HD fisheye lens for surveillance cameras providing a full 180 degree panoramic view with support for up to 5MP imaging. Compact M12x0.5 mount and 1.8mm focal length make this lens suitable for board cameras and CCTV modules that use a 1/2.5 inch sensor format. Key benefits Wide 180 degree coverage: Capture large areas with a single camera to reduce blind spots and limit the number of cameras needed. resolution support: Designed for up to 5MP sensors to preserve detail across the panoramic field. Bright aperture for low light: F2.0 aperture allows more light to reach the sensor, improving image clarity in dim environments. Compact and easy to install: Standard M12x0.5 mount simplifies replacement or upgrade of compatible camera modules. Optimized for 1/2.5 inch sensors: Image circle and optical parameters match common 1/2.5 sensor modules for reliable performance. Specifications Focal length: 1.8mm Mount: M12x0.5 Sensor format compatibility: 1/2.5 inch Maximum supported resolution: 5MP Aperture: F2.0 Field of view: 180 degree fisheye projection Intended use: Video surveillance and CCTV camera modules How it solves common surveillance problems Reduce coverage gaps and simplify system design by replacing multiple fixed lenses with a single fisheye for overhead or wallmounted panoramic monitoring. Preserve usable image detail for identification and situational awareness by pairing the lens with compatible 5MP sensors. Improve performance in lower light scenes thanks to the F2.0 aperture, reducing the need for additional illumination in many environments. Practical use scenarios Retail store ceiling installation to monitor aisles and checkout areas with one camera, helping detect incidents and monitor customer flow. Small parking garage or entrance area to provide continuous panoramic coverage of vehicle and pedestrian movement. Conference room or warehouse oversight where wideangle visibility simplifies layout and reduces blind spots for security monitoring. Compatibility and installation notes Requires camera modules that accept M12x0.5 lenses and use a 1/2.5 inch sensor format. Intended for use in video surveillance and CCTV camera systems; verify sensor resolution and physical mount clearance before installation. This fisheye lens provides a compact, resolution option for panoramic surveillance needs, combining wide coverage and compatibility with common CCTV sensor formats.
