Yes I have seen this young ladies videos on thermal cameras.
Understandably she is having to guess about some aspects of the cameras design. Hope she found the manual, it is not that hard to find once you know FLIR bought AGEMA
To cover some points she raised.
1. The 400 series is basically an adaption of the earlier 870/880 cooled cameras. The width and length are dictated by the familiarity of the designers with these tripod mounted cameras. This is sadly why the 400 series are ugly ducklings and not very ergonomic. I have resisted adding one to my collection due to their bulk.
2. The SPRITE detector is cooled to only -70C and not the -196C required by Liquid Nitrogen cooled cameras. If she tries to open the Peltier cooling assembly that resides in a Dewar she will destroy it !
3. The spinning sound on power off is not a hard disk, but the rotating mirror spinning down. It spins at 24K RPM ! And remember it is in a vacuum.
4. As she discovered, the files produced by this camera were read by dedicated AGEMA software. Each camera manufacturer used their own proprietary file format.
5. The young lady was searching for lenses when she found the camera. She makes no mention of the fact that there are MW and LW AR coated lenses. I hope she understands the difference between them if she is looking for lenses to work at LW.
I attach a picture of the AGEMA 880. It is basically turned upside down in the 400 series. The processing electronics that are an external unit on the 800 series is then bolted on the rear of the imaging section in the 40@ series.
I also attach the 'cutaway' view of the 880 camera.
