Do you see the connection here?

If you watch this documentary below you will see that many of the UFO's are balls of light which are mainly seen by an infrared camera only:

Now when you watch this Unsolved Mysteries report about the Belgian UFO sightings you will see that one of the witnesses mentioning that one of the UFO's morphs into a ball of light:

Obviously there's a connection between these two separate sightings. This cannot be some global hoax?

Does this cloaking ability which most of the times is only visible in the infrared spectrum explain the crop circles and other UFO phenomenon? Does this revelation also open up a new branch in ufology research that will be aided by infrared cameras?

I'm not sure you understand the concept of infrared very well. Infrared light is a spectra of light below that of visible light. UV light is that which is directly above visible light.

We can only see visible light, so the witness who saw a "ball of light" couldn't have had the ufo been in the infrared region, as it would be impossible to see.

I do understand the term infrared. The main connection that I was trying to make here was between the frequent glowing light sightings and the morphing UFO sighting.

The thing is that the glowing lights can not only be seen in the normal light spectrum, but also the infrared spectrum.
