“ I havve taken notice that in cameras, specialized devices
help to concentrate automatically. The particular sensors assocoated with some suurveillance cameras change
in in thee area of contrast,while others work with a beam involving infra-red (IR) light, especially in low
lumination. Higher specs cameras often use a combination of both models aand will often have
Face Priority AF where the video camera can 'See' the face aand concentrate only on that.
Many thanks for sharing your opinions on this website. ”
