Applications

The AL-243 is ideal for surveillance installations in parking facilities, retail environments, transportation hubs, and large public venues where variable distance coverage and precise exposure control are critical. The varifocal design eliminates the need for multiple fixed-focal lenses, reducing installation complexity and system cost while maintaining high image quality across dynamic lighting conditions.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The AL-243 represents a strategic choice for integrators requiring a single, versatile lens solution across multiple camera positions. The combination of a bright F1.4 aperture and P-Iris technology addresses a common challenge in surveillance: balancing light sensitivity with precise iris control. Unlike fixed-iris lenses, the motorized P-Iris actively adjusts aperture in real-time, maintaining consistent depth of field and preventing image washout in high-contrast scenes.

The 7-22mm range (approximately 3.1x zoom) provides sufficient flexibility for most indoor and outdoor coverage scenarios without requiring wide-angle or telephoto extremes. For Vivotek IP8166 and IP9171-HP deployments, this lens offers native integration, ensuring seamless auto-focus and iris coordination. The 1/2.7" image circle specification confirms compatibility with modern 4K and high-megapixel sensors, future-proofing installations.

Durable construction supports both climate-controlled and exposed mounting, making it suitable for diverse facility types.
