This is the time between when the camera finishes sending a motion-triggered photo or video and when it is allowed to take another one. When the camera is triggered by motion, it will take and send the photo or video, then it will wait for the specified Trigger Interval before it will take another motion-triggered photo or video. While the camera is sending, it cannot take another photo or video. The trigger interval starts after the camera has uploaded the latest photo or video. For example, if the camera takes 25 seconds to upload a photo and the trigger interval is set to 30 seconds, then the amount of time between photos is 55 seconds.
