Hikvision HV1140D-8MPIRA 8MP IR Varifocal Lens

The Hikvision HV1140D-8MPIRA is a professional-grade varifocal lens engineered for demanding surveillance applications. With 8-megapixel resolution and IR compatibility, it delivers exceptional image clarity across dynamic lighting conditions. The 11-40mm focal length range provides flexible scene coverage, while the DC auto-iris mechanism ensures consistent image quality whether monitoring expansive areas or capturing fine details in low-light environments.

Key Features

• 8MP Resolution — High-definition imaging captures critical detail for identification and forensic analysis
• 11-40mm Varifocal Range — Adjustable focal length adapts to varied scene requirements without lens replacement
• DC Auto-Iris — Automatically compensates for lighting fluctuations, maintaining optimal exposure in day/night transitions
• IR Compatible — Optimized for infrared-equipped cameras, extending surveillance capability into complete darkness
• Varifocal Design — Eliminates need for multiple fixed lenses, reducing inventory and deployment complexity

The HV1140D-8MPIRA addresses a critical challenge in multi-scenario surveillance: eliminating fixed-lens limitations. Its 3.6× zoom range (11-40mm) covers both wide overview and medium telephoto shots without optical quality loss. The DC auto-iris mechanism is particularly valuable for facilities with uncontrolled or rapidly changing ambient light, as it maintains consistent exposure without software-based compensation artifacts.

IR compatibility ensures the lens works seamlessly with Hikvision's IR-equipped camera platforms, delivering full nighttime surveillance without separate imaging chains. For system integrators, the varifocal approach reduces SKU proliferation and on-site focus adjustment time, lowering total cost of ownership.
