I’ve been using Wyze Cams for years, mostly Wyze Cam V3s. Recently I tried the Wyze Cam V4, and have had 2 fail in only 1.5 years, whereas I have V3s that have lasted over 5 years.
Mine is at about a year, so far no issues. How did they fail? How are they mounted? Is there drip loop in the power cord at the back of the camera to help prevent water infiltration? What troubleshooting have you done (i.e. different power adapter, factory reset, etc)? Need more info.
