Vivotek AL-246 2.8-8.5mm Varifocal Lens with P-Iris

The Vivotek AL-246 is a professional-grade varifocal lens designed for demanding surveillance applications where adaptability and optical performance are critical. With a 2.8-8.5mm focal range, F1.2 aperture, and integrated P-Iris control, this lens delivers exceptional image clarity across varying lighting conditions and coverage requirements. Built for integration with Vivotek network cameras and P-Iris compatible systems, the AL-246 enables operators to optimize field of view and depth of field with precision, making it an ideal choice for facilities requiring flexible monitoring solutions.

Key Features

• 2.8-8.5mm Varifocal Range: Provides flexible focal length adjustment from wide-angle scene capture to detailed close-up views without changing lenses
• F1.2 Fast Aperture: Maximizes light transmission for superior low-light performance and enhanced image quality in challenging illumination
• P-Iris Technology: Delivers precise iris control to optimize depth of field, sharpness, and contrast across the full focal range
• High-Resolution Ready: Compatible with modern high-resolution camera sensors for crystal-clear surveillance footage
• Robust Design: Engineered for both indoor and outdoor deployment with durable construction
• Seamless Integration: Works with Vivotek network cameras and other P-Iris compatible surveillance platforms

Technical Highlights

The AL-246's varifocal design eliminates the need for multiple fixed-focal lenses, reducing inventory and installation complexity. The F1.2 aperture is particularly valuable in retail environments, parking facilities, and indoor spaces where ambient lighting fluctuates throughout the day. P-Iris technology ensures consistent image sharpness by automatically adjusting the iris mechanism, which is essential for accurate subject identification and forensic-quality video.

Ideal Applications

The AL-246 excels in retail stores, office buildings, warehouses, parking areas, and outdoor perimeter monitoring where versatile coverage and reliable low-light performance are required. Its adaptability makes it suitable for fixed-position surveillance where the field of view may need occasional adjustment without physical lens replacement.
