be displayed if VBR is chosen from the Bit Rate Type drop down selection. The
higher the quality set, the more bandwidth used and vice versa. The quality setting
are Lowest, Lower, Low, Medium (default), High, and Highest.
BIT RATE (KB/S)
The BIT RATE (KB/S) option is used to define the maximum amount of information
or detail, which is stored per unit of time of a recording. A higher bit rate will allow
a better image to be produced but will use more resources such as memory and
network bandwidth. The BIT RATE option will play a huge factor on the live feed
when viewing the IPcam-SD remotely over the internet. The higher the BIT RATE
setting the better quality of video you will see, however if you have a slow internet
connection and set the BIT RATE to a higher setting than the connection can handle
the feed will become sluggish. BIT RATE is only available if CBR is selected as the
Bit Rate Type. The bit rate ranging from 512 (default), 768, 896, 1280, 1536, and
2048Kb/s for the main stream and 144, 217, 289 (Default), 361, 434, and 578Kb/s for
extra stream.
FRAME INTERVAL
The FRAME INTERVAL (SEC) is the method used for better video steaming over the
internet. This method detects only the changes from within that given picture frame
and streaming only the changes in that frame making video transmission faster,
clearer image quality, and conserves the internet bandwidth. The system default is
set to 2 frame intervals per second.
VIDEO/AUDIO
The VIDEO/AUDIO option is used to enable (default, checked) and disable (un-
checked) audio or video for the selected stream type (Main, Extra).
NOTE:
The audio must be checked (system default) to listen in on the IP camera
from your CMS software. To listen in on the IP camera, check this option and then
right mouse click on the camera image of the GUI and then select Audio.
SNAPSHOT
The SNAPSHOT option allows you to setup Image Size, Image quality, and the
number of seconds/picture you want to send to your email when setting the
SNAPSHOT to manual.
STATIC CONFIGURATION OF
The STATIC CONFIGURATION OF is H.264 standard profiles which are consists of
different levels; baseline, main profile and high profile (system default). The baseline
offers I/P-Frames supporting progressive and CAVLC (Context-adaptive variable-
length coding). Set to main profile to achieve I/P/B-Frames supporting progressive
and interlaced, CAVLC or CABAC (Context-based adaptive binary arithmetic
coding) where baseline does not support for smoother encoding process. Set to
high profile (recommended, system default) for lossless video encoding, highest
efficiency.
COPY
The COPY button can be used to copy the current configuration on the screen to the
other cameras available through the CMS (when more than one camera is available).
PASTE
The PASTE button is used to paste the configuration settings that were copied to
the selected camera.
REFRESH
The REFRESH button discards the changes you made to the current settings and
sets them back to the way they were when the configuration window was first
opened.
