Sensitivity: The manuals indicate this setting is based on the ambient temperature the camera will be in. Does this also affect what it takes to trigger an event? I have a camera set up in my yard and I have to get within 20ft of it (directly in front of the camera) for it to take a photo. It is set to Normal. The camera position is always in the shade. Will changing this setting to Low or High affect the distance for triggering an event?
