Exposure level: You can manually set up the Exposure level, which ranges from 1 to 8� The default value
is 4�
AGC (Auto Gain Control) : Automatic Gain Control, an electronic circuit which amplifies the video signal
when the signal strength falls below a given value due to the lack of light� You can manually set up the
AGC level (2X, 4X, or 8X)� The default value is 4X�
Enable auto iris: Select it to enable the auto iris function�
Enable WDR (Wide Dynamic Range): Select it to enable the WDR function� This Network Camera with
WDR feature can cope with very challenging lighting conditions� It is capable of capturing both of the dark
part and bright part of a target and combining the differences into a scene to generate a highly realistic
image as the human eyes can see� Note that if you select this function, Exposure level and AGC function
will be disabled�
Switch to B/W in night mode: Select it to enable the Network Camera to automatically switch to B/W in
night mode�
IR cut filter : With a removable IR-cut filter and built-in IR illuminators, up to 15m, this Network Camera can
automatically remove the filter and turn on the IR illuminators during the nighttime to accept IR illumination
for low light sensitivity�
■ Auto
The Network Camera automatically removes the filter by judging the level of ambient light.
■ Schedule mode
The Network Camera switches between day mode and night mode based on specified schedule�
Enter the starting time and ending time for the day mode� Note that the time format is [hh:mm] and is
expressed in 24-hour clock time� By default, the starting time and ending time of day mode are set to
07:00 and 18:00�
■ Day mode
In day mode, the Network Camera switches on the IR cut filter at all times to block the infrared light
from reaching the sensor so that the colors will not be distorted�
■ Night mode
In night mode, the Network Camera switches off (remove) the IR cut filter to allow the infrared light to
pass through� This improves the sensitivity of the Network Camera in low-light conditions�
You can click Preview to fine-tune the image, or click Restore to recall the original settings without
incorporating the changes� When completed with the settings on this page, click Save to enable the
settings and click Close to exit the page�
Video quality settings for stream 1 / stream 2: You can set up two seperate streams for the Network
Camera for different viewing devices. For example, set the Network Camera to a smaller frame size and
a lower bit rate for remote viewing on mobile phones. Or, set the Network Camera to a larger video size
and a higher bit rate for live viewing on web browsers�
■ Mode
This Network Camera offers two choices of video compression standards for real-time viewing: MPEG-4
and MJPEG�
If MPEG-4 is selected, it is streamed in RTSP protocol� There are four dependent parameters provided
in MPEG-4 mode for video performance adjustment.
