3-7 Night Mode Control
The IP Cam is able to work both in day time and night time. There are some IR LEDs that
can let the IP camera see the objects in the night time. Users can adjust the numbers of the
IR LEDs according to the view sight distance during night mode to get the best night mode
vision. The night mode status is also displayed.
This night mode control page is to control when the time the IR LEDs will be on. There are
three ways to control the night mode ( IR LEDs ) :
1. Automatic day and night mode switch: the IP cam will automatically turn on the IR LEDs
when the night time is arrived or the environment is becoming dark. There is a light
sensor on the IP cam that is doing this light detection.
2. Scheduled time of night mode: the IP Cam can also be scheduled to turn on the IR
LEDs in a time range of each day.
3. Manual night mode control: the IP Cam can be manually forced to night mode( IR LEDs
on ) or day mode( IR LEDs off ).
In order to get better video color display during day time and night time, there is an ICR(IR
Cutter Remover) in the IP Cam. This ICR will be controlled automatically to filter out the
IR(Infrared) light during the day time and allow the IR light to pass during the night time.
This make sure the video color quality is excellent compared to other IP camera.
