It’s most definitely not a WiFi issue. The only question remains is did Wyze sacrifice the microphone quality to increase the image quality to maintain the same price point or is it simply a software issue that can be fixed by firmware.
I’ve watched now at least 20 reviews of the v3 on Youtube and they all exhibit the same static sound issue. I’ve also noticed in the reviews that on the v3 that the sound was going in and out for them which isn’t good. One reviewer had all the wyze cameras available and compared them one by one and the v3 seemed to have the worst audio in comparison, but had the best video.
Either way, if the static doesn’t bother you, then you’re getting an awesome camera at a extremely decent price. If, like me, the sound quality is a deal breaker, I’ll wait and see if it gets fixed at some point.
