Types of image sensors used in CCTV cameras ?

Image Sensor. There are two types of image sensors used in CCTV cameras: CCD and CMOS. CCD image sensors predate CMOS sensors and generally provide better low light sensitivity. CMOS sensors due to their lower cost, lower power consumption and smaller size are far more common in cameras today.

There are two types of image sensors used in CCTV cameras:  CCD and CMOS.  CCD image sensors predate CMOS sensors and generally provide better low light sensitivity.  CMOS sensors due to their lower cost, lower power consumption and smaller size are far more common in cameras today.

Image sensors range in size, but the most common are 1/4″ and 1/3″.  The image sensor dimension impacts the field of view for a given lens as well as the light sensitivity.  For example, a 1/3″ image sensor that is 1.3MP will have larger pixels than a 1/3″ 3MP image sensor and therefore have better low light sensitivity.
