Dongwonsecurity 0 Posted June 17, 2010 Hi All, Bosch showed new camera developed with 20bit(DSP). Even it is 540TVL, The image must be very rich and wonderful. I know now most of high resolution camera is based on 8~10bit technology. Which manufacturer use the highest bit rate for camera now? Share this post Link to post Share on other sites
Baylab 0 Posted June 19, 2010 I don't think the number of bit in DSP system does matter. The dynamic range of the top quality CCD sensor (for video surveillance application) is not larger than 60dB, that means 10bits. Actually, the bits of frame grabber is more important: the low end products just use 8-bit ADC, some product with better quality use 9-bit or 10 bit ADC. I have never heard any product which use 12bit ADC. Share this post Link to post Share on other sites

New products of Bosch supports 20bit DSP (LTC 0498 Series Dinion2X Day/Night Camera)<<- if someone has seen the image, PLEASE comment it..! Share this post Link to post Share on other sites
