Administrators should notice that the basic network settings including IP address,

subnet mask, default router and DNS servers will be cleared when the network interface

is switched to the other between Ethernet and modem.

Video and motion detection

Adjust image settings

"Time stamp" and "Text on image" will be enclosed in image for reference. The

timestamp is captured from date and time of Network Camera that is maintained by an

on-board real-time clock. "Color" setting is independent of the connected camera and

“B/W” option can speed up the encoder a little. “Default size” option here will be the

default size of video window when users first connect to Network Camera. “Default

quality” option here will be the default quality when users first connect to Network

Camera. To adjust image settings for best visual quality, press

and a

motion picture window will pop up for your reference. There are four fields including

"Brightness", "Contrast", "Hue" and "Saturation" for video compensation. Each field

has eleven levels ranged from -5 to +5. While adjusting, administrators can click on

to check prior to the setting in memory. If the adjustment is not good,

administrators can click on

to restore the original settings without change. After

configuration done, click on

to close this window. If parameters are changed

without saving, they will be used until the next system startup.

Configure motion detection

The channel can have its own settings of motion detection independently. The settings

including “Object size” and “Sensitivity” allow administrators fine tune to fit into the

environment. The “Object size” decides the space ratio of motioned objects over the

monitored screen. The “Sensitivity” sets the measurable difference between two

sequential images that would indicate motion. The larger object size and lower

sensitivity will make Network Camera ignore small variations in images. While the

motion amplitude of some object in the monitored screen is over the settings, a white M

in red background will indicate at the upper-right corner of the window.

Motion detection is provided as reference because it is very environment-dependent.

Especially working by the very sensitive settings, some triggered events may be

considered as false alarms though there is tiny difference happening indeed. It can be

affected by florescent light flashing, shadow shifting, and so on.
