Indoor camera night vision, clicking noise?

New customer here.
A few questions:
1) The indoor camera night vision does not work. I checked in the camera settings and NV is on.
2) in home mode (while sleeping) we hear clicking I think from the camera. when I turn SS off clicking stopped.
3) Is there a way to make the keypad chirp louder when you trigger the alarm, entering the home?
4) when not paying for full monitoring. Is there a way to just have SS notify me via the app and not trigger the siren?

Thanks
