As an increasing number of businesses utilize high-definition cameras for industrial and surveillance purposes, along with security, choosing the appropriate lens is vital. You may be installing a security surveillance system or replacing machine vision equipment, and it’s absolutely essential to know how to choose the ideal M12 board lens for your camera.
What Is an M12 Board Lens and Why Would It Be Important to Your Camera?
M12 lenses are small-form-factor lenses with a universal threaded screw (M12) employed on cameras within industrial, automotive, and security usage. They are so general and small in form that they are particularly coveted within board cameras. The M12 lens is the determinant of camera quality, viewing area, and how the camera will perform regardless of lighting conditions. The use of the correct M12 board lens will cause your camera to work to the fullest extent of real conditions either within a factory environment or an external setting.
What Does the M12 Lens Have to Do with Camera Performance?
M12 lens is also the main factor responsible for the quality of an image. Focal length, aperture size, and field view of the lens determine the total amount of captured light, how sharp the pictures are, as well as how much of a scene can be captured by a camera. Matching the lens to the camera sensor will be needed in order for the camera to capture the maximum in image sharpness and required detail level.
Important Things to Remember When Choosing an M12 Lens
1. Focal Length: How Far and How Wide Can Your Lens See?
The focal length of the M12 lens determines the zoom ratio and if the camera can image objects at different distances. Short focal length, i.e., Normal 2.8mm 5mp F1.8 m12 mount cctv board lens, provides wide vision, most appropriate for monitoring large areas. Long focal length, i.e., 5mp 25mm m12 board Lens, allows the camera to image far objects at higher resolution.
Upon the choice of M12 lens, one must pick a focal length that will best suit the intended application. Both security and surveillance applications need the M12 wide angle board lens. In near-in and close detail requirements in machines vision application, the M12 telephoto focal length lenses should be used.
2. Aperture Size: Controlling the Light
The size of the aperture also determines the amount of light that passes through the lens and on to the camera sensor. Large apertures (smaller f-stop) allow more light through and produce brighter images, especially where minimal lighting is present. A small aperture (large f-stop) limits light, and this comes in handy to use during daylight shootings with excess lighting.
For example, the F1.0 3.9mm m12*p0.5 mount star-light board lens provides more low-light ability and is thus apt for day-and-night camera uses. Conversely, higher values like F4 M12 mount cctv board lens are appropriate for light intensities but are difficult to manage under low light and even absorb more light under low-light conditions.
3. Field of View: How Much Can You See?
Field of view (FoV) is one to be aware of when selecting an M12 board lens.
FoV defines the amount of space your camera can cover with a single capture. Wide FoV lenses (focal lengths of less than 3mm) are ideal for monitoring large areas like parking garages or warehouses. Small FoV lenses and extended focal lengths are however best to use in applications like license plate reading or facial recognition.
4. Image Quality and Resolution: The Higher, The Better
Resolution is necessary so that your camera is able to record clear and crisp pictures. M12 lenses have varied resolutions such as high-definition (HD) and 4K. A lens of the same resolution as that of the resolution of the camera sensor is responsible for achieving maximum possible sharpness of the image without pixelation.
For applications where sharper definition images are required, 4K M12 lens are designed for cameras that require very sharp definition, i.e., facial recognition or factory automation.
5. Lens Coating: Getting the Best Out of Changing Light Conditions
Lens coating performance plays a significant role in managing reflections, reducing distortion of light, and facilitating the passage of light through the lens. Multi-layer anti-reflective coated M12 lenses are perfect for capturing clear images either in sunny or low-light environments. Outdoor installed security cameras under sunlight-intensive areas where reflection-based image distortion occurs need to be given special consideration to be riveted on coatings.
The large manufacturers like Hangzhou Ai Ke Electronics Co., Ltd. (AICO) employ superior coating technologies like broadband AR coatings featuring up to 90 layers. They provide high transmission of light and very little distortion even under intense light. This type of coating enhances image quality, especially for use in surveillance under security and video conferencing.
