“Simple” and “Complex”
This DVR uses MPEG4 recording, which uses the previous image as a reference for
recording the next one. If there is little difference between images, the DVR uses the
size for a “simple” image; however, if there is constant change between the images, it
will use the size for a “complex” image. The times given in the following tables show the
absolute maximum and minimum for these sizes and should only be used as a
reference.
