Video image controls

Note These controls appear when you click the Right Arrow in the Video Control area.

Brightness slider	To control the brightness of the video image, drag the slider, or enter a value
	from 1 through 10 and press the Enter key. A higher value increases the
	brightness and a lower value decreases the brightness. For example, if the IP
	camera is facing a bright light and the video appears too dark, you can increase
	the brightness.
	The default value is 5.
Contrast slider	To control contrast of the video image, drag the slider, or enter a value from 1
	through 10 and press the Enter key. A higher value increases the contrast and
	a lower value decreases the contrast.
	The default value is 5.
Sharpness slider	To control the sharpness of the video from the IP camera, drag the slider, or
	enter a value from 1 through 100 and press the Enter key. A higher value
	increases the sharpness and a lower value decreases the sharpness.
	The default value is 50.
Saturation slider	To control the saturation of the video from the IP camera, drag the slider, or
	enter a value from 1 through 100 and press the Enter key. A higher value
	increases the saturation and a lower value decreases the saturation.
	High saturation provides a vivid, intense color for a video image. With less
	saturation, the video image appears more muted and gray.
	The default value is 50.
Restore button	Resets white balance, brightness, contrast, sharpness, saturation, and hue to
	their default values.
