CMOS Vs CCD Sensor....

As comparison between CMOS and CCD sensors as below:

CMOS sensor:

- Read all the pixels of the image on one time then transfer the data to digital all together on one time.

- Requiring less power (Saves more battery power)

- Size of image is too much big.

-The resolution of the image is more clear

CCD Sensor:

- Read the pixels of the image one by one then transfer each pixel to digital alone.

- requiring more power ( Battery dead faster)

- Size of the image is small.

- Usually uses in Analogue camera

- The resolution of the image is less clear

Question:

My question is why CMOS sensor is usually using in IP network camera and all we knows that the resolution of the IP cameras is better than analogue cameras? While in the comparison above we observed that CCD sensor has more clear in the image than the cameras that carries CMOS sensor.

Please clarify briefly?


The End of CCDs in mainstream surveillance is here.

In general, the best cameras in the market today use CMOS sensors, and development/manufacturing is focused on producing CMOS, not CCD sensors.

"why CMOS sensor is usually using in IP network camera"

CMOS is less expensive / more practical for MP / multi-megapixel cameras, one of the key reasons that CCDs are going away in surveillance.

Thanks for clarification. It's clear now But regarding the lens sizes 2/3" 1/2", 1/3",1/4" Why 1/3" is mostly used in IP cameras and 1/4" is mostly used in analogue cameras? Why the 2/3" and 1/2" is not required these days, could you please explain the difference?

One reason IP cameras have bigger sensors is that they have more pixels on average than Analog cameras. Though there are plenty of IP cameras with 1/4" sensors, and plenty of analog ones with 1/3" sensors, so you can't assume it's bigger just because it's an IP camera.

As for the sensors of 1/2" and larger, the cost of the imager and the larger associated optics required increase the price to a point where it is hard to justify the added cost for whatever added performance may be gained.

CMOS sensors generally read one row at a time, rather than reading the entire image at once. This can create some interesting artifcacts for fast moving objects. For example, propellers and rotor blades may seem to curve. This occurs because each row is read out sequentially, so the blades are in a different position at each read interval.
