Just remember that the bitrate is the amount of data transferred per second so a high
bitrate will produce a high quality image which requires a faster internet speed. A low
bitrate will produce a low quality image better for slower internet speeds.
Enabling Audio
You can enable or disable audio recording for each channel by ticking or unticking
the
Volume check box.
I Frame Interval
I Frames is a compression technique used to create smaller video files. It works by
taking one key frame called an I Frame which the recorder will then use as a
reference point. For each frame after the I Frame the recorder will only capture parts
of the image which have changed rather than capturing the entire image.
With the I Frame Interval you set how often a new I Frame is captured by setting the
number of frames between each I Frame. Setting the interval too low and the I Frame
will become ineffective as there is such a short time between each reference point.
On the other hand, if the interval is too high so much may have changed between the I
Frame and the current frame that the recorder is effectively capturing and entire new
image anyway.
As a rule of thumb we recommend setting the I Frame Interval at double the frame
rate so that a new I Frame is captured every 2 seconds.
For example if the frame rate is 12 frame per second (FPS) the I Frame Interval
would be set as 24 so that the recorder captures a new I Frame every 24 frames.
