Key Features

Wide Application Coverage

Horizontal FOV from 137° ultra-wide down to 51° telephoto, suitable for indoor monitoring, corridor observation, and long-range detection scenarios.

Optimized for 1/2.7″ Sensors

Designed for mainstream sensors such as SC3235, offering high resolving power with controlled distortion across the frame.

Standard M12 × P0.5 Interface

Fully compatible with the NE301 onboard lens holder, enabling fast lens swapping and easy integration during prototyping or deployment.

Industrial-Grade Optical Design

Precision lens structures (2G3P / 1G3P / 4G) ensure thermal stability, mechanical reliability, and repeatable imaging performance.

Manual Focus Adjustment

Focus can be fine-tuned by rotating the lens, simplifying calibration during installation and system setup.
