File out is useful when using DOODS or other image processing system to show what exactly was detected. However, on the flip side ONLY a detection will update the output image.
When using this with a camera in many cases it would be nice to have a configuration option that outputs the original input image if there was no detection. This way a simple consistent image can be shown even if there are no detection within a scan interval. Also for troubleshooting when using the system to COUNT it would be nice if when it returned to 0 you could actually see that reflected in the output.
