Keep image coverage predictable with a lens module designed for a specific surveillance role. The Hanwha Vision SLA-5M4600Q combines a 4.6 mm fixed focal length with a 1/1.8-inch 5MP CMOS imaging path and an M12 mount, giving integrators a compact optical component for supported Hanwha systems. With a horizontal field of view of 77.9 degrees and a vertical field of view of 57.9 degrees, this module is suited to installations that need balanced scene coverage without the variability of a zoom lens. That makes it a strong fit for monitored entrances, corridors, and other areas where framing consistency matters across multiple cameras or sites. The fixed design also simplifies system planning. Instead of tuning a variable lens in the field, teams can standardize on a known view and build around it. For surveillance deployments that value repeatability, compact integration, and platform-specific compatibility, this lens module delivers the optical precision expected in higher-end Hanwha camera assemblies.
