Get broad coverage without adding complexity. The Hanwha Vision SLA-2M2802D is a 1/2.8 in fixed focal lens with a 2.8 mm optic and a 107.4° horizontal field of view, built for surveillance deployments that need stable, repeatable framing. In environments such as lobbies, retail floors, loading areas, and building entrances, a fixed lens can be the right choice when the goal is dependable scene capture rather than adjustable zoom. This lens supports efficient system design because the field of view is known and consistent from day one. That makes camera placement easier to plan and reduces the need for post-install tuning. For teams standardizing on a wide-angle view, the 2.8 mm focal length provides a practical balance between coverage and clarity. It is a straightforward professional accessory for installations where the value comes from reliable optics, not unnecessary complexity.
