combination a scene can be well lit with IR light that the camera can see but people cannot. This is great for areas
where external lighting is not allowed or there is a need for covert security.
Normal, or visible light, and IR light have different focal points. The camera has 3 IR modes to help optimize focus
capabilities and achieve sharper IP pictures when using these light sources. See the following table for
recommended settings for corresponding IR Switching with IR illumination.
