4K Motorized Zoom Lens 8–32 mm (4×) for 1/1.8″ Sensors

8-32mm zoom camera module Vari-focal lens F1.3 8MP 4K 1/1.8'' cmos sensor used for video conference camera and facial recognition camera lens module

 

Product Overview

The 1/1.8″ 4K 8–32 mm motorized zoom lens is a professional-grade optical solution designed for robotics vision, UAV gimbals, substation inspection cameras, traffic PTZ, and maritime surveillance. With 4× parfocal zoom capability, it maintains sharp focus throughout the zoom range. Supporting 4K motorized zoom lens 1/1.8 sensors, this lens combines low distortion, high MTF, and IR-corrected options for both day and night operation.

Its ruggedized design makes it suitable for outdoor and mobile applications, while flexible control interfaces (PWM/I²C/UART) ensure seamless integration into industrial and embedded systems.

 

Product Advantage:

1, 4X High Speed Motoried Optical Zoom 8-32mm

2, High Resolution 8MP 4K Zoom Module for High Speed IP Security Camera

3, High Speed AF Auto Focus Zoom Camera Module

4, Large Format to  1/1.8'' Cmos, excellent optical performance

Application Scenarios

• UAV Gimbal Zoom Lens Long Range — for wind turbine, bridge, and transmission line inspection.
• Substation Inspection 4K Zoom Lens — detail recognition for equipment monitoring at distance.
• Traffic PTZ 4K Motorized Lens — high-speed vehicle identification and license plate capture.
• Robotics Vision Motorized Focus Lens — zoom in for detailed inspection, zoom out for navigation.
• Maritime Surveillance Zoom Lens 4K — monitor ports, ships, and offshore platforms.

 

Case Study: Smart Substation Monitoring (USA)

“We deployed the substation inspection 4k zoom lens in our AI-enabled monitoring cabinets. The lens’ ir corrected zoom lens 850nm 940nm option provided consistent focus under both visible and NIR lighting. Engineers now use it to track insulator degradation and overheating spots without deploying handheld scopes. Its 8–32mm c-mount motorized zoom and programmable I²C control allow our system to capture both wide context views and detailed close-ups automatically.”
