Why is there a camera app on the Telus 21T?

Does the box have a camera somewhere?

[A-B]

Not an option for us, but the manufacturer builds the boxes that way as other providers/companies may utilize it.

As @A-B mentioned, it is built in to the Android TV operating system to support USB and BLE-connected cameras. There is no built-in camera. You can disable the Camera app or customise the app settings in Settings > Apps.
