Bitrate: This parameter corresponds to the speed of data transfer that the NVR will use to record video.
Recordings that are encoded at higher bitrates, will be of better quality. For cameras that monitor
medium to high traffic areas, increase the bitrate to add more detail to the camera's image. Just be aware
this will increase the bandwidth required. Increase the bitrate in small doses until you are satisfied with
the image quality.
Audio: If your camera has built-in microphone or external audio input device, you're able to record the
audio streaming together with the video streaming. Click the checkbox to disable or enable. Make sure
you have already enabled the Audio streaming in 5.2.1.2. Audio Encoding if you want to record the audio
streaming.
I Frame Interval: This configures the number of partial frames that occur between full frames (I-Frames)
in the video stream. For example, in a scene where a door opens and a person walks through, only the
movements of the door and the person are stored. The stationary background that occurs in the previous
partial frames are not encoded. As the I-Frame increases, the number of partial frames also increases.
Higher values are only recommended on networks with high reliability, otherwise leave the default
selection.
ETR: If your camera supports ETR function, it allows you to set independent video streaming for normal
and alarm triggered recording.
For example, you can decrease the frame rate and bitrate to reduce the recording file size in normal
recording, and increase the frame rate and bitrate to have clearer and more fluent camera images when
an alarm event occurs.
ERT available for mainstream only.
5.2.1.2 - Audio Encoding
If your camera has built-in microphone or external audio input device, you're able to activate the audio
stream, define the input/output volume, and select the audio encode type.
Enable: To turn on or turn off the audio streaming.
Output Volume: To choose the audio output volume
Input Volume: To choose the audio input volume
Type: To choose the audio encoding codec.
