Yes, you can set it in the settings. If you want the camera to work only during a period of time, please set this monitoring period function to "ON", press the OK button to confirm, and then set the start and end time. For example, if the start time is set to 6:35 p.m. and the end time is set to 8:25 a.m., the camera will work from 6:35 p.m. of the current day to 8:25 a.m. of the next day. Outside this period, the camera will not trigger and will not take photos/videos.
