infrared beams are not used as thermal sensors i rl. they are used as motion sensors. infrared detectors are used as thermal sensors. the second the beam is cut off, through glass or solid matter, it would be triggered. the way they used these devices was. clearly. 100%. wrong.i have never complained about the lack of research and effort that went into this show before, even when he's recovering the lost data in 5 seconds on gabrielle anwar's laptop, and without knowing the name of the file to recover, or some sort of data recovery software, you hear him spit out things like "enter the hexadecimal blah blah blah".....total fake jargon....they could have at least tried. or my favorite "we need someone with software that has a linear regression algorithm built into it etc etc......it would still take massive amount of time to adapt the software to communicate with the panel, and they had seconds to minutes.all the inaccuracies, all the things that make you go "why, dear god why, didnt the writers employ ONE single programmer/engineer on their staff, go to the library once a week, or just google it?????" have not made me comment/reply or bugged as this infrared beam fallacy...... I have managed to look the other way and enjoy the show regardless (the man who knows everything, notices all the minor details, doesnt notice a camera in his vent in his secret room?????a camera that is sort of a pinhole camera, but with a larger base and very noticeable????)I will finish the series, but there is a reason this show was cancelled. it wasn't the plot, it wasn't the acting, it wasn't the attempt at the tech, science, and knowledge involved.....it was the lack of research when they actually went in any level of depth. the writers thought they could fake it. it makes me want to find the writers, slap them over and over and over again screaming "HOW DUMB ARE YOU? HOW DUMB ARE YOU?"tl;dr infrared beams detect movement not temperature, only incoming non beamed sensors designed to detect heat alone would the glass trick have worked on. the lack of research is what got this show cancelled because the writers continually tried to fake all the science instead of doing any research whatsoever.

i know right John and Stella would have made a great couple !! they are so on the same wavelength.

lol, I found that ridiculous myself.
