Ok, that was pretty interesting.
 
2013-10-28 04:55:35 PM  
That was neat. Is that security camera infrared?

Yes. And there's a good chance it was manufactured at my workplace.

Did they remove the spider or move the camera? It seems pretty obvious that you can't leave it there unless you want to later put the spider on trial for it's crimes.

CSB, seriously, this kind of tech intrigues me although I understand little of it.

Heh.

Seriously, though... the technology is so sensitive now that if you put your hand on a wall for a few seconds, a decent IR camera will show the handprint as a temperature difference... and can still detect the temperature difference several minutes later. Walking around in a neoprene suit to match the ambient temperature would have to be accurate to a minimum of 3 decimal places.

Looks like a regular digital sensor with no IR filter, and an IR light source (which may just be an incandescent bulb).

I believe you might be confusing IR cameras (which this was) with thermal imaging cameras, which this was not.

You believe incorrectly. I'm well aware of the difference, but they both work on the same basic principle, and a well-calibrated IR camera can pick up extremely subtle differences in temperature.

You can block your heat signature with a mylar foil blanket though.

This is one case where you really don't want to see the original,

Spider in front of Dahua IP camera
http://www.youtube.com/watch?v=innniUIGpII

because it is 1:28:40  long. Though that link can give info on where and what sort of camera.

Insulation is nice, but good luck not leaving a temperature differential with your footprints (the friction on the ground just from walking is detectable), or your breath escaping not making a heat cloud, etc. The problem with all the thwarting efforts is making them self-contained. Unless you feel like risking suffocation, or going through such incredible containment that you're basically hovering around in an insulated space capsule, there's going to be a leak somewhere, and the detectors can spot them.

100% foolproof? No. But the effort required to thwart generally outweighs the benefit, and the stronger the security needs (and therefore more you're willing to pay), the more insane the tech gets. We sell units that can spot a field mouse at 2 miles.

Ah, Dahua IR home-grade. Low-end, but useful as a kind of modern night-vision. That's a pretty nice image they're getting out of their unit.

I work for FLIR. The stuff we make starts at police-grade, and goes up to where you would probably expect (and then some).

We're looking for more in-roads to the consumer marketplace. Expect to hear more from us soon. =D

The false positive rate would be high for something so sensitive.

Not to change the security-cam train of thought BUT, well, here's my vid of a spider in my backyard and her Giganto Web. It lasted for a long time, too.  It's not long and you can fwd. through it to get the jist:

omnibus_necanda_sunt: The false positive rate would be high for something so sensitive.


There are, however, software solutions for minimizing those, and they're most definitely usage-dependent. With the ultra-sensitive systems, the customers are basically getting a unique snowflake of a system, tuned to their specific norms and tolerances. If they need to detect a gas cloud that's .01+/- degree from norm within a given area, but don't need to worry about the occasional cockroach that skitters by, we can make that happen.

No they don't work on the same principle however the point is that this is an IR camera image (reflected light) and not a thermal image (temperature differences picked up on a sensor).

I realize you work for FLIR, but I work with your gear. This was IR.

Then stop posting and start putting some HUD projected night vision in cars, would ya? We've had the tech for quite a long time now. It's well overdue.

So much material comes out of that one animal's tuchas. It builds that whole web out of what it sharts out in one sitting. That's some amazing efficiency with materials, nature. Seriously.

Your tech is useless, I can always switch to UV sensors and see you walking between those carcasses.

I'm amazed at the construction techniques shown by a bug.

First a few of the easy radials.  Then, using those as support, fill in the rest of the radials.

A coarse spiral installed in a hurry, just to keep everything in place.  With that in completed, and using it for support, fill in the rest of the spiral.

The web is its own rigging during construction.

This is a *bug*, using the same techniques humans might use if they had to build a similar structure over a large area.
