SUMMARY
Aspheric lenses can effectively narrow the field of view (FOV) for motion detection systems, achieving angles around 20 degrees. Users in the discussion suggest that while Fresnel lenses typically offer a minimum FOV of 30 degrees, aspheric lenses provide a viable alternative. Additionally, employing blocking pieces can also help in narrowing the FOV. Detailed specifications and dimensions of the desired setup are crucial for optimal results.
