The SpyFinder hidden camera detector & locator is the most reliable and easy to use technology on the market for making sure that your private actions are not being watched. Its function is based on the principle of optical augmentation. This technical jargon refers to the phenomenon where light reflected from a focused optical system, such as a video camera, is reflected along the same path as the incident light. This means that if a hidden camera is illuminated and viewed with the SpyFinder technology, then a strong reflection from the target camera will reveal its position to the user. The SpyFinder exploits this phenomenon by using a ring of ultra-bright LEDs arranged around a viewing port.
When a user scans a room looking through the viewing port, a hidden camera appearing in the field of view will brightly reflect the light from the LEDs. |
