I just got KC120 as first indoor camera & its been couple of hours to set up and test. & ran into following issue

1) Watchin live footage, I hear constant sound like pouring sugar or samll bid in jar. 

2) most of clip when try to play  ( on androind phone in KASA app) it display error message  as  "Clip Unavliable -somethign went wrong while uploading form cam..."

3) Frequenlty freeze  footage while watching live

4) Not able to view footage  from google hub screen ( both linked to same wifi netwrok)

I tried follwoing stesp but no luck.

1) reset camera  by click  on reset button back side of camera and again connect

2) using app delete device from camera and connect again 

3) Change WIFI netwroks 2.4 ghz or 5ghz

Hardware version is 1 and firmware version is 2.2.31
