Lenses for board cameras
Compact Board Lenses (M12 / S-Mount)
Board lenses, also known as S-Mount or M12 lenses (from the 12mm thread diameter), are small, compact lenses designed for direct mounting onto the camera's sensor board.
They are most commonly used in:
- Dome cameras: Where small size is important.
- Outdoor cameras with IR diodes: Many compact "bullet" cameras use this type of lens.
- Miniature and hidden cameras: Due to their small dimensions.
Like larger lenses, various focal lengths are available (e.g., 2.8mm, 3.6mm, 6mm), which determine the camera's viewing angle. Many are also IR Corrected to ensure a sharp image both day and night.
