This is a creative art project. Obviously, it doesn't work, and cannot work as designed. Most consumer night-vision cameras emit near-infrared light with LEDs at around 750-900nm, which is the wavelength this spaulder is designed to pick up. This is the same wavelength of EM radiation your TV remote uses. If your phone camera does not have a filter for IR light, you can see this kind of radiation as a white glow through your phone.

Cameras generally emit IR only while in darkness. Sunlight, or even incandescent lightbulbs, will emit so much infrared light that any nearby security cameras would be blotted out.

A functional 'security spaulder' device would need to be far more complex. Maybe a combination of IR, network packets, and other indicators would work.
