Free Apps to Find Hidden Cameras on Your Phone — Android and iPhone [2026]

The concern about hidden cameras in private spaces is increasingly common among travelers, renters, and anyone who values their privacy.

Above you will find popular tools that help detect hidden cameras and protect your privacy in hotels, Airbnbs, changing rooms, and other spaces. They make it easy to scan your surroundings quickly and efficiently.

Below, we explore a list of free apps that promise to help you find hidden cameras using your phone, along with a detailed step-by-step guide on how to use each one.

1. Hidden Camera Detector – RF & IR

Hidden Camera Detector is one of the most popular apps that claims to identify hidden surveillance devices nearby. The app features a clean and intuitive interface, but requires access to your phone's sensors and camera. Here is how to use it:

Step-by-step guide for using Hidden Camera Detector:

1. Download the app: Visit the Google Play Store or the App Store and download Hidden Camera Detector – RF & IR.
2. Log in or create an account: After opening the app, you may be prompted to register or simply proceed as a guest, depending on the version you download.
3. Grant the necessary permissions: The app will request access to your phone's camera, flashlight, and sensors. Allow these permissions so the app can function correctly.
4. Run the detection scan: Go to the main dashboard and select “Start Scan.” The app will use your camera to detect infrared light emitted by hidden devices and alert you if anything suspicious is found.
5. Review the results: Once the scan is complete, the app will display a list of potential threats detected in the area. Move your phone slowly around the room for the most accurate results.

Although Hidden Camera Detector has many positive reviews, it is important to remember that no app can guarantee 100% accuracy in detecting every type of hidden device. Use it as a helpful first step, not a definitive solution.

2. Glint Finder – Camera Detector

Glint Finder is another widely used app for locating hidden cameras by identifying the reflective glint of a camera lens. It offers a straightforward set of features and is free to download, with premium options for additional functionality.

Step-by-step guide for using Glint Finder:

1. Download and install: The first step is to download the app from your device's store. It is available for both Android and iPhone.
2. Open the camera mode: Glint Finder does not require a social media login. Simply open the app and allow access to your phone's camera.
3. Enable the flashlight feature: The app uses your phone's flashlight to help illuminate the room and make camera lenses reflect light, making them easier to spot.
4. Scan the room slowly: Move your phone across the area in a slow, methodical pattern, paying close attention to smoke detectors, clocks, vents, and any unusual objects.
5. Identify suspicious glints: If a bright reflection or glint appears on your screen, stop and examine that area more closely. This could indicate a hidden lens.
6. Document and report: If you find a suspicious device, take a screenshot for documentation and report it to the appropriate authorities or property management.

While Glint Finder is quite useful for a quick visual sweep, the accuracy of the lens detection depends heavily on lighting conditions and the type of camera being used. Use it primarily as a visual screening tool.

3. DontSpy 2 – Detector

DontSpy 2 is an app that promises to detect hidden cameras and bugs by monitoring electromagnetic field (EMF) signals in the environment. It is available for free, making it accessible for anyone concerned about their privacy.

Step-by-step guide for using DontSpy 2:

1. Download the app: DontSpy 2 is available for iOS devices. Search for it in the App Store and install it on your iPhone.
2. Open the EMF scanner: After launching the app, you will be taken directly to the EMF detection screen. No login is required.
3. Grant sensor access: The app will request permission to use your phone's built-in magnetometer. Allow this so the detector can read electromagnetic signals accurately.
4. Scan the room: Hold your phone and walk slowly around the space. The app's meter will spike when it detects unusual electromagnetic activity, which may indicate the presence of a hidden transmitting device.
5. Investigate spikes: When the app registers a significant reading, investigate that area carefully. Pay close attention to furniture, outlets, and decorative items.

DontSpy 2 can be a useful addition to your privacy toolkit, but keep in mind that many everyday electronics can also trigger EMF readings. Use it alongside other detection methods for better accuracy.

4. Network Scanner – Hidden Device Finder

Network Scanner is a tool that detects hidden cameras connected to the same Wi-Fi network as your phone, making it particularly effective in hotel rooms and rental properties with shared internet connections.

Step-by-step guide for using Network Scanner:

1. Install the app: Network Scanner is available on both the Google Play Store and App Store. Download and open it on your device.
2. Connect to the local Wi-Fi: Make sure your phone is connected to the same Wi-Fi network as the space you want to check. This is essential for the app to work.
3. Allow network access: The app will request permission to scan the local network. Grant this access so it can identify all devices currently connected.
4. View connected devices: The app will generate a full list of every device on the network, including smart TVs, routers, phones, and any potentially hidden cameras streaming footage online.
5. Identify unknown devices: Look for unfamiliar device names or manufacturers in the list. Unknown or suspicious entries could indicate a hidden camera connected to the network.
6. Take action: If you find a suspicious device, disconnect from that network immediately and report your findings to the relevant authorities or the property host.

Network Scanner is considered one of the most effective tools for finding Wi-Fi-connected hidden cameras. However, it will not detect cameras that record locally without a network connection, so combining it with other methods is always recommended.

5. Fing – Network Tools

Fing is a comprehensive network scanner that goes beyond simple device detection, offering advanced tools for monitoring network activity and identifying connected devices that may include hidden surveillance equipment.

Step-by-step guide for using Fing:

1. Download the app: Fing is available for both Android and iOS. It is free to download and use, with a premium subscription for advanced features.
2. Create a free account: After installing, you will be prompted to create a free Fing account. This allows you to save and compare scans over time.
3. Connect to the target Wi-Fi: Join the Wi-Fi network of the space you want to check, then open the Fing app.
4. Run a network scan: Tap “Scan for Devices” on the home screen. Fing will quickly identify all devices connected to the local network, including their manufacturer, IP address, and device type.
5. Analyze the results: Review the list carefully. Look for devices from camera manufacturers such as Hikvision, Dahua, Axis, or any unknown device that does not match the expected electronics in the space.
6. Use the Fing security tools: The app also offers a network security assessment that flags suspicious activity, unauthorized connections, and potential vulnerabilities.

Remember that apps like Fing are powerful but work best when combined with physical inspection techniques, such as using a flashlight to check for reflective camera lenses and an RF detector to find wireless transmitters. A layered approach to privacy protection will always deliver the most reliable results.
