resolution 4K C Mount lens designed for 10 megapixel surveillance cameras. This 2.8 mm wide angle lens with F1.6 aperture and manual iris gives clear, detail images for CCTV and IP camera systems that use 1/1.8 inch sensors. Key benefits Capture 4Kcapable detail: Optimized for 10 megapixel sensors to deliver sharp images suitable for identification and forensic review. Wide coverage with a short focal length: The 2.8 mm focal length provides a broad field of view to monitor larger areas with fewer cameras. Improved lowlight performance: Bright F1.6 aperture allows more light to reach the sensor, improving image quality in dim environments. Precise exposure control: Manual iris lets installers set the correct aperture for consistent lighting conditions, avoiding automatic fluctuations. Simple integration: Standard C Mount interface and 1/1.8 inch format compatibility make this lens easy to fit to many CCTV and IP camera bodies that accept C Mount. Key specifications Mount type: C Mount Resolution support: 10 megapixel, suitable for 4K imaging Focal length: 2.8 mm Aperture: F1.6 Image format: 1/1.8 inch Iris: Manual Intended use: Surveillance and security camera systems Performance and compatibility notes Use with cameras that support 1/1.8 inch sensors and C Mount lenses to achieve full resolution potential. Manual iris is ideal for installations with stable lighting where a fixed aperture produces consistent exposure. The lens supports resolution recording and streaming workflows used in modern IP surveillance networks. Practical use scenarios Retail and commercial spaces: Monitor store floors and entrances with wide coverage to reduce blind spots while keeping image detail for incident review. Parking lots and perimeter security: Capture larger outdoor areas with fewer cameras; F1.6 helps maintain usable images at night or under low ambient light. Warehouses and loading docks: Provide clear video for inventory monitoring and safety oversight in locations with mixed lighting. Installation tips Adjust the manual iris during installation to match expected lighting to avoid overexposure or washed out images. Confirm camera sensor size and C Mount compatibility before installation to ensure fullresolution capture. This lens is a practical choice for upgrading surveillance optics where wide coverage, resolution, and stable exposure control are priorities.
