Backlight Compensation
This lets you turn on or turn off backlight compensation and select the strength of the backlight compensa-
tion, which when enabled can make the subject appear clearer in the image when the backlight is too bright
or the subject is too dark. (Default: Disabled)
Flickerless
Here controls the flickerless mode: 60 (default) or 50 Hz.
Exposure Control
This allows you to control the exposure time of the camera, which affects how much light is exposed to the
sensor. Default: Auto mode. You can manually set the shutter speed within the range of 1/5s to 1/16000s to
suit your lighting conditions. In Auto mode, the gain level is automatically determined by the camera under
normal lighting condition. When [Auto] is selected and low environmental lighting is detected, the shutter
speed and gain level will be set as 1/30s and 7.5 respectively unless you have enabled the Low Light Behavior
option and manually specified exposure and gain value.
Low Light Behavior
Switching on the Low Light Behavior will produce better and clearer image when the camera detects low
environment lighting. When the Exposure Control is set as [manual], the Low Light Behavior control will be
dimmed and inaccessible. Here the default setting is [Off], and the shutter speed and gain level will be set as
1/30s and 7.5 by default on the condition that low environment lighting is detected. Switching on the low
light behavior allows you to manually set the shutter speed and gain level in the case of low environment
lighting. There are two adjustable parameters for low light behavior.
• Maximum Exposure - Adjust the shutter speed by selecting between “Disable” and “30 fps”. Lower frame
rate means longer exposure time, which allows more light to be captured by the image sensor. However if
there is fast motion in the scene, increased exposure time will result in motion blurs in the captured image.
Choosing [Disable] will use the default value of max. exposure and max. gain in low-light setting, which
are 30 fps and 7.5 respectively.
• Maximum Gain -
This allows you to adjust the gain level between 1 and 8.5 dB. Higher gain level increases
the brightness of the picture but also increases the noise in the picture.
Embed Text and Image
You can embed text and/or image at 4 different locations on the live screen. (Upper Left, Upper Right, Lower
Left, Lower Right). To embed an image, click on the Upload Image text link and choose a suitable image (limited
to JPEG/BMP, 100x30 pixels, 128KB.) To remove an embedded image, press the [Clear] button.
Flip Mode
Enabling this option will flip the image vertically, making the image appear rotated 180 degrees. Enable this
Audio Settings
Here you can choose to enable or disable the audio and also adjust the volume. The Stream-2 audio is only
available for adjustment when you turn on the 2nd Stream and check its 3GPP mode option under video set-
tings.
