Turning off the feature of motion detection. The SD cards with limited storage capacity, these features stop recording in case of undetected motions in front of the camera. As soon as the movement will be detected it will start recording again. For larger capacity SD cards, this motion detection feature is not a requirement. Some other reasons for stopped recording also include full memory card, machine error or wrong machine setting. For this purpose, there is a need to format SD cards, and if not so then change the memory card.
