For example, settings relating to triggering functionality, time lapse functionality, image resolution, motion sensor sensitivity, flash intensity, and other camera functions can be altered. The settings can be altered based on environmental conditions such as weather and ambient noise. The settings can also be altered based on trail camera conditions such as available battery capacity or image storage capacity.
