What are the differences between CCD camera and CMOS camera?

Simply put, the big difference between a CCD camera and a CMOS camera is that the former collects analog signals, distinguished by the number of lines, and the latter collects digital signals distinguished by pixels.

CCD is the abbreviation of Charge Coupled Device, it is a semiconductor imaging device, so it has the advantages of high sensitivity, anti-glare, small distortion, small size, long life, anti-vibration and so on.

In the security system, the current image generation mainly comes from the CCD camera. CCD is the abbreviation of charge coupled device (charge coupled deice). It can convert light into electric charge and store and transfer the electric charge. It can also take out the stored electric charge. The voltage changes, so it is an ideal camera element. The CCD camera composed of it has the characteristics of small size, light weight, partial influence of magnetic field, anti-shock and impact characteristics, and is widely used.

CMOS is called "complementary metal oxide semiconductor". CMOS is actually just a technology that places transistors on silicon blocks, and has no more meaning. The sensor is called a CMOS sensor just to distinguish it from the CCD sensor, and has nothing to do with the real method of the sensor processing images.

Simply put, the advantage of the CCD camera is that the nighttime sensitivity is good. The advantage of the CMOS camera is that it can obtain high-definition pictures with more than 1 million pixels, which is unmatched by the CCD camera.
