Appearances are deceptive 3

What a pity. Maybe I should stumble on the extremely reasonable price, but some product reviews sounded very encouraging and so I let the product arriving from China. Software runs on Win7 and I get in sufficient lighting actually displayed an image on a laptop. The one star I forgive just because the camera is not broken, but it is good definitely not as a tube camera. Once it gets dark the camera sees nothing. And I mean really nothing. The four LED rich just the first three cm in front of the lens or COMS chip to illuminate if there is something that can be illuminated. For an illuminating and useful view into the dark pipe landscape it is not enough. The screen on the connected laptop stays black. In this immediate area but the image is blurred and the image section shown anyway useless for diagnostic purposes in the size of a 2-piece.
I wanted to send the camera back, but would have to bear the freight costs. Instead, I accepted the 15% discount and will now check off the camera under the topic of life experience and send to disposal.
