Recent cold weather ?
Mine is doing the same thing, will detect audio but its completely blind to any motion.
Tried resetting the base, the camera (battery pull) and nothing. Will only record manually.
Im so fed up with this arlo wireless camera crap, Ive started looking into the class action lawsuit against companies like arlos that continue to rip off customers. Their new system prices are unreal, never again. You are better off getting robbed and paying the home ins deductible.
Why isn't Arlo answering these questions? I am fed up as well with the Arlo camera system. Can't get any answers, ANYWHERE.
A mod did in the post before you however this a user to user forum so you should contact support below.
