Kahoot! Kids: 교육 어린이 게임

A smartphone can have the function of a drive recorder. You can always record with the front or rear camera, which is also effective for tilting. The focus can be kept constant, and the white balance is adjusted when passing through the tunnel.
In vibration detection mode, if a gyroscope sensor detects a vibration exceeding an arbitrary threshold, it will notify you by email. A snapshot of the previous and next videos will be attached to the email. The location information notification function sends location information by e-mail when a distance exceeding an arbitrary threshold is moved at regular time intervals. It is a powerful tool for parking monitoring of your car.
