IR cut lter

With a removable IR-cut lter and built-in IR illuminators effective up to 15m, this Network Camera can

automatically remove the lter and turn on the IR illuminators to let IR light into the sensor during low

light conditions�

■ Auto mode

The Network Camera automatically removes the lter by judging the level of ambient light.

■ Day mode

In day mode, the Network Camera switches on the IR cut lter 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 lter 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 a specied 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�

selectable from: 16Kbps, 32Kbps, 48Kbps, 64Kbps, 96Kbps, and 128Kbps�

■ GSM-ARM is designed to optimize speech quality and requires less bandwidth. The bit rates are

selectable from: 4�75Kbps, 5�15Kbps, 5�90Kbps, 6�7Kbps, 7�4Kbps, 7�95Kbps,10�2Kbps, and
