Maintain clear coverage across entrances, corridors, and open areas with a lens built for variable surveillance demands. The Hanwha Vision SLA-M2890DN combines a 1/2.8-inch image circle support with 3 MP resolution handling, so it can keep pace with modern IP camera deployments that need sharper detail than basic analog optics can deliver. Its 2.8-9.0 mm vari-focal range gives installers room to balance wide-area monitoring against tighter subject framing during commissioning. Auto DC iris control helps the lens respond to changing light conditions, supporting more consistent exposure across day and night scenes. CS-mount compatibility makes it a practical fit for supported camera housings and modules in professional security builds. For teams standardizing on Hanwha Vision hardware, this lens is the kind of component that reduces compromise at the edge. It is designed for deployments where image quality, field-of-view control, and installation flexibility matter more than lowest-cost optics.
