I join previous speakers in most respects and would simply add / correct: The black and white phenomenon I can not confirm. For VGA 640x480px Camera makes very good pictures. Since you can adjust the brightness by wheel to the USB connector, you just have to set the correct brightness. That the camera can not be used for a tank, should be clear. I've searched just a hole in a sewage pipe 110s (and found) - for the camera was all worth the money (just think of crafts bill!). To shortcoming "flexible cable": Also here - in the (continuous) tube no problem sometimes 3-5m to push through horizontal. The more sheets, the worse. I had, however, due to the previous review can expect a truly flexible cable ... Of course it is not as rigid as an ordinary 3-wire electrical installation cables - but as flexible as the power cord a stereo system, it is not.
