ideas, but the first thing that inspired is the idea of whether it can be used for live cameras that can be remotely monitored and watched by making use of the smartphone camera function and Childmmunication function.As expected, looking at the app store, it seems that there are many apps that can be used for such purposes.On the other hand, a live camera, if it is misused, will make a

that the settings are very easy to understand, let's start setting and installing smartphones used as live cameras.Once you have completed the required settings in the application, just take the power and fix it.In the camera settings, there are items such as the selection of the lens (an out camera and in -camera can be selected) and whether to use the audio input.Even if you log in with a Google

camera.In the free version of Alfred Camera, ads are displayed on this list screen and individual viewer screens, but you can hide ads by upgrading them to a paid version.A dynamic detection function is recommended as a convenient function.If this is turned on, an automatic recording will be performed when the motion detects on the camera side, and the viewer will be notified and the video will be

beautiful images, and depending on the model, there are cases where the application goes down.rice field.So, if you want to upgrade to a paid version, it would be better to first confirm that the free
