Video

Very surprised that you haven't patented this for Counter-Counter Infrared missile tech. Aim-9xx systems get spoofed all the time, but with your tech, you could have pre-programmed algorithms and databases of existing world wide flare spectrums so you in theory would create a missile that could not be spoofed. Yes? Wonder if you could even counter stealth tech, by identifying contrails at the higher and much colder temperatures where airstreams would be warmed by hot engine exhaust, in effect a visual cross section via lasers to detect air density could allow one to even see stealth contrails. Yes?

Great useful

Hi there..I don't hear any explanation about this video. What is it about??

What size of structure or pipe is considered as obstruction? Will it change with the size of target fire

Would like yo have a free trial and would like to know more about the Software.

are you Irish? nice accent tho

I guess the most interesting part of this test is that minor contamination of the optics has little effect on detector range. The FDS301 works at visible wavelengths, but otherwise it detects brightness and flicker like any other optical detector. Water is transparent to visible light of course. Flicker frequency is barely affected by moderate contamination. Ironically, the thing that contamination _does_ affect quite quickly is the mirror used by many detectors (not the FDS301) to perform an optical verification test! If it didn't have the OV test then the detector would be fine in wet weather - but many aren't. But, it's just an automatic thing with most detector buyers - does it have an optical verification/integrity test?

Not quite sure what this one is supposed to show. Getting a lot of suspicious fires at your place of business? Look for a culprit wearing red ovies and carrying a gas wand! Our FDS301 detector can get you the video evidence, so don't worry about industrial tribunals.

I was there! What you're seeing is a pit the size of an public swimming pool filled with LNG and then some poor guy set light to it with a hot wand, before running for his life in heavy US style firefighting clothing. The camera is 32m from the fire, which is just getting started. I had to be there to kick off the recording and the heat was astonishing. I started the recording and then I too ran to join the crowd of people sheltering at 50m + !

Yes, it's a pity no explanation was provided. The video is demonstrating that the flame detector inset on the left can be blinded to fires if it has a modulated heat source in its field of view. You'll note that an "easy test fire" is burning in plain view but the red LED on the detector never turns on. The demonstration used a rotating chopper in front of an electric fire, but in real life this is known to be a problem with modulated heat sources such as steam plumes, air conditioning vents, or simply people walking past a metal object on a sunny day. To prove the point, at 0:34 the chopper is stopped (the fire keeps burning), and the detector instantly goes into alarm.
