That will tell you if it's the camera or battery. However, the system came with a US warranty so that's where you'd have to send it for any issue. Possibly Amazon would exchange the system for you.

Tried again and again over the next few days and still not working. Wondering if I can send&nbsp;this camera back to anywhere in Asia or must return to the States for service /&nbsp;exchange a new one?</P> Tue, 31 Jan 2017 13:46:31 GMT https://community.arlo.com/t5/Arlo-Pro/One-camera-failed-to-connect/m-p/1219525#M6460 Tsai56 2017-01-31T13:46:31Z https://community.arlo.com/t5/Arlo-Pro/One-camera-failed-to-connect/m-p/1219735#M6477 First, try plugging the camera in or swap batteries between cameras.
