-- very good to have you how does that work -- I've heard about this sort of stuff and how it matches a database of a bases and I -- -- it's over my comprehension which is not hard to do but but explain how it works out.
Certainly also what happens is is as you process video and -- -- The actual -- -- technology that extracts information from the video.
That information it could be color size shape direction aspect ratio of speed.
It can be things like faces and those things once you have that you can now search on that capability.
It makes the challenge of sifting through.

Guaranteed to be wrong the in the technology is not perfect.
But it what it does -- it -- away just a tremendous amount of information that's not useful.
And -- let you Maryland of parts of information it is useful -- -- -- -- -- -- records.
75 years of video in an hour.
So that you think about wow human effort to go through that kind of video it's it's virtually impossible.
So the fact you know you have we called false positives in the industry -- have false positive.
So you know the bottom line is the here and is exceptional.
And be able look at those pictures are very quickly just saying this is the guy -- -- -- interest or not.
-- should thank you very very much.
-- my pleasure.
