Item 2: determines the type of user interface. "IR Control" uses the remote controller
to access the LE/LE-HC Series DVR and mouse mode (or GUI mode), which uses
the mouse (and an optional keyboard) to control the LE/LE-HC Series DVR.

q) Algorithm Setting

The video compression algorithm
can be set to MPEG4, H.263,
JPEG or M-JPEG. H.263 is a
compression standard similar to MPEG4 and will give
superior compression when there is little movement in camera fields of view. JPEG is a good
standard but is bettered by M-JPEG or MPEG4 where there is more motion in the video. In
instances where there is very low movement, H.263 or JPEG may provide better compression.
MPEG4 or M-JPEG are best if the resolution of the images is 640X480. Each camera can be
independently set to either 320x240 or 640x480 pixel resolution (dimension) in the Video sub-
menu of System Setup.
*Please Note: The only compression format available on the LE-HC is MPEG4.

r) NTP Setup

Network Time Protocol (NTP) allows the DVR to adjust its date/time clock to a world standard time
clock by accessing a special server on the Internet. A default server is provided (but can be
changed). A test and save is also provided.
