Hidden cameras with mobile apps typically require an internet connection to function properly. The mobile app is used to control the camera and view the live feed or recorded footage, and this requires a stable internet connection to transmit data from the camera to the app. Most cameras are able to function offline or without an internet connection, but the user would not be able to access the live feed or view recorded footage remotely using the mobile app.
In addition to requiring an internet connection, some hidden cameras with mobile apps may also require a specific type of internet connection, such as Wi-Fi or cellular data. It is important to check the camera’s specifications and compatibility with your internet connection before purchasing and setting up the camera.
