Privacy Zones are only available for the Blink Video Doorbell, Indoor (gen 2), and Outdoor cameras. A Privacy Zone is an area you select and Blink adjusts the camera firmware to not allow any video information or motion alerts to ever leave the camera.
Examples of why you may use Privacy Zones would be to exclude a neighbor's door, or window from being viewed or recorded by your camera. Up to two Privacy Zones can be set and they are easily recognized as grey areas of the screen.
To use this feature, access the settings of the camera that you want to modify.
Tap the Privacy Zones button to view the screen. You now see the camera thumbnail with a grid pattern. You can also tap the Update Photo button to refresh the thumbnail image. Tapping Reset Privacy Zones deletes the existing zones. Privacy Zones cannot be edited, only deleted (reset) and recreated.
Tap and drag on the screen to draw up to two zones you want selected within the thumbnail image. Once zones are created they can be moved and resized by dragging on the blue dots at the corners of each.
After your zones are drawn, tap Done to save them. You are then returned to the Settings screen, and the grid pattern now reflects the zones you just set.
You can tap Save to apply all settings changes and be sent to the Home screen.
If you tap Zones again, the Zones screen now shows the Privacy Zones in black to help contrast with activity zones, which are grey in the Activity Zone view.
