iStream
This is a groundbreaking technology that helps save network bandwidth efficiently while maintaining
the clear image quality for critical image details based on the 2 cutting-edge features. Click iStreams
to enable the features as follows:
Figure: iStream Settings

EcoZone
T he “EcoZone” can swiftly identify dynamic motions that occurred within a scene and retain its details
with clear quality, while the rest of the areas, e.g., static background, will have a higher compression
level, resulting in economically decreasing bandwidth on less important areas 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.

E EcoFrame
Under Mode, select 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., storeroom, I-frame number, which is needed when motion is in a scene, will be drastically
reduced by EcoFrame activation. Based on complexity of scenes and motions 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 functions
simultaneously by selecting the option “EcoZo ne + EcoFrame, ” since EcoFrame is an enhancing
technology that is based on EcoZone to promote the overall large-scale efficiency. The intensity for
E EcoFrame can be defined by the “Level” dropdown menu ; High level means higher image
quality and lower compression in the Zone.
Note

Due to the attribute of dynamic bi trate 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, bot h “Rate Control” & “GOP” options
under Encode page are NOT available when “E EcoFrame” function is
enabled.
