difference ccd camera and cmos camera


What are the difference between ccd camera and dome camera?
the difference is in the quality of the image sensor of both camera.
A CMOS camera has a less-expensive image sensor, means low quality picture. The other benefits of CMOS are size, and low-power consumption. Most CMOS cameras can even be operated for several hours on a single 9-volt battery! The low-power consumption comes at a price however. CMOS cameras have a lower resolution and less color quality than the CCD cameras.

CCD Cameras are much more sensitive to power fluctuations, due to the fact that the CCD Sensors have 4 integrated processors compared to the one processor found on a CMOS sensor. CCD cameras usually have much better picture quality, resolution and color balance. The drawback of a CCD camera is higher-power consumption and sensitivity to minute voltage changes

CCD cameras do not like direct sunlight. That can damage the image sensor.

CCD sensors have been in mass production for a long period of time and therefore a more mature product than CMOS sensors. CCD sensors tend to produce higher quality and more pixels. As a result, the images produced by CCD sensors are much better than those from CMOS sensors.

The third major difference between these two sensors is that the manufacturing costs of CMOS is much less expensive than CCD.

Based on these differences, you can see that CCDs tend to be used in cameras that focus on high-quality images. CMOS sensors tend to have lower quality, lower resolution and lower sensitivity. There is a trade-off between higher image quality but higher power consumption (CCD) compared with lower image quality but longer power consumption (CMOS)
