Prole
This identies the prole that is being congured and can not be changed.
Description
It is possible to allocate a description to each of the proles to allow the Operator to easily identify the selected
prole, use information that is relevant to the settings.
Image size
This identies the pre-congured image size for the MPEG prole being congured and can not be edited.
MPEG Quality
NOTE: It is recommended that this setting be left at the default Constant Bit Rate. Selecting any other
setting is for specialist conguration and could result in high bit rate throughput which would
require high storage requirements or low quality recorded images and should be carefully
congured and tested.
Select the MPEG quality that will be associated with this prole, the options are:
Constant Bit Rate (default) Recommended. Sets the recording bit rate to a constant making the record
duration predictable.
High 02 - High 12 High quality settings providing high quality recorded images but would
also produce larger storage requirements.
Medium 13 - Medium 22 Medium quality images with average storage requirements.
Low 23 - Low 32 Lower quality images but reduces the data and therefore the storage
requirements.
MPEG Bitrate
This option is active when Constant Bit Rate is selected in the MPEG Quality option. Set the bit rate in Kbits/s,
this can be from 8Kbits/s to 8192Kbits/s.
Record Rate
This identies the record rate for the selected prole and can be from 01 PPS to 25PPS (30PPS NTSC).
I-frame Interval
MPEG recording uses a ‘reference’ frame at a designated interval, and then records the difference between that
frame and the next image. This reduces the amount of space required for storing video. The image can deterio-
rate if this interval is too great. The I-frame interval is the period between the ‘reference’ frames.
The Operator is able to determine how often the I frame will be recorded within the selected prole.
