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.
LED Indicator
This lets you control the LED indicator at the front of camera. Turn on the LED indicator, or turn it off in case
you don’t want people to notice the camera is working.
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
setting when you need to reposition your camera from standard position to ceiling mounting position.
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
settings.
