The UniFi Protect mobile app allows you to control your cameras and other home security devices directly from your smartphone, tablet, or PC. It also works with the cloud-based version, which is accessible from anywhere on any device.

You can set up a passcode on your phone and tablet, or on the app. When you login, you are prompted to enter the code. You can also sign in with your UniFi account.

All the device settings and settings that you see in the cloud can be accessed in the app. You can set the mode, password, camera views, notifications, alert notifications, time-lapses, zones, doors, windows, and more, right from the app.
