A:AnswerNo, not unless you want more storage for recording, you can make that change when you hook it up and go to settings. You can set the record length also.
A:AnswerNot sure what you are asking, but maybe you need to re-aim the camera? Otherwise, the camera has a lag, about 2-5 seconds before it starts recording (it sleeps to conserve batteries, then wakes up when motion is detected, which takes a few seconds).
A:AnswerDownload the Arlo app and watch from any device.
Follow the setup and sign up for an account. When motion is detected you will get an email that you can click on and watch what takes place.
The Arlo app also lets you watch live stream from each device.
