What is the difference between infrared CCTV CCTV cameras and CCD cameras?

A CCD (charge couple device) is a device for the movement of electrical charge usually from within the device to an PL0035-2-SONY-CCD-Lens-CCTV area where the charge can be manipulated, for example conversion into a digital value. CCD is the heart of a CCTV (Closed Circuit TV) camera and is widely used in professional, medical, and scientific applications where high-quality image data are required. The difference between CCTV cameras with CCD camera is significant- as noted in our other posts infrared CCTV cameras can be used in the dark even though there is no light and able to capture images and videos, while the CCD camera can only work in the light and not able to capture images and record video  in the dark.
Despite the difference between CCTV camera and charge coupled devices in darkness, the advantage is on the CCD camera to record clear and bright video, besides CCD camera can be changed depending on the lens  when they are used for security systems.They commonly respond to 70% of the Incident light (meaning a quantum efficiency of about 70%,) making them more efficient than photographic film, which captures only about 2% of the incident light. When comparing the prices CCD cameras used to be relatively inexpensive and well suited for most indoor needs, while CCTV cameras  are used usually for outdoor  experiences and are more expensive. 
The differences and advantages are here and the choice is yours based from criteria wheter you want to use either area who want to install CCTV in an area of darkness in the evening or at night lighting available area.
