<p>A post detection unit (20) is disclosed for detecting content of a postbox (10). The post detection unit (20) comprises an image capturing unit (21) for capturing images of the interior (14) of the postbox. The image capturing unit (21) is arranged to capture a first image of the interior of the postbox before or during opening of the postbox, and to capture a second image of the interior of the postbox at closing of the postbox. Thereby an analysis of the first and the second image is enabled for detecting a difference between the first and the second image. Such a difference would represent a change in the content of the postbox. A corresponding method for detecting content of a postbox is also disclosed.</p> |
