Utilization series of smartphones that are no longer used
It's very easy to use.
First, fix the smartphone in the direction you want to shoot.
Click the start button.
Drag the virtual line to the desired position on the screen to set it.
If you try to make a beep across the virtual line, it is detected.
The sensitivity can be adjusted in 5 steps.
You can also darken the screen in the settings.
The recorded video can be viewed immediately by playback.
Also, you can save the video you want to keep by compressing it.
It also has a repeat function.
Repeat detection → detection → recording, and save the recorded video in the compressed data.
When the position is decided, tap the sensing start button.
