(see Figure 6-4). Check this option for recording preview.
[Audio Setting]
Monitor Sensitivity:
Adjust the sensitivity of the audio that will be detected. The
higher the value, the more sensitive the system is to the surrounding sound.

Increase or decrease the gain of the microphone.

[Hardware compressed data control]
Hardware-compressed data from the video IP device, such as IP Camera, Video Server
and Compact DVR, can be transmitted directly to remote servers instead of being
compressed again on GV-System. The remote servers include Center V2, Control Center
and WebCam. This function is useful when many remote servers access GV-System at
one time. It can reduce the system load on GV-System, and provide more frame rates and
better image quality for each remote server.
Note:
It is highly recommended to enable this function on a LAN environment because it
requires a lot of bandwidth.
