In the realm of surveillance technology, the choice of lens plays a pivotal role in determining the quality and range of captured images. Among the myriad of options available, the 3mm Wide Angle IR Corrected CCTV Lens(CCL12030MP) stands out as a versatile and high-performance solution.

Technical Specifications

Sensor Size and Resolution

The 3mm Wide Angle IR Corrected CCTV Lens is designed to work seamlessly with a variety of sensor sizes, notably the 1/3″ format. This compatibility ensures high-resolution imaging, with some models supporting up to 4MP resolution, as seen in comparable products like the LC-C30-26 series from Shinwa. The lens’s ability to capture fine details makes it ideal for applications requiring precise visual documentation.

Focal Length and Field of View (FOV)

One of the standout features of this lens is its 3mm focal length, which provides an exceptionally wide field of view. This wide-angle capability is crucial for surveillance systems, as it allows for the monitoring of large areas with minimal blind spots. The exact FOV may vary slightly depending on the sensor size and resolution, but typically, it offers a broad horizontal coverage, enhancing situational awareness.

F-Number (FNO) and Light Transmission

The lens boasts an F-number of approximately 2.0, indicating its efficient light-gathering capabilities. This low FNO value ensures that the lens performs exceptionally well in low-light conditions, making it suitable for both day and night surveillance. The IR correction feature further enhances its nighttime performance by minimizing focus shift between visible and infrared light, ensuring clear images regardless of the lighting conditions.

Mount and Build Quality

The 3mm Wide Angle IR Corrected CCTV Lens features an M12 S-mount, a popular choice for CCTV cameras due to its compact size and robust build. This mount ensures secure attachment to the camera body, reducing the risk of misalignment or damage. The lens’s construction is typically made from high-quality materials, providing durability and resistance to environmental factors.

Advantages

Precise Thermal Compensation

Similar to the advanced lenses from Shinwa, this lens incorporates precise thermal compensation technology. This feature ensures that the lens maintains optimal performance across a wide range of temperatures, preventing image distortion or quality degradation due to thermal expansion or contraction.

Superior Low-Light Performance

The combination of a low F-number and IR correction makes this lens a standout performer in low-light environments. It captures clear, detailed images even in challenging lighting conditions, making it an excellent choice for 24/7 surveillance applications.

Minimal Ghosting and Flare

Effective stray light control is another advantage of this lens. It minimizes ghosting and flare, ensuring that images remain sharp and free from unwanted artifacts, even when subjected to strong light sources.

Optional Anti-Fog Function

Some models of this lens may offer an optional anti-fog function, which is particularly useful in humid or foggy environments. This feature prevents condensation on the lens surface, maintaining clear visibility at all times.

Applications

The 3mm Wide Angle IR Corrected CCTV Lens finds applications in a wide range of surveillance scenarios, including but not limited to:

• Blind Spot Monitoring (BSD): Its wide field of view makes it ideal for monitoring blind spots in vehicles or around buildings.
• Automotive Event Data Recorders (EDR): Capturing high-resolution images in automotive applications, such as dashcams or rearview cameras.
• Automatic Emergency Braking (AEB) Systems: Providing clear visual input for AEB systems to detect and respond to potential collisions.
• Lane Keeping Assist (LKA) Systems: Assisting in maintaining vehicle lane position by providing a broad view of the road ahead.

Conclusion

The 3mm Wide Angle IR Corrected CCTV Lens is a high-performance surveillance solution that combines wide-angle coverage, superior low-light performance, and robust build quality. Its technical specifications and advantages make it an excellent choice for professionals seeking reliable and high-quality imaging in various surveillance applications. Whether for automotive safety systems or general security monitoring, this lens delivers exceptional results, ensuring peace of mind and enhanced situational awareness.
