Surveillance systems rely heavily on the precision and reliability of CCTV lenses to capture clear, actionable footage. Whether monitoring public spaces, industrial facilities, or residential areas, selecting the right lens ensures optimal image quality, coverage, and adaptability to varying lighting conditions.

Towin, a leading optical lenses supplier based in China, offers a diverse range of CCTV lenses tailored to meet the demands of modern security applications.

Types of CCTV Lenses: Towin’s Specialized Offerings

CCTV cameras utilize different lens types based on mounting standards, focal lengths, and environmental requirements. Towin’s portfolio includes CS-mount lenses, C-mount lenses, and specialized variants designed for surveillance. Below is a detailed breakdown of each type and its relevance to CCTV systems.

1. CS-Mount Lenses: Compact Precision for Surveillance

CS-mount lenses are a staple in CCTV systems due to their compact design and compatibility with CCD/CMOS cameras. These lenses feature a flange focal distance of 12.526 mm, making them ideal for security cameras where space is limited. Towin’s CS-mount lenses come in two primary configurations:

• Fixed Focal Length: Perfect for static surveillance scenarios, these lenses maintain a consistent field of view (FoV).
• Vari-Focal Length: Adjustable focal lengths (e.g., 2.8–12 mm) allow users to zoom in or out without changing the lens, offering flexibility in dynamic environments.

Key Parameters:

• Aperture Types: Manual Iris, DC Auto Iris, and P-Iris for precise light control.
• Resolution: Megapixel-rated lenses support high-definition surveillance.
• IR Correction: Multi-coating technology ensures clarity in day/night security cameras.

Towin’s CS-mount lenses are widely used in CCTV cameras, network cameras, and IP cameras, providing crisp images even in low-light conditions.

2. C-Mount Lenses: Industrial-Grade Durability

C-mount lenses, with a flange focal distance of 17.526 mm, are engineered for robust industrial applications. Often referred to as MV lenses (Machine Vision) or FA lenses (Factory Automation), they excel in environments requiring high durability and precision. Towin’s C-mount lenses are also deployed in traffic monitoring cameras for Intelligent Traffic Systems (ITS), where reliability under harsh conditions is critical.

Key Parameters:

• Thread Size: M12X0.5 standard for easy integration with PCB cameras.
• Lens Types: Low distortion, fisheye, and wide-angle options cater to diverse surveillance needs.
• Application: Machine vision, 3D cameras, and traffic management systems.

3. M12/S-Mount Lenses: Miniature Marvels for Board Cameras

M12 lenses, also known as S-mount lenses or board lenses, are ultra-compact solutions threaded directly into PCB cameras. Their tiny form factor makes them ideal for discreet surveillance in drones, robots, and embedded systems. Towin offers:

• Low Distortion Lenses: Minimize image warping for accurate facial recognition.
• Fisheye Lenses: Provide 180°–360° panoramic views for wide-area coverage.
• Pinhole Lenses: Concealed installation for covert operations.
• Application: Board cameras, automotive surveillance, and compact security devices.
