David, low light level (0.01Lux) video cameras equipped with photographic lenses rather than the the ones used in the security business) show satellites to fainter than mag 6. Camcoder types usually stop about mag +3. In regard to still photo, the exposures required are longer than for domestic use and you have to find a camera with exposure control. Personally I havent seen any cheap ones ALL uncooled CCD chips are saturated by about 10 seconds with thermal electrons. To go longer and fainter one has to cool the chip.
