The actual sensors involving some surveillance cameras change in in the area of contrast, while others employ a beam involving infra-red (IR) light, specially in low lighting. Higher spec cameras from time to time use a combination of both programs and could have Face Priority AF where the digital camera can ‘See’ some sort of face and concentrate only in that. Thanks for sharing your ideas on this blog. Reply Leave a Reply Cancel replyYour email address will not be published.
