CCTV Lens and Image Sensor Considerations

Lens Form Factors for Image Sensor

Sensor sizes are specified by the diagonal and mainly include 1/4″, 1/3”, and 1/2″. A lens can fit in with a smaller sensor. When using with a larger-sized sensor, for example, a 1/4” lens with a 1/3” sensor, the situation of dark
corners in the image will be caused.

View Angle

View angle is determined by the focal length of the lens and the sensor size. The shorter the focal length and the larger the sensor size , the wider the view angle.
