· The Bosch LTC 0498 Series Dinion2X Day/Night Camera specifies a Dynamic Range of 120 dB (20-bit image processing) which is very good but the best digital SLR cameras have a dynamic range of 14 to 17 stops (or EV or bits). The dynamic range of a human eye is about 14 stops. How is it possible that a CCTV camera can be better than the human eye a good DSLR?
· The Signal-to-Noise Ratio of most CCTV cameras is about 50 dB. How is a good dynamic range possible with such a low S/N ratio? Thanks! Frank
