Board Camera Lenses

Compact Board Lenses (M12 / S-Mount). Board lenses, also known as S-Mount or M12 mount lenses (from the 12mm thread diameter), are small and compact lenses designed for mounting directly on the camera sensor board. They are most commonly used in dome cameras where small size matters, outdoor cameras with IR LEDs (many compact bullet cameras use this type of lens), and miniature and hidden cameras.
