Your Blink home screen can display a thumbnail as a preview for each camera. These thumbnails are created by tapping the thumbnail button .
When a new camera is added, a blank thumbnail is shown and the camera name is the serial number.
After a new thumbnail photo is taken, it displays beneath the camera's name. You can update the thumbnail photo by tapping again.
If you take a thumbnail when the infra-red (IR) camera is set to On (or set to Auto and a low light level has activated the IR camera function), the image appears without color and heat is portrayed by brightness.
Thumbnail photos remain until you manually update them.
