Theia SL410P 1/1.7" 4-10mm F1.4 P-Iris Varifocal CS-Mount Lens, IR Corrected, 4K Ultra HD, 12MP Rated

Designed for professional security and surveillance installations, the Theia SL410P varifocal lens delivers ultra-high image quality where detail matters most. Built to resolve true 4K/12MP images on 1/1.7" sensors (or smaller), this lens makes license-plate capture, facial recognition, and perimeter inspection more reliable. The 4–10 mm focal range provides flexible framing to adapt rapidly between wide-area monitoring and tighter scene coverage, while the bright f/1.4 aperture improves low-light sensitivity and creates a cleaner image under challenging lighting. IR-corrected optics maintain sharpness and color fidelity for Day/Night operation when paired with IR illumination. Its compact CS-mount footprint fits easily into 4" domes and bullet camera housings and the built-in photo interrupter supports precise P-iris control for consistent exposure and depth-of-field. Ideal for retail, transportation, campus, or municipal surveillance projects, the SL410P balances exceptional optical performance with straightforward integration.
