When a camera is first installed, the serial number is entered for the camera name, and its thumbnail image is blank.
Tap the camera name to change it, enter the new name, then tap OK to save.
Tap the thumbnail icon to take a new thumbnail image. The thumbnail remains until you refresh it with this button. With a doorbell, the thumbnail image is refreshed when the ringer button is pressed.
