Truvelo IR flash

[puggit]

Sorry - might have been mentioned before...

If you have a Ford Focus with front windscreen demister and switch it on to heat the front screen - is this enough to block the picture being good enough to see who was driving?

The heat is only a few degrees warmer than the surroundings, if it was reaaly much hotter then maybe yes. Some cars have those 1/r blocking screens they may be more effective.

it's not infra red though on the truvelo so it makes no difference

Removing your bonnet and a hot engine however should be like shining a searchlight on the camera. You'd need to know more about how the camera worked and what it is vulnerable to. Any MAD members done a dissection yet?

Wrong type of IR. In the wrong part of the spectrum.
We have Visible IR (ie specs, truvelo etc) and then we have Ir in the thermal part of the spectrum, ie a FLIR camera....it sees thermal emission, not visible to an IR camera.
Sorry guys, back to the ol drawing board...

Ps, Ir visible is around 880 to 1600nm, ir thermal spectral response is 7-12 micron range .

The Truvelo emits Magenta light, which is at the opposite end of the spectrum to Infra Red.

Here is a photo from a Truvelo:
