Surveillance technology has evolved dramatically, with lenses playing a pivotal role in capturing sharp, reliable footage across diverse environments. Whether safeguarding public spaces, monitoring traffic, or securing industrial facilities, the right surveillance lenses ensures clarity, adaptability, and performance.

TOWIN, a leading optical lenses supplier based in China, specializes in designing and manufacturing high-quality surveillance lenses tailored to meet global demands.

1. S-Mount Lenses: Compact Powerhouses for Embedded Surveillance

M12/S-Mount lenses, often dubbed “board lenses” or “miniature lenses,” are engineered for compact surveillance systems. Their standard M12X0.5 thread allows direct threading into PCB cameras, making them ideal for embedded applications where space is limited.

Key Parameters & TOWIN’s Edge

Focal Length: Wide-angle (2.8mm–6mm) and fisheye options for 180°–360° coverage.

• Aperture: Fixed or variable iris for low-light sensitivity.
• Distortion Control: TOWIN’s Low Distortion lenses minimize image warping, critical for facial recognition.
• Applications: Drones, body cameras, and smart doorbells.

TOWIN’s M12 lineup includes Fisheye lenses for panoramic views, Pinhole lenses for covert operations, and Automotive lenses for vehicle-mounted systems. Their multi-coating technology reduces glare, ensuring crisp day/night performance.

2. C-Mount Lenses: Industrial-Grade Precision for Machine Vision

C-Mount lenses, with a flange focal distance of 17.526mm, are the backbone of industrial surveillance. Used in Machine Vision (MV), Factory Automation (FA), and 3D cameras, they excel in high-speed, high-resolution environments.

Key Parameters & TOWIN’s Edge

• Resolution: Up to 50MP for ultra-detailed imaging.
• Focal Range: Fixed (e.g., 8mm) or zoom lenses (e.g., 12–50mm) for flexibility.
• Iris Control: Manual, DC Auto, or P-Iris for dynamic lighting conditions.
• Applications: Quality control in manufacturing, robotic guidance.

TOWIN’s C-Mount lenses feature IR-corrected glass for 24/7 operation and ruggedized housings to withstand harsh factory conditions. Their “ITS lenses” are optimized for traffic monitoring, capturing license plates even in motion.

3. CS-Mount Lenses: High-Resolution Surveillance for Modern CCTV

CS-Mount lenses (flange distance: 12.526mm) are designed for CCTV, network, and IP cameras. Their compatibility with megapixel sensors makes them a staple in video surveillance.

Key Parameters & TOWIN’s Edge

• Vari-Focal Lenses: Adjustable focal lengths (e.g., 2.8–12mm) for versatile coverage.
• Day/Night Performance: Multi-coating and IR correction eliminate focus shifts.
• Iris Types: DC Auto Iris for rapid light adaptation.
• Applications: Urban security, retail analytics.

TOWIN’s CS-Mount series includes megapixel lenses with <1% distortion and vandal-resistant designs for outdoor use. Their “traffic lenses” integrate seamlessly with Intelligent Traffic Systems (ITS).

4. Wide-Angle & Fisheye Lenses: Expanding Surveillance Horizons

For applications requiring expansive coverage, wide-angle and fisheye lenses eliminate blind spots.

Key Parameters & TOWIN’s Edge

• Field of View: Up to 360° for fisheye lenses.
• Edge Distortion: TOWIN’s algorithms correct barrel distortion in real time.
• Low-Light Capability: F/1.2 apertures capture usable footage in dim conditions.
• Applications: Stadium surveillance, warehouse monitoring.

TOWIN’s 190° Ultra-Wide lenses reduce the need for multiple cameras, while their fisheye dewarping software simplifies post-processing.
