Wide Angle Fisheye Security Camera Lens — 5MP, 185° view, 1.7mm focal length, F2.0 aperture, C‑Mount compatible Why choose this lens Capture an ultrawide field of view with a single camera. The 185° fisheye design reduces blind spots and lets a single security camera monitor larger areas than a standard lens. Designed for up to 5MP sensors so your camera can deliver detailed, resolution images across the entire scene. Fast F2.0 aperture improves light gathering compared with slower lenses, helping maintain usable image levels in dimmer environments without adding artificial illumination. C‑mount compatibility provides a straightforward mechanical fit for a wide range of security and industrial cameras that accept C‑mount optics. Key features and attributes Optical type: Wide angle fisheye lens engineered for panoramic coverage and strong peripheral viewing. Resolution support: Optimized for up to 5MP imaging sensors. Field of view: 185° nominal diagonal field, ideal for ceiling or wallmounted surveillance that needs maximum coverage. Focal length: 1.7mm for extreme wideangle capture and characteristic fisheye perspective. Aperture: F2.0 for improved light transmission and better lowlight performance compared with smaller apertures. Mount: C‑Mount compatible for secure, repeatable attachment to cameras with C‑mount interfaces. Use with standard security camera housings and mounts; may require software dewarping for rectilinear or panoramic reprojection. Practical benefits — how it solves common problems Fewer cameras, lower cost: Cover wide areas such as lobbies, retail floors, or parking entrances with a single camera fitted with this lens, reducing the number of cameras and cabling required. Minimize blind spots: The extreme 185° view captures far more of the scene than standard lenses, helping to ensure critical zones are not missed. Better performance in low light: The F2.0 aperture enables stronger light capture to preserve image detail where illumination is limited. Flexible deployment: C‑mount compatibility makes the lens suitable for many security and industrial camera platforms that accept standard C‑mount optics. Use cases Retail store floor monitoring: Mount on the ceiling to cover a large sales area and reduce blind spots, enabling fewer cameras to monitor aisles and checkout zones. Building lobby or reception surveillance: One fisheyeequipped camera can capture visitors, entry points, and seating areas for continuous situational awareness. Perimeter or parking area overview: Provide wideangle monitoring of entrances and drive lanes where broad coverage is more valuable than isolated closeups. Installation and integration notes Fits cameras with a C‑mount interface; confirm the camera accepts C‑mount lenses before installation. Fisheye optics produce curved, distorted images by design. For rectilinear views or stitched panoramic outputs, use camera or VMS software that supports fisheye dewarping. Adjust camera position and mounting angle to balance coverage and detail in priority areas (for example, slightly offset from the exact center to emphasize entrances or counters). What you get A purposebuilt wide angle fisheye lens delivering 185° coverage, 1.7mm focal length, F2.0 aperture, and C‑mount compatibility for up to 5MP imaging systems — designed to maximize coverage and improve situational awareness in security installations.
