Vivotek AL-24B 3.6-17mm Surveillance Lens P-Iris
The Vivotek AL-24B is a professional-grade surveillance lens engineered for 1/1.8-inch sensor cameras, delivering exceptional optical performance across diverse security applications. With a 3.6-17mm focal length range and 4.7x optical zoom, this lens provides the flexibility to frame wide overviews or capture critical detail—all from a single lens. The large F1.5 aperture ensures superior light-gathering capability, making it ideal for installations requiring reliable performance in variable lighting conditions, from bright daylight to low-light environments.
Key Features
- Versatile 3.6-17mm Focal Length: 4.7x optical zoom range adapts to wide-area coverage and detailed zoom requirements without lens changes
- Large F1.5 Aperture: Maximum light transmission for superior low-light performance and reduced image noise in challenging illumination
- P-Iris Technology: Precision iris control automatically optimizes aperture position for enhanced depth of field and consistent sharpness across the focal range
- 1/1.8-Inch Sensor Optimization: Engineered specifically for larger sensor formats to maximize resolution and image detail capture
- Durable Construction: Rugged design withstands indoor and outdoor environmental demands, maintaining optical integrity over time
- Seamless Integration: Direct compatibility with Vivotek IP cameras featuring 1/1.8-inch sensors ensures plug-and-play installation
Technical Highlights
The AL-24B's P-Iris mechanism provides automated aperture control that maintains optimal image sharpness and depth of field consistency, independent of subject distance or lighting changes. This advanced iris control is particularly valuable in surveillance scenarios where dynamic lighting conditions could otherwise degrade image quality. The 4.7x zoom range—from 3.6mm wide angle to 17mm telephoto—enables operators to monitor expansive areas while retaining the ability to zoom in on specific zones of interest without sacrificing detail.
Ideal Applications
The AL-24B excels in demanding surveillance environments including city-wide monitoring systems, traffic control zones, large commercial facilities, transportation hubs, and critical infrastructure protection. Its combination of wide coverage, zoom capability, and low-light performance makes it suitable for installations where a single lens must reliably perform across multiple time-of-day and weather conditions.

The AL-24B represents an excellent choice for integrators seeking a versatile, single-lens solution for mid-to-large format sensor cameras. The P-Iris technology distinguishes this lens by automating iris optimization, reducing the need for manual iris compensation and improving consistency across varying scene conditions. The large F1.5 aperture is particularly valuable in surveillance applications where 24/7 operation demands reliable performance during dawn, dusk, and nighttime hours.
For system designers prioritizing image quality consistency and operational simplicity, the AL-24B delivers measurable advantages over fixed-iris or standard motor-iris alternatives. Compatibility is limited to Vivotek 1/1.8-inch sensor models, so camera selection should be confirmed before procurement.
