Infrared LED Setting
The infrared LED is applied in a dark environment in which a resident might not be able to
see a visitor clearly via the video from the door phone. If the infrared LED is turned on, the
door phone will turn to night mode so that you can have a clear view of the visitor. You can
set up it on the device web Intercom > LED Setting > LED Fill Light.
Parameter Set-up:
•
Mode: select infrared LED mode.
•
If you select Auto, then the infrared LED will be turned on automatically based
on the photoresistor setting below.
•
If you select Always On, then the infrared LED will stay on.
•
If you select Always Off, then the infrared LED will stay off.
•
If you select Schedule, then the infrared LED will be turned on based on the
photoresistor setting according to your schedule.
•
Photoresistor Setting: set the triggering points for disabling the infrared LED and
enabling the infrared LED. For example, if you set the triggering points at 1500-1600,
the infrared LED will be enabled when the photoresistor value gets higher than 1600
(the video image you see from the door phone will become black and white) and if
the value gets lower than 1500, then the infrared light will be disabled (the video
image you see will have color).
•
Start Time - End Time: set the infrared LED light start time and end time.
