An IP65 rating means a device or enclosure is fully protected against dust and protected against low-pressure water jets from any direction. It’s a common standard for applications needing protection from dust and moderate water exposure, but it’s not designed for submersion or high-pressure water.
That environment an IP65 rated device should withstand, Wyze has a 1 year limited IP65 rating.
If it fails under warranty only
By the way my V2’s with the add-on birdhouse enclosure never had the lens fail and lens is fully exposed with that type of enclosure.
