Found out that if my doorbell 2 is install within 12" to 18" from any wall the night vision becomes compromised (display is dark and viewing distance very short). Apparently the wall reflects light (overexposure). I tried holding the doorbell at approx a 50 degrees angle. It didn’t make any difference. I took the doorbell indoors at night and turned off the lights. It will only function properly if the doorbell is 12" to 18" away from any wall regardless if the doorbell is angled.
Anyone had this same problem? Any suggestions. Is this doorbell poorly designed or is this doorbell defective?
