, the camera to spot infrared lights, and network access to find WiFi cameras. Professional detection methods adapted for smartphones provide reliable results. The key is using an app with multiple detection technologies, not just one method.

Detect hidden cameras using a systematic three-step approach: First, visually scan for suspicious objects, unusual holes, or out-of-place items. Second, use our app's magnetic field scanner to locate hidden electronics behind walls and inside objects. Third, scan the WiFi network for unknown streaming devices. Focus on common hiding spots—smoke detectors, clocks, mirrors, electrical outlets, and air vents.

Check for hidden cameras every time you stay in a new location. Use our detector app to scan the room systematically—start with the bedroom and bathroom, focusing on areas facing beds, showers, and changing areas. The magnetic scanner reveals electronics hidden in smoke detectors, clocks, and decorations. WiFi scanning detects wireless cameras, while infrared mode spots night-vision lenses in dark rooms.

Find hidden cameras by combining physical inspection with our detection technology. Look for tiny lenses, unusual wiring, or objects that seem out of place. Use the magnetic field scanner to detect electronic signatures in smoke detectors, mirrors, and electrical devices. Scan the local WiFi network for suspicious streaming devices. Turn off lights and use infrared mode to spot night-vision cameras.

Hidden cameras can be detected through their electronic emissions. Every camera contains motors, sensors, and transmitters that create detectable signatures. Our app identifies these signatures using magnetic field analysis, infrared detection, and network scanning. Even well-hidden cameras in smoke detectors, picture frames, or clock radios reveal themselves through the magnetic activity they generate.
