Upon the real-time play, users should select a frame refresh rate per second. If the rate is high, the
image will become smooth. On the other hand, if the rate is low, the image will not be natural but it
can reduce a network load.
Bit-rate control
Variable bit rate (VBR) : Variable bit rate is increases when motion is detected and decreases when
no motion present, this is more efficient for the network. The default setting is VBR.
Constant bit rate (CBR) : Using a constant bit rate (CBR) may guarantee a stable play.
However, if a large amount of data is not required; this will place unnecessary traffic on the network.
Profile
SP (Simple Profile) is available up to the CIF resolution and 384kbit/s.
ASP (Advanced Simple Profile) is available up to the 4CIF resolution and 8000kbit/s.
GOV size
The GOV (Group Of Video) setting relates to the number / interval between reference frames (e.g.
full frame images). For example if set to 30 (Default) it will take one full reference frame followed by
29, frames which only record the changes to the reference on.
It is recommended that this setting is not altered.
