How can we turn off IR led of R29?

For IR light, you can go to Intercom-Advanced-LED for configuring. The greater the value is, the darker the environment is. When the current value of RXX is greater than the right value, like 500, the light will be turned on. When the light is switched on, if the current value of RXX is smaller than the left value, like 200, the light will be turned off.
