The light that blocks filming,
An anti-recognition lighting solution that blocks illegal filming and protects privacy
Next-Generation Security Lighting
Next-generation security lighting that blocks filming and protects information
LIGHT SAVER is a special lighting that uses Spresto Co., Ltd.'s unique shooting interference lighting technology. It looks like ordinary lighting to the naked eye, but when captured by a camera, it is captured distorted into a striped pattern of various colors. This blocks corporate confidential information and personal privacy information that may be leaked by filming production processes or private life in advance, and is an intelligent anti-recognition security solution that prevents illegal filming.
Thousands of Hidden Crimes, Every Year
An annual average of 7,000 illegal filming crimes
Over the past 10 years, illegal filming crimes have averaged more than 7,000 cases annually.
Among them, places classified as “others” account for the highest share, targeting everyday spaces such as restrooms, changing rooms, accommodations, and offices.
These numbers reflect only detected cases, and considering unreported incidents, they represent just the “tip of the iceberg.”

The current inspection-based approach has clear fundamental limitations in detecting covert and sophisticated crimes.
Even now, filming crimes exploit the gaps between inspections to leak corporate secrets and violate public and personal privacy.
While filming devices grow smaller and methods more cunning, our response remains limited to manpower-driven periodic inspections. It is time to establish a “technology-based continuous security system” that can protect sites around the clock and respond instantly—for corporations, the public, and individuals alike.
