I am thinking of buying a new CMOS reversing camera and I was wondering what the new technology CMD car rear-view reversing camera was, could you tell me?
A CMD is a sensor (high-definition) that resides in a CMOS (Complementary Metal Oxide Semiconductor) camera.
Let me explain.
Basically, there are two different types of rear-view reversing cameras for cars on the market. The first type, called a CCD (Charge Coupled Device) is the more expensive of the two cameras as it uses digital technology and has higher clarity. The second type, the CMOS camera is cheaper because it is mass-produced and uses analogue technology.
The CMD sensor, therefore, produces a better image than a standard CMOS sensor, but both of these sensors are inferior to the CCD sensor, which uses digital technology.
The latest CMD in the CMOS camera range is the CMD PC1030, which is a tiny 18 mm in diameter. This camera is said to have a higher clarity than the standard CMOS rear-view reversing camera (OV7050 or OV7049). In fact, this CMD rear-view reversing camera is said to be as good as the Sharp® CCD sensor during the day.
However, the CMD camera has a similar night vision to that of a CMOS (standard) camera. Therefore, if you are seeking to use your camera mainly at night, then it is suggested that you consider purchasing a CCD camera, as these have the clearest night vision.
1. Before you purchase a camera consider when you will be using it the most and why you feel you need it, so that you buy the right camera for you; and
2. Remember to ask questions if you are not sure of what you are buying, so that you can make an informed decision.
