Read full description

Hidden Camera Detector provides five scanning tools to help you look for signs of potential hidden cameras and suspicious devices. Whether staying in a hotel, Airbnb, hostel, vacation rental, or shared space, this hidden camera finder and detector camera app can help give you extra awareness. Designed for travelers, families, and privacy-conscious users who want practical tools to scan rooms for possible surveillance risks. LENS DETECTION AND GLINT FINDER The lens detector uses your flashlight and camera to help reveal possible reflections from a camera lens. Use the glint finder to scan vents, clocks, smoke detectors, chargers, mirrors, and shelves where a hidden cam could be concealed. INFRARED CAMERA AND IR DETECTOR Some hidden cameras use night vision IR LEDs that may emit a faint infrared glow. The Hidden Camera IR Detector mode can help reveal this potential glow through your phone's camera. This infrared camera scan may help spot possible night vision cameras not visible to the naked eye. SPY CAMERA SCANNER AND WIFI DETECTOR Use the network scanner to review devices on the same Wi-Fi connection. The wifi detector checks for signatures that may resemble IP cameras or surveillance camera services. This wifi security scanner and camera finder can help spot possible spy cameras or nanny cam devices on the local network. BLUETOOTH SCANNER AND BLE SCANNER Scan for nearby Bluetooth devices and review which may warrant closer inspection. The bluetooth scanner lists BLE devices and may flag hardware associated with cameras or trackers. Use the BLE scanner alongside lens and IR results. May also help as an airtag detector, airtag scanner, and tracker detector for possible nearby tracking devices. RF DETECTOR AND SIGNAL DETECTOR Your phone's magnetometer and magnetic sensor can help reveal possible electromagnetic anomalies. Use the rf detector, rf scanner, and signal detector to check for potential hidden electronic devices. The rf signal detector, rf finder, and radio frequency detector features provide an anti spy and antispy scanning layer for possible wiretap detector and phone tapping detector scenarios. BUG DETECTOR AND HIDDEN MICROPHONE DETECTOR The bug detector can help look for signs of possible hidden microphones. The hidden microphone detector and hidden mic detector use RF scanning and Bluetooth detection to flag potential audio devices. This bug detector scanner, spy app detector, spyware detector, and gps bug detector may provide additional privacy protection. HIDDEN DEVICE DETECTOR AND TRACKING DEVICE DETECTOR Scan for possible hidden devices such as GPS trackers and covert recording hardware. The tracking device detector checks for Bluetooth signals from tracking tags. Combined with capture detection and motion detector features, this hidden app detector can help provide a broader sweep. The hidden eye mode may help visualize electromagnetic anomalies. PRIVACY SCANNER AND SECURITY SCANNER Run a privacy scan using all five modes. This privacy scanner, security scanner, and safe finder combination can provide a thorough anti-spy scan. Each safety scanner mode works independently or combined. Spyware detection, camera blocker alerts, and spybuster capabilities may help make this a complete counter-surveillance tool. WHEN TO USE IT Before settling into a hotel room, Airbnb, hostel, or vacation rental. When renting offices, studios, or co-working spaces. Anytime you want to check a room for peace of mind. PRIVATE BY DESIGN No account required. No data collection. All analysis runs on your device. This app assists with identifying potential risks and cannot guarantee detection of all hidden cameras. Results are indicators, not proof. Download Hidden Camera Detector Tool, your spyfinder, anti-spy scan tool, and hidden camera scanner for safer travel.

Sentra AI

Read full description

Sentra AI turns your existing security cameras into a real-time alert channel you can trust. Whether you are watching over your home, your shop, or a business site, you get told when something actually happens. Most camera systems flood you with motion alerts, and almost none of them matter. Sentra AI verifies detections before they reach you, so the notifications you get represent real events, not wind, shadows, or passing headlights. WHAT YOU GET Real-time verified alerts A push notification the moment a verified event is detected on one of your cameras, with a preview image and a short description, so you know what happened before you even open the app. Full event details Open any alert to see the captured image, which camera it came from, the exact time, and what was detected. Built-in media viewer View event images and clips full screen inside the app. Camera and alert control Choose which cameras you watch, which detection types matter to you, and set schedules or mute windows so you are not alerted when you do not want to be. Multiple users per account Add several people to one account so alerts reach everyone who needs to see them: family members, staff, or whoever is on call. WhatsApp alerts Optionally link a phone number to receive alerts on WhatsApp as well. Six languages with full right-to-left support English, Hebrew, German, Spanish, French, and Portuguese. GETTING STARTED Sentra AI works with connected NVR and camera systems. An account is required. Contact us through the support link on this page to find out about availability for your setup.
