1.8mm Fisheye Lens for 5MP Cameras Overview A compact metal fisheye lens designed for panoramic surveillance. The 1.8mm focal length provides true 180degree horizontal coverage, letting a single camera view areas that would otherwise need multiple lenses. resolution imaging and an M12 interface make this lens practical for a wide range of network cameras and embedded devices. Key benefits Wide coverage with fewer cameras: 180degree horizontal panoramic view reduces the number of devices required and simplifies installation and cabling. definition detail: Supports up to 5MP output at 2592x1944 for clearer faces and license plates in panoramic scenes. Strong compatibility: Standard M12x0.5 thread works with most network cameras, dashcams, and similar devices to lower integration costs. Consistent image quality: Lens design provides uniform illumination and brightness from edges to center, minimizing the typical degradation of traditional wideangle lenses. Durable and precise: Metal construction and sensitivity optics deliver reliable performance in tight or demanding installations. Specifications and performance Focal length: 1.8mm fisheye for super wideangle, 180degree horizontal coverage Resolution support: 5MP output, 2592x1944 Interface: Standard M12 interface with M12x0.5 thread Image formats: Compatible with 1/3inch and 1/4inch CCD image formats Construction: Metal body, designed for stability and longterm use Optical behavior: Engineered distortion for panoramic compression while preserving usable detail and even brightness across the frame Why customers need it Reduces hardware and installation complexity for largeangle monitoring tasks. Enables resolution panoramic imaging where detail and wide coverage are both required. Lowers integration costs by fitting common camera modules and dashcams without adapters. Practical applications Elevator and smallroom surveillance: Captures the entire cabin area with one lens, avoiding blind spots and reducing installation time. Retail and corner coverage: Monitors store corners and aisles with a single camera to cover areas that would otherwise need multiple cameras. Vehicle interior or dashcam use: Fits dashcams and invehicle cameras to record entire cabins or wide road views while maintaining image detail. Compatibility notes Designed to mount on devices with an M12x0.5 lens thread and to work with cameras that accept 1/3inch or 1/4inch CCD formats. Compatible with most network cameras, dashcams, and embedded vision modules that support M12 lens mounts. Installation tips Verify camera sensor format before mounting to ensure correct field of view and focus. Use the standard M12 thread for secure and repeatable installation. Tilt and positioning can optimize coverage in confined spaces to reduce useful distortion while maximizing area captured. This 1.8mm fisheye lens is a practical option where widearea, resolution panoramic imaging is required and compatibility with existing devices is important.
