Installation Guide
IMPORTANT: When ‘Filter by Turbo mode’ as been selected; all High LAN options will be auto-
configured to match the profile record settings allowing for maximum record
performance. High LAN will no longer be available for configuration of local analogue
cameras or third party IP cameras. Select the Turbo Profs (red) option to view Turbo
mode Profile Record/Transmission settings.
Comp Settings can be established for JPEG and MPEG compression.
Res For MPEG and JPEG transmission, select image resolution settings
(4CIF, 2CIF, CIF or QCIF).
Size_rate For JPEG, the figure entered will be the size of the JPEG transmitted
(in Kbytes). For MPEG4 the figure will be the bit rate allocated. A higher
rate will provide better quality picture display. JPEG file sizes can be
configured in the range of 5-45Kbytes and MPEG bit rates in the range
of 45-2500Kbits/second.
PPS This shows the number of pictures transmitted per second. For JPEG,
the actual images transmitted will depend on the bandwith of the link,
increasing the pictures sent per millisecond may introduce time lag
if bandwith is not sufficient. On MPEG transmission, increasing the
pictures sent will also reduce the quality of the images (as more images
are transmitted for the defined bit rate).
MPEG Type Select whether transmitted MPEG4 images are sent as RAW data or in
GOV (Group of Video) format. RAW mode transmits a single I frame
and then a sequence of P frames (until a change in transmission is
detected). GOV mode sends I and P frames in a standard format i.e. I
to P frame ratio as set by the I Frame Ratio option (below).
MPEG Quality The Quality of the MPEG data transmission can be set from CBR
(Constant Bit Rate) to High 32. A higher quality setting may result in a
lower transfer speed.
I Frame Ratio Select the number of I Frames recorded between each P Frame.
Note: An MPEG I-frame is considerably larger than a P-frame. The higher the IP ratio, the larger the
disk space required to store recorded images.
Turbo Prefs (Red) Select to open the Turbo Mode Profile Overview menu, refer to
Appendix J - Status Pages for more information.
