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 to let IR light into the sensor for low light
sensitivity�
■ Auto
The Network Camera automatically removes the filter by judging the level of ambient light.
■ 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 the IR cut filter at all times for the sensor to accept
the infrared light, thus helps improve low light sensitivity.
■ 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�
Light sensor sensitivity
Select Low, Normal, or High for the light sensor sensibility.
Disable IR LED
If you don’t want to use IR illuminators, you can select this option to turn off.
Audio settings
Mute: Select this option to disable audio transmission from the Network Camera to all clients� Note
that if mute mode is turned on, no audio data will be transmitted to all clients even though the audio
transmission is enabled in the Client Settings page. In that case, the following message is displayed.
External microphone input: Select the gain of the external audio input according to ambient conditions.
Adjust the gain from +21 db (most sensitive) ~ -33 db (least sensitive)�
Audio type: Select audio codec AAC or GSM-AMR and the bit rate�
■ AAC targets at performing good sound quality at the cost of higher bandwidth consumption. The bit
rates are selectable at the following rates: 16Kbps, 32Kbps, 48Kbps, 64Kbps, 96Kbps and 128Kbps.
■ GSM-ARM is designed to optimize speech quality and requires less bandwidth. The bit rates are
selectable at the following rates: 4.75Kbps, 5.15Kbps, 5.90Kbps, 6.7Kbps, 7.4Kbps, 7.95Kbps,
10�2Kbps and 12�2Kbps�
