Scalable Frame Rate
Due to multi-browsers support, the performance of live view will vary according to the efficiency of
each browser and client device. Therefore
, the “Scalable Frame Rate” is introduced to help user
dynamically adjust to a desired frame rate per browser applied for smooth video display. The option
“Full” indicates a full frame rate display in response to the setting under “Encode” page, whereas “1/2”
& “1/4” mean that display frame rate will be reduced to
one half and one quarter, respectively. Turn
“ SVC-T ” on before using this function. Refer to “
SVC-T
” for further details. (Only available in ActiveX
mode.)
Note

Scalable Frame Rate is only available in ActiveX mode.
Live View Jitter Buffer Length
Live View Jitter Buffer Length determines when to transmit media packets for Live View display based
on packets it has collected, packets it is still waiting for and the timing required to playback the media.
Dragging the adjustable bar of “Live View Jitter Buffer Length” to a higher value lessens the negative
effect, namely choppy live video display, caused by transmission delay arising from network
congestion. However higher values also increase overall transmission latency.
Note

Live View Jitter Buffer Length is only available in ActiveX mode.
Video Analytics

Select a Video Analytics (VA) function from the dropdown menu. Make sure that the selected VA
function is enabled in “Video Analytics” section. When “Off” is selected, the camera is not performing
any VA function.

Draw Object Bounding: Check this box to allow camera to activate motion detection and draw an
area around the detected object. This function can be used only when a VA function is activated.
