hi, I'm relatively new to this, I have been using mostly appro lc-7222 box cameras wich seem to be a great deal for around 200-250$ the quality being more than ok. However for the sake of keeping up with technology I decided to test an arecon vision av3100m 3 megapixel camera. I am using a computar 5mm 1/2" lens, but the images I get (indoors) are nowhere near the quality of the downloads they have available on their website. Those look like real HDTV footage, mine are alot less sharp, plus there's clearly visible noise. I tried all available settings, can't seem to find any shutter speed settings so I could lower the shutter speed for less noise. At current settings the image quality just doesn't justify the price of this camera. I am located in Romania an I get theese wholesale for $800 and the appros for $250... Please if anyone has some tips, maybe this camera works best with a diffrent lens setup or diffrent lighting conditions. Oh and another thing, it always seems dark, whether I use auto exposure on or off, with the lens iris opened all the way...
