This camera is one of the best around for reversing or permanent rear view on. It has the Sharp CCD sensor installed which in my opinion is the very best available. The night vision is simply unbelievable, the daytime picture has lovely vivid colours. If you are unsure of spending the extra money on CCD as opposed to getting the cheaper CMOS cameras then read the paragraph below. This explains how CCD cameras may have the same or slightly better resolution, the unformity which isn't measured is better in CCD than CMOS and is a more important factor than resolution or TVL figures. The body is specially made for us in white, as white bodied cameras are very hard to find. This is ideal for white van man, motorhome owners and caravan owners. If you are after the VERY best camera then this is your camera. |

CMOS VS CCD
CCD (charge coupled device) and CMOS (complementary metal oxide semiconductor) image sensors are two different technologies for capturing images digitally
Both types of imagers convert light into electric charge and process it into electronic signals. In a
CCD sensor, every pixel's charge is transferred through a very limited number of output nodes (often just one) to be converted to voltage, buffered, and sent off-chip as an analog signal. All of the pixel can be devoted to light capture, and the output's uniformity (a key factor in image quality) is high. In a
CMOS sensor, each pixel has its own charge-to-voltage conversion, and the sensor often also includes amplifiers, noise-correction, and digitization circuits, so that the chip outputs digital bits. These other functions increase the design complexity and reduce the area available for light capture. With each pixel doing its own conversion, uniformity is lower
So we can see that CCD has higher uniformity which gives a better quality, CMOS has a lower uniformity (lower quality). If you ever get a chance to run them side by side as I've done, you can see the difference, especially at night. |
