Turbo Mode
Select to activate the Turbo mode function (see ‘What is Turbo mode?’
for a description of Turbo mode and its benefits).
Unset/Set/Override Normal
Shows the recording profile used by the camera if no Timed Schedules
are applied and the camera is operating under Normal (non Event)
conditions. Refer to ‘Schedule’ for further information.
Unset/Set/Override Event
Shows the recording quality that will be used by the camera during
an Alarm or Event. Note that Set and Override schedules will be used
only when Timed Schedules are applied. Refer to ‘Schedule’ for further
information.
Note: When Turbo mode is selected, there will be only ONE configurable Record Profile across ALL
cameras. The unit then matches the live transmission rate to the configured record rate. This
enables a ‘doubling’ of performance. Only the ‘Low’ and ‘Medium’ Live Transmission profiles
are available for configuration (Network Settings->Live Transmissions). Low and Medium
transmission settings are configurable to allow video streaming over low bandwith IP connections
and are limited to CIF for this purpose.
Note: Unset, Set and Override modes can be given more recognisable titles i.e. Day, Night, Weekend
via the Schedule menu (Record Settings->Schedule).
Comp
Select image compression format (MPEG, H264, JPEG).
Res
Select image resolution (QCIF, CIF, 2CIF or 4CIF).
Rate_kbps
If MPEG4 is selected, the figure entered here will be the bit rate
allocated. A higher bit rate will provide better quality. MPEG bit rates
can be entered within the range of 45-2500K bits/second.
IMPORTANT: The bit rate allocation here will be limited to a maximum rate (limit dependent on model).
For 8 and 16 channel units, the limit is 2048 per camera. For 32 channel units, the limit
is 1024 per camera.
Size
If JPEG is selected, the figure entered here will be the size of the JPEG
transmitted (in Kbytes). JPEG file sizes can be configured within the
range of 5-45Kbytes.
PPS
Select the number of pictures recorded per second.
GOP
If using MPEG4/H264 recording, select the number of images recorded
within a GOP (Group of Pictures). A GOP consists of an I-Frame
(keyframe) and following P frames.
Note: The GOP is also the rewind interval and stop interval for MPEG recording playback.
Note: An MPEG I-frame is considerably larger than a P-frame. Therefore the lower the GOP ratio, the
higher the disk space required to store recorded images.
Codec Load (Red)
Select to open the System->Status->About->Codec Loading page
Refresh (Purple)
Refreshes the information on the current page.
