It's about visual range. Cameras have a value for "max brightness" and "min brightness", facial recognition further narrows that range, where it can work.
The IR LEDs utilize this limited range to "blow out" the pixels in their area with "white/max" informations, overwriting facial info. So you must wear the IR Leds in your face or close by.
That camera may not have an IR filter, and the fidelity hasnto be low... both factors are not present in modern Ai optimized cameras (global shutter, min. 16 bit grayscale brightness only not 16bit divided on RGB, Filters etc.)
You are better off painting your face or printing faces on your clothes.
