Motorized Focus1/1.7" 12MP 10-50mm Auto Iris Varifocal Lens

This high-definition 5× electric zoom lens features an optical design optimized for the largest compatible sensor size—1/1.7″—and delivers a native optical resolution of up to 12 megapixels. It supports fully motorized zoom and focus actuation, DC-driven automatic aperture control (with optional P-IRIS for enhanced precision), and integrated IR day–night common-focus correction. Crucially, the lens maintains consistent focal plane alignment across both visible-light (daytime color) and infrared (nighttime monochrome) imaging modes—eliminating focus shift during day–night transitions. Constructed with a full-metal barrel and all-glass optics, it is engineered specifically for demanding high-definition applications including intelligent traffic systems (ITS), license plate recognition (LPR), access control gateways, elevated surveillance, and AI-powered analytics cameras. The lens is fully controllable via standard remote protocols (e.g., VISCA, Pelco-D/P) for zoom and focus operations and is compatible with leading 1/1.7″-format image sensors—including Sony IMX415 and OmniVision OS04D10.

Key Features：

1. 12 MP Optical Performance Optimized for 1/1.7″ Sensors
The entire optical path is rigorously optimized for 1/1.7″ image sensors, ensuring high modulation transfer function (MTF) uniformity from center to edge across the full zoom range. This enables exceptional edge sharpness and fine-detail resolution—critical for accurate license plate, facial, and target identification—while effectively suppressing halo artifacts and stray light interference.

2. Motorized 5× Zoom and Precision Autofocus Integration
Provides continuous electric zoom from 10 mm (wide-angle) to 50 mm (telephoto), enabling seamless transition between broad-area situational awareness and long-range detail inspection. Motor-driven autofocus operates synchronously with zoom actuation and supports protocol-based remote control—ideal for integration into dome cameras, all-in-one PTZ units, and AI-enabled edge devices.

3. Adaptive Aperture Control with Optional P-IRIS
Features DC-driven automatic aperture adjustment responsive to ambient illumination levels. An optional P-IRIS module enables digitally encoded, closed-loop aperture positioning—enhancing exposure consistency and enabling tighter synchronization with AI-driven exposure algorithms—particularly advantageous in ITS applications requiring high-reliability capture under variable lighting conditions.

4. IR-Corrected Day–Night Common-Focus Optics
Incorporates chromatic aberration compensation specifically for infrared wavelengths, ensuring precise focus coincidence between visible-light (day) and 850 nm / 940 nm IR-illuminated (night) imaging. This eliminates the need for refocusing during day–night switching, delivering consistently sharp, distortion-free imagery in both operational modes.

5. Large F1.3 Aperture for Low-Light Excellence
Delivers an ultra-bright F1.3 maximum aperture at the wide end, significantly improving photon collection efficiency in low-light and starlight environments. This reduces temporal noise, enhances signal-to-noise ratio (SNR), and improves overall low-illumination imaging fidelity—while maintaining an optimal balance between depth of field and night-vision sensitivity.

6. Industrial-Grade Thermal and Mechanical Robustness
Built with a ruggedized full-metal housing and reinforced optical-mechanical structure. Optical performance remains stable—with minimal parameter drift—across an extended operating temperature range of −20 °C to +70 °C. Designed for sustained, reliable operation in harsh outdoor environments, including roadside infrastructure, border checkpoints, and construction sites.

Typical Application Scenarios：

• Intelligent Transportation Systems (ITS): Electronic enforcement (e.g., red-light running, speed violation), automated license plate recognition (ALPR), intersection monitoring, and traffic flow analytics
• Critical Infrastructure & Security Surveillance: High-elevation HD monitoring in public spaces (parks, plazas), industrial perimeters, and large-scale facility campuses
• AI-Enabled Edge Devices: Integrated vision modules for AI analytics cameras, networked PTZ all-in-one systems, and autonomous mobile platforms
• Machine Vision Applications: Long-range, remotely controllable inspection systems for large-object detection, classification, and measurement
