CCD / CCTV vs CMOS CameraPublished: March 4, 2012
Charge Coupled Device (CCD) Camera and Closed Circuit TeleVision (CCTV) Camera are used in producing good quality Digital Video Recordings and Still Photos (for the surveillance purposes).
Complementary Metal Oxide Semiconductor (CMOS) Camera are also used for the same purpose but they provide little poor quality as compared to the CCD/CCTV Cameras. In a CMOS Camera Sensor, each pixel has its own charge to voltage conversion, noise correction, amplifier, digitization circuits and chip output bits.
CCD/CCTV camera are of two types : Digital and Analogue, which are able to send the signals to any PC/Laptop or a Storage Device like Tape Recorder. While CMOS Camera can be plugged to any USB Device, to get all data from the camera.
Here are some major differences between CCD/CCTV and CMOS Cameras :
1. CCTV/CCD Cameras are made up of semiconductors, capacitors and sensors which produce little better videos and photos as compared to the CMOS Cameras.
2. CCD/CCTV Cameras are more sensitive and expensive than the CMOS Cameras.
3. CCD Camera consumes more power than the CMOS Camera.
4. While comparing the cost, CCD Camera costs more than the CMOS Camera.
5. CMOS Sensors are more susceptible to Noise as compared to the CCD Cameras. This noise can contribute to gap in the image quality.
Here is the comparison of Image quality of CCD and CMOS Camera :
