Answer 2

Hi friend !

Human eye is designed that it can only see the visible region i.e. 10⁻⁶ m wavelength 

The VIBGYOR range is (  10 ⁴ - 10²⁰ ) Hz of frequency 

As This devices are worked on Radio waves which have largest wave length 
i.e. 10³ so we cant see them . 

But cameras are designed on the principle that They can see anything they have no limits actually they just have pixels that can fill anything in pixels 

But our eyes cant make an image on retina far from visible region 

You can see the electro magnetic spectrum . for further details Contact me
