IMPORTANT: When ‘Filter by Turbo mode’ as been selected; all High LAN options will be
auto-congured to match the prole record settings allowing for maximum record
performance. High LAN will no longer be available for conguration of local
analogue cameras or third party IP cameras. Select the Turbo Profs (red) option
to view Turbo mode Prole 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 gure entered will be the size of the JPEG
transmitted (in Kbytes). For MPEG4 the gure will be the bit rate
allocated. A higher rate will provide better quality picture display.
JPEG le sizes can be congured 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 sufcient. On MPEG
transmission, increasing the pictures sent will also reduce the
quality of the images (as more images are transmitted for the
dened 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
Ration option.
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 ration of I Frames recorded between each P Frame
.
Note: An MPEG I-frame is considerably larger than a P-frame. Therefore the higher the IP
ratio, the higher the disk space required to store recorded images.
