OKS-3651‑A4‑650 is a high‑performance 4K 8MP low‑distortion M12 lens specially developed for network IP cameras and AI intelligent monitoring systems. Built with premium 4G2P+IR optical structure, it supports 1/2.5",1/2.7",1/2.8" image sensors to output sharp 8MP 4K high‑definition pictures. The ultra‑low‑0.5% TV distortion realizes human‑eye‑simulation undistorted imaging, effectively reduces picture distortion, guarantees high accuracy for AI object detection, human‑body recognition and perimeter alert algorithms. CRA<16.7° ensures uniform brightness across the whole image, greatly improves anti‑glare capability under complex light environment. F2.4 aperture delivers good low‑light imaging for day‑night 24/7 surveillance. Focus range covers 0.6 meter to infinity, satisfies both near‑distance and long‑distance monitoring requirements. Compact mechanical dimension fits most network camera housings. Wide temperature‑40℃~+85℃ supports stable continuous operation for indoor‑outdoor IP camera, intelligent security device and machine vision equipment mass production.
