Can one tell me what I must change so that I can make ordinary photos?

Can one tell me what I must change so that I can make ordinary photos? The same as other s.jeder Camera synonymous if the recording is overexposed: Aperture next close or / and shorten exposure time. If both is not possible, a Graufilter put before the Optics.

Hello, s.der Camera (surveillance camera) I can not set apart from the sharpness and the fits.
Can it s.Recorder lie? It is a PMP - saves on SD card in the MP 4 format. If the recorder with the flood of data to be overwhelmed?
When I connect the camera s.TV it will be better, but the pan into the light, it is synonymous first everything overexposed. But then goes.
Graufilter? Is there something for such a small camera? Diameter of 19 mm Lens s.Außenring!

If the recorder with the flood of data to be overwhelmed? If it were, there would not be an over-exposure, but rather to be dropped frames, so Jerkiness picture.
When I connect the camera s.TV it will be better ... Indoors, it is nowhere near as bright as outdoors. If it is still inside so it's just outside the camera is too light and the automatic diaphragm can no longer compensate. Try also with a Graufilter.
Graufilter? Is there something for such a small camera? Diameter of 19 mm Lens s.Außenring! For a first test just slightly tinted transparent film, with the tape in front of the optics mounted. If this trick and proved to be Bildqaulität better, you could in the same way synonymous a Schraubfilter before Lens mount. Ø 19 mm are just very little, but bigger Schraubfilter (from Ø 27 mm) there is in any case.
