IR lights configurations

1. Setup from website:


Go to Intercom - Advanced to configure.

Photoresistor: The setting is for night vision, when the surrounding of R2X is very dark, infrared LED will turn on and R2X will turn to night mode.

Photoresistor value relates to light intensity and larger value means that light intensity is smaller. Users can configure the upper and lower bound and when photoresistor value is larger than upper bound, infrared LED will turn on. As contrast, when photoresistor value is smaller than lower bound, infrared LED will turn off and device turns to normal mode.

2. Setup from device:


For devices with single button E21/ R20/ R23/ R26 and devices with multiple numeric keyboard R27: N/A

For devices with touch screen - R29: Go to LED interface to configure.

Led Type: It can supports three modes - OFF, ON, AUTO. If setup the LED type as auto, click Threshold button to sense the intensity of the current environment.

Threshold: Click the Threshold key, it will automatic show the current intensity or user can setup the value manually. Once the environment intensity is darker than the predefined threshold value, LED will be up.

Min/Max photoresistor: Photoresistor value relates to light intensity and larger value mean that light intensity is smaller. When photoresistor value is greater than max value, LED will turn on. In contrast, when photoresistor value is less than min value, infrared LED will turn off and the device turns to normal mode.
