Most hidden cameras with mobile apps are designed to be compatible with both iOS and Android devices, such as smartphones and tablets. Some models may also work with other devices that have a Wi-Fi or Bluetooth connection, such as laptops or desktop computers. It is important to check the specifications of the camera and the mobile app to ensure compatibility before purchasing.
Additionally, some hidden cameras may require a certain operating system or version to work properly with the mobile app. For example, a spy camera with a mobile app may require an iOS device running on version 9.0 or higher, or an Android device running on version 4.4 or higher. It is recommended to always check the compatibility requirements before purchasing to avoid any issues with the app or the camera.
