Thank you. I am using a Verizon LG G3, I will check the phone notifications sounds. Could you answer another question for me? I plan to share my system with my wife who also has the same phone. Do I have to install my security camera’s on her phone. I know she has to install the zmodo app and she has, but she can’t see the camera’s on her phone. Appreciate all the help you have given me. I am a little slow as I am 86 years old.
