TV0550D-4MPIR - Mega-pixel Auto-Iris Lens

The Hikvision TV0550D-4MPIR is a high-performance, 4-megapixel varifocal CCTV camera lens engineered to deliver sharp, detailed optical clarity for advanced surveillance applications. It features a versatile 5–50mm focal length with an f/1.6 aperture, providing a 10x manual optical zoom that allows operators to easily transition from wide-angle overviews to narrow, long-range telephoto shots. Designed for dynamic and unpredictable lighting environments, the lens incorporates a highly responsive DC auto-iris system alongside advanced IR-corrected optics, which automatically maintains optimal exposure levels and completely eliminates focus shifting between day and night monitoring cycles. Supporting up to a 1/2.7" maximum image format sensor, this durable 177-gram lens is equipped with standard locking screws for precise manual zoom and focus tuning during installation, ensuring reliable, high-efficiency performance across a wide operating temperature range (-20°C to 60°C).
