I watched the uploaded video, and it is great to see these technolgical advancements in equipment.
In the hands of these very adept camera specialists, the end product to be viewed is a exceptional visual record of a activity in a habitiat, that the usual observer would be oblivious to.
Any individual that has a IR Camera can achieve some of the nightime effects seen in the video, by using a LED IR light panel.
In a discussion I had a few months back whilst visiting a Company that produces IR Converted Camera Bodies, we spoke about their LED IR light panels
and it become appearent they were being produced foor the professional end of the market, to achieve the end viewing experience seen in the video.
