I have a mix of cameras—some v2s, a v3, a v4, a Cam Pan, and a doorbell. Did Wyze [degrade] the v2 for some reason? Because now the image is all grainy. The v3, v4, Pan and doorbell are all the same as before.
Tried both Apple and Android—same graininess on both.
ETA: the grainy cams were all previously updated to the last-available firmware.
Manually flash the cameras back an older camera firmware version. Wyze has v2 firmware available going back to 2023. You could see if older firmware will give you back the clarity you had.
