LED and LCD

Infrared LED Setting

On the Web

Set it up on the Intercom > Advanced interface.

• Mode:

  • Auto: Turn on the infrared LED automatically based on the minimum and maximum photoresistor value.

  • Always On: Enable the infrared LED.

  • Always Off: Disable the infrared LED.

  • Schedule: Turn on the infrared LED based on the schedule. Specify the Start Time and End Time when this option is selected.

• Photoresistor Setting: Set the minimum and maximum photoresistor value to automatically control the ON-OFF of the LED fill light. If the photoresistor value is less than the minimum threshold, turn off the fill light. If the photoresistor value is greater than the maximum threshold, turn on the fill light.

On the Device

Set it up on the Setting > LED screen.

• LED Type:

  • Auto: Turn on the infrared LED automatically based on the minimum and maximum photoresistor value.

  • On: Enable the infrared LED.

  • Off: Disable the infrared LED.

  • Schedule: Turn on the infrared LED based on the schedule. Specify the Start Time and End Time when this option is selected.

• Threshold: The current light intensity indicated by the photo-resistor value. The higher photo-resistor values correspond conversely to the lower light intensity and vice versa. The default photo-resistor value (Threshold) is 33. You can tap the icon   several times to obtain the actual photo-resistor value in a specific environment (the value fluctuation is about 5), and the value is the basis of configuring the minimum and maximum photo-resistor values.

• Min/Max Photoresistor: Set the minimum and maximum photoresistor value to automatically control the ON-OFF of the LED fill light. The default value is 900 and 1800. If the photoresistor value is less than the minimum threshold, turn off the fill light. If the photoresistor value is greater than the maximum threshold, turn on the fill light.

Card Reader LED Control

You can enable or disable the LED lighting on the card reader area. You can also set a specific time to turn on the light.

Set it up on the Intercom > LED Setting interface.

Screen Backlight Brightness

Set it up on the Intercom > Advanced > LCD interface.

• Backlight Mode:  

  • Manual: Set the backlight brightness value manually.

  • Auto: The screen backlight brightness will be adjusted automatically.

Note

The backlight brightness has two automatic modes, Day and Night. They are determined by the photoresistor.

• If the current value is between the minimum and maximum photoresistor, the device is in Day mode.

• If the current value is higher than the maximum photoresistor, the device is in Night mode.

• Backlight (Day): Select the brightness value from 2-255. The default value is 200. The larger the value, the brighter the screen.

• Backlight (Day) Standby: Adjust the backlight for the screensaver in the daytime with the value ranging from 2-255.

• Backlight (Night): Select the brightness value from 2-255. The default value is 200. The larger the value, the brighter the screen.

• Backlight (Night) Standby: Adjust the backlight for the screensaver in the nighttime with the value ranging from 2-255.

• Deep Sleep Enable: It decides whether the door phone enters deep sleep mode when idle. (Deep sleep means the device screen will be dark).

• Deep Sleep Interval: The time from the screensaver to enter deep sleep. The interval ranges from 5 to 30 minutes.

You can also set up the LCD backlight on the Setting > LCD Backlight screen.

White Light Setting

Set it up on the web Intercom > Advanced > White Light interface.

• Mode: Select Auto or OFF. If you select Auto, then the white light will turn on for 10 seconds within three conditions - staying home page; the photosensitive detection, and the IR detection are triggered.

QR Code White Light

The QR code white light is used for better scanning QR codes in a dark environment.

Set it up on the Intercom > Advanced > QR Code White Light web interface.

• Mode: Select Auto or OFF. If you select Auto then the white light will turn on for 10 seconds within two conditions - staying Temp Key page; the photosensitive detection is triggered.

• Exposure Mode: Select Auto or Manual. If you select Auto, then the white light will be changed along with the exposure grain changes due to ambient environment changes.
