My sister’s son-in-law mounted a WYZE motion sensor over her house entryway. The sensor was picking up too much peripheral motion. He made a shield by cutting down a toilet paper core to 1.5” and painted it to match entryway color, to make it less prominent. This paper core fit very snuggly over the sensor; no adhesive needed. The core came from Costco Kirkland brand toilet paper. Some other brands do not work so well.
