Does anyone know if speed cameras have Infrared Filters? Answered

Just curious, do speed cameras have IR filters.. is kind of a hard one to test this one, it would involve me driving through them and copping fines to see the pictures.

I have a project in mind that relies on them not have a Filter or a slight filter....

first off i believe that mythbusters will defend the system, they will never tell you the truth.

I thought myself to the same trick to blind the camera with infra red overexposure but what is the frequency?

however, the "flipper " is the safest, as long as you do not get caught.

Hi there, I’m really curious. how did you go with the IR set up ? Did it work in blinding the speed cameras?? I’m thinking of doing a similar thing

If the ones in Australia record video, then they probably don't have an IR filter, at least at night. Video cameras rely on infrared illumination to see in the dark and a filter would prohibit this. If this is the case, an IR filter might be engaged only during the day(think of "Nightshot Plus" on a Handycam).

If they take photos with a flash, then the camera will have a permanent IR filter. Most DSLRs have an IR filter built in.

To the best of my knowledge, speed cameras use TOF (time of flight) to calculate the speed of a captured vehicle.

An IR filter has little or nothing to do with it.

He's thinking of blinding the camera so it can't record his license number.

oh...I see...hadn't thought of that approach...I suppose he could always rig up a flap door that he could trip every time he goes thru a traffic light....

 yeh well i was going to just wire them into the ignition so they are on all the time and since people cant see the light i should be fine in terms of being pulled over... also i believe the law only restricts the use of the microwave bandwidth, used by the speed guns and can be made in to jamming devise (in Australia) not infrared so i should fine in terms of going to jail

omg...your anigif is both revolting and way cool..

interesting solution, although I'm not sure how successful it will be..best of luck. I despise those damned cameras... and it's not because I speed on city streets (I don't as a general rule) but because of what they mean to the long term ideals of liberty and privacy. Ironic how so many of these devolutionary ideas come from members of the 60s gen and their children. doncha think?

If you're thinking of using IR  LED's mounted around the license plate to blind the cameras, don't bother.
Mythbusters tried that one and it didn't fool the camera.

i don't remember that they used IR LEDs, i know the used LEDs

Since Gatzos can take pretty clear pictures through fog, smoke and driving rain, I'd say they do.

 yeh along with driving rain in the dark i thought they might not

but they might have a slight filter on them to filter out some wavelengths of the IR spectrum so id have to get the right LED

well yeh i was thinking of getting about 40 high intensity IR LEDs and mounting them all around the plate then hook them into the ignition, maybe a switch on the dash.

i guess the only way to figure this one out is to test it :S 

maybe ill try with more LEDs... better to be safe than sorry..
