Hikvision HV3816D-8MPIR 8MP IR Vari-Focal Aspherical CCTV Camera Lens
The Hikvision HV3816D-8MPIR is a professional-grade 8MP vari-focal CCTV lens engineered for high-performance surveillance systems requiring flexible coverage, exceptional image clarity, and reliable infrared compatibility. Featuring an advanced 3.8-16mm focal length range with DC auto iris control and aspherical optics, this CS-mount lens delivers superior image quality across diverse lighting conditions and monitoring scenarios.
Key Features
- 8-Megapixel Resolution: Captures fine detail and enables digital zoom capabilities without significant quality loss, ideal for identifying subjects across extended surveillance areas.
- Vari-Focal Design (3.8-16mm): Adjustable focal length provides a diagonal field of view ranging from 123.9° (wide) to 33.5° (telephoto) on 1/1.8" sensors, or 115.6° to 31.3° on 1/1.2" sensors, accommodating diverse installation requirements.
- DC Auto Iris: Automatically adjusts iris aperture to maintain optimal exposure and contrast across changing lighting conditions, preserving image quality throughout the day and night.
- Infrared (IR) Compatible: Fully compatible with IR-enabled camera sensors, enabling effective surveillance in complete darkness and low-light environments without visible light requirements.
- Aspherical Optics: Minimizes spherical aberration, coma, and distortion, delivering sharper, more uniform images with reduced edge degradation—critical for professional security applications.
- CS-Mount: Industry-standard mount compatible with a broad range of professional surveillance cameras.

Applications
Ideal for retail environments, transportation hubs, perimeter security, industrial facilities, and critical infrastructure where variable zoom coverage, low-light performance, and image precision are essential. The vari-focal capability allows single-camera solutions to replace multiple fixed-lens installations, reducing hardware costs while improving flexibility.

The HV3816D-8MPIR represents a practical choice for integrators seeking a mid-range vari-focal lens with solid IR performance. The 4.2x optical zoom range (3.8–16mm) and 8MP resolution balance flexibility with practical deployment scenarios. Aspherical design is a notable advantage, reducing edge distortion common in standard vari-focal lenses.
The dual sensor compatibility (1/1.8" and 1/1.2") indicates broad camera pairing options. DC auto iris control ensures reliable exposure management in mixed lighting, though users should note field of view varies between sensor sizes—careful selection during camera pairing is necessary. This lens suits applications where fixed-focal alternatives prove limiting but ultra-premium zoom performance is not required.
