„ Drop-down List: Select the desired camera for live preview
„ Preview dual stream record channel: The option is only available when the dual stream is set,
i.e. the cameras for live view and recording are configured differently (see Figure 1-120). 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.
„ Gain Control: Increase or decrease the gain of the microphone.
„ Wave Out: Enable this option to listen to live audio from the camera.
„ Rec Audio: Enable this option to activate the audio recording.
[Hardware compressed data control]
The hardware-compressed data from the video IP device, such as IP Camera, Video Server and
Compact DVR, will 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.
