Dear customer: Hi! This time-lapse camera takes photos or short videos at set time intervals and automatically combines them into a long video to record interesting things in your life. If you like to observe changes in animals, plants and the environment, such as the growth of plants and the blooming of flowers, you need to record something; the development of things, such as the process of building a house, the process of making handicraft, and so on. Hope our answers are helpful to you and wish you a happy life! Dsoon
