Show HN: Security Camera Lens Calculator ( www.jvsg.com/online/ ) We created Security Camera Lens Calculator with 3D graphics(WebGL) and a built-in camera database. It is a web app (Javascript+React) that runs in a browswer or on a tablet or a smartphone. It took our team more than 1 year to complete the calculator. Calculator functions: - calculate pixel density (PPM/PPF) - clearly see dead zones in 3D - check DORI zones (detection, observation, recognition, identification) based on pixel density calculations and IEC and EN 62676 standard. - calculate lens focal length - load a floor map to see camera coverage on your plan - over 9,000 video surveillance camera models embedded in the CCTV Lens Calculator. - 12 languages supported. Today we launched our Security Camera Lens Calculator also on ProductHunt. We would love to get some feedback. Particularly from people using it to solve real world problems.
