Product Summary

The A4Z2812CS-MPIR lens offers 3 MP resolution, varifocal 2.8-10 mm range, and IR correction, making it perfect for high-performance imaging in various applications.

Enhance your imaging systems with the A4Z2812CS-MPIR 2.8-12mm Varifocal Lens—a high-performance lens designed for superior clarity and adaptability across diverse lighting conditions. Designed to meet the rigorous demands of modern surveillance and industrial imaging applications, this lens delivers exceptional image quality, making it an indispensable component for professionals seeking reliability and precision.

Adjustable Focal Length for Versatile Imaging

Featuring a 2.8-12mm varifocal range, this lens offers unparalleled flexibility in capturing scenes. Whether you need a wide-angle view for broad area surveillance or a narrower focus for detailed inspections, the adjustable focal length allows you to customize the field of view to suit your specific requirements. This adaptability makes it ideal for dynamic environments where imaging needs can change rapidly.

Megapixel Resolution for Crisp, Detailed Images

The lens supports megapixel resolutions, ensuring high-definition image capture that preserves intricate details. This is crucial in applications like facial recognition, license plate reading, and quality control inspections, where clarity and precision are paramount. The superior optical design minimizes distortion and aberrations, providing sharp and accurate visuals.

Infrared Correction for Day and Night Performance

Equipped with infrared (IR) correction, the A4Z2812CS-MPIR lens maintains consistent focus between visible and infrared light spectrums. This feature is essential for 24/7 surveillance operations, as it eliminates focus shifts when switching between day and night modes. The lens ensures that images remain sharp and clear, regardless of lighting conditions.

CS Mount Compatibility for Easy Integration

Designed with a standard CS mount, this lens offers broad compatibility with a wide range of security and industrial cameras. The CS mount design simplifies installation and integration, allowing for seamless upgrades or replacements in existing systems. Its robust construction ensures durability and long-term performance in demanding environments.

Auto Iris Control for Optimal Exposure

The lens features auto iris control, which automatically adjusts the aperture in response to changing light conditions. This functionality ensures optimal image brightness and contrast, preventing overexposure in bright settings and underexposure in low-light scenarios. Auto iris is particularly beneficial in outdoor surveillance and industrial applications where lighting can vary significantly.
