I have the B 120, and am using V 2.2.0 App , IOS 6.0.2 on an Iphone 5. While I am connected to the camera on 4G (p2p), the night vision stays turned off and does not turn on despite changing the settings. How could this be fixed?

Also, there is quite a bit of white noise when the app is turned on. I have decreased the audio alert level to 1% without any change in the white noise. Is there a solution for this?

Thank you in advance for your response.
