Poor Audio on playback

When we try to listen to the outside given our neighbors are playing very loud music and shooting the audio doesn't pick it up. Also, what we can hear is very noisy like wind blowing by. Can barely hear anything. The audio cracks and pops. I just installed these last weekend. 2 Door bells and 4 solar cameras. I don't want to waste the money if they don't work right. I have called AT&T to come out tomorrow and install a slightly faster wifi service as well as a wifi signal booster/ranger extender. I am hoping this helps. If this doesn't clear up what is the return policy on just the cameras. We will be keeping the doorbells.
