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 during low
light conditions�
■ 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 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
infrared light, thus helping to improve low light sensitivity�
■ Schedule mode
The Network Camera switches between day mode and night mode based on specified schedule. Enter
the start and end time for day mode� Note that the time format is [hh:mm] and is expressed in 24-hour
clock time� By default, the start and end time of day mode are set to 07:00 and 18:00�
Light sensor sensitivity
Select Low, Normal, or High sensitivity for the light sensor�
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 even if audio transmission is enabled on the
Client Settings page� In that case, the following message is displayed:
Internal microphone input gain: Select the gain of the internal audio input according to ambient
conditions. Adjust the gain from +12 db (most sensitive) ~ -34.5 db (least sensitive).
External microphone input: Select the gain of the external audio input according to ambient conditions�
Adjust the gain from +20 db (most sensitive) or 0 db (least sensitive).
