I have checked app settings and color night vision is selected.
What happens is the unit will be in color night vision but if someone gets close enough to the doorbell, it sounds an audible click and switches out of color night vision, turning on the bank of red LED’s and it stays in black and white. The only way I can get it to return to color night vision is to drop power. That is the only way I have found to make it switch back to color night vision. If I do that, it switches to color night vision but that is only temporary until someone again steps in front of the doorbell camera and ir dtops back to black and white. And I can’t stay up all night dropping power.
I have verified the power at the doorbell is 24v. The transformer supplying the power is rated 24v 40va. I do not believe lack of power is not the issue. Status from the phone app shows 4107.0 mv. There is no internal mechanical chime connected. All power is straight through from the supply transformer to the doorbell.
What can I do at this point?
