A:Answer I will try to answer your questions. The camera only reacts to motion not sound. When you have motion the camera will make a recording and you will receive a notification on your phone or email, at which time you can view the recording or would go live on that camera and be able to have sound along with the live feed. Not sure what you mean by hooked up? The cameras are wireless and connect to the Arlo Hub. You have several stored recording options, if you do not set up your own storage device you can purchase additional cloud storage space from their website. No, it works with Android also.
