As opposed to iZone, the “EcoZone” can swiftly identify dynamic motion
that occurred within a scene
and retain its details with clear quality, whereas the rest areas, e.g., static background, will have a
higher compression level, resulting in economically decreasing bandwidth on less important things
but keeping the dynamic motion details for future forensic purpose. The intensity for EcoZone can be
defined by the “Level” dropdown menu.
High level means higher image quality and lower
compression in the Zone.
EcoFrame
Under Mode, select EcoFrame or E EcoFrame. By enabling the proprietary EcoFrame
function, the overall bitrate, i.e., bandwidth utilization, will be reduced even further. When less motion
occurs within a scene, e.g., in a storeroom, I-frame number, which is needed when motion is in a
scene, will be drastically reduced by EcoFrame activation. Based on divergent complexity of scenes
and motion occurred, a large amount of bandwidth saving can be achieved to deliver a compact yet
valuable performance on bandwidth utilization. Note that it is necessary to enable both EcoZone &
EcoFrame func
tions simultaneously by selecting the option “E EcoFrame
,
” since EcoFrame is
an enhancing technology that is based on EcoZone to promote the overall large scale efficiency by a.
High level means higher image quality and lower compression in the Zone.
Notes
Due to the attribute of dynamic bitrate management, “Rate Control” options (CBR,
CVBR and VBR) under Encode page are NOT
available when “EcoZone” function is
activated.
Due to the dynamic frame & bitrate adjustments, both “Rate Control” & “GOP” options
under Encode page are NOT
available when “E EcoFrame” function is
enabled.
Dynamic 3DNR
While 3DNR allows user to adjust noise reduction level manually, dynamic 3DNR dynamically and
automatically adjusts to the best noise reduction level according to the amount of noise on the image.
Lux level change is what triggers changes in noise reduction level for dynamic 3DNR. Higher lux
activates smaller noise reduction level.
Be aware that using Dynamic 3DNR in a scene that contains motion may result in blurred image.
When Dynamic 3DNR function is “O
n
” the 3DNR function under Image will become unavailable.
