[Exit Option]

 Auto Shutdown Windows: Closes Windows OS after exiting GV-System.

 Auto Restart Windows: Restarts Windows OS after exiting GV-System.

[Display]

 Enable DirectDraw Scale: Applies DirectDraw Scale to enhance image quality if your VGA card

supports it. For certain VGA cards, DirectDraw Scale can result in blurred images. To avoid the

image problem and remain DirectDraw Scale, change the image quality from High to Standard.

See Image Quality of DirectDraw Scale in System Tools later in this chapter.

 Enable De-interlace Render: Avoids interlace of the odd and even video lines. This feature

affects only single view mode with the resolution of 640 x 480 and 704 x 480. After enabling the

feature, you must restart the GV-System to apply it.

Note: The Enable Directdraw Scale and De-interlace Render features can greatly enhance image

quality. If your VGA card supports DirectX9, enable both settings.

Tip: To check the version of your DirectX, search for the file name dxdiag. Open the file and find the

related information.

[Video Record]

 Max Video Clip: Specifies the maximum time length of each recorded file (from 1 to 5 minutes). If

you select 5 Min, a 30-minute event will be chopped into six 5-minute event files; if you select 1

Min, a 30-minute event will be chopped into thirty 1-minute event files. To decide what to set up

here, consider how often you back up your event files, and how intensive the activity is in your

surveillance area. Smaller file size makes backup process faster.

 Post-Rec: Keeps on recording for a set period of time after motion stops.

 Pre-Rec: Records video for a set period of time before motion starts or an input device is

triggered. This feature allows you to choose RAM or HDD as a pre-recording buffer. The

difference between the two is that RAM can save smaller pre-record from 1 second to 1.5 minutes,

while the hard disk can save larger one from 1 minute to 45 minutes.
