In one embodiment the method of detecting the presence of an imaging system producing an invisible illuminator includes introducing a first optical filter capable of blocking energy from an LED infrared illuminator band source and allow energy from broadband visible light source to pass with minimal attenuation; and introducing a second optical filter that permits most of the energy from said infrared illuminator to pass and blocks a substantial portion of said broadband visible light; wherein said filtered LED infrared illuminator and said broadband visible light blink on and off.
