As advertised, I had check the operation of the unit before I removed the the unit for 10 minutes and re-install my door bell pro back on(01-15-20). The unit seem a little bit warm. But nothing help! the door bell pro still has these problem. Upon close inspection, maybe It was NOT (IR) infrared issue?, maybe more of HDR issue?? Because due to IR light limited, the over exposure/wash out issue can NOT reach all the way to the top and all the way to the side, my video is completely washed out whole screen!!!
Sometime I feel like it know that I am looking at it, and I trying to find the problem, so the problem go way by it self right after I pull out my phone and load the app(to check on it). Hahaha very strange if you ask me.
This unit at this location was brought as a certified refurbished. One year warranty, so I will be contact ring customer service soon.
