All trigger pixels
A map of all the pixels which triggered the camera's motion sensor over the duration of the object's appearance.
Difference frame
This frame indicates why the camera thought this object was interesting. It shows the difference between the video frame where the object appeared and the one before. White areas have brightened; dark areas have darkened.
Excluded pixels
This is a map of pixels within the frame which were being ignored owing to too much past variability. They may be foreground objects which are often illuminated by car headlights, for example. Only white pixels are ignored; different shades of grey indicate how much each pixel has varied in the past.
Trigger map
This map indicates why the camera thought this object was interesting. Grey spots indicate areas which had recently brightened by an unusual amount. White spots indicate areas large enough to trigger the camera's motion sensor.
Maximum brightness
This image shows the maximum brightness of each part of the image over the course of the object's appearance. This is usually the image that shows the object most clearly.
Previous frame
