Products/Methods for Protecting License Plates from Cameras/Readers/ALPRs

Using fake plates that are from a similar make and color is probably more safe than any fancy IR blocker or glancing spray. Combine this with a plate changer should be a better choice.

Agree with Venom a CLONED plate would be safest but more illegal.

Find an identical match car, same model, make, year, color, trim, etc. same exact type of car. Clone its plate and Tag.

Just think though... if your decoy clone plate, and the real cars plate... come up on the liscence plate readers at different areas of the city, at the same time. They will know one is a fake/copy. So use it sparangly/little, and change it frequently. Just need raised letters for those plate numbers...

From my reading, they take a lot more notes than just the license plate. You will have to make your car as factory fresh as possible. Bumper stickers, window tint, damage, tire marking, accessories, etc are all claimed to be logged and used to a build a profile by these things.

I am wondering if theres something that can be used with a legitimate plate, that could potentially be applied and removed, I know 3M and a few other companies have tons and tons of different options.

This is for your grandmother, who doesnt want her license plate read by a camera, but also doesnt want to bump it up from a fine to a felony for no reason.

I am talking about a solution for the everyday person that sees cameras popping up in their community and want a simple, maybe not 100% working, but good-enough method to feel safer driving around town.

This person also does not want to alter their vehicle in a way that would cause them anything more than maybe a ticket and a fine. Low-risk options.

Genuinely, this is the scenario, I do consulting on occasion.

I heard a thin layer of mud/dust works to fuck up the IR cameras... And could very easily be accidentally there.

It's all about the reflection signature :)

I figure, you could put some mud/dirt in-between license plate and an IR blocking film for day-time protection, and IR blocking for night time. I have compiled a list of different manufacturers and information.

Regarding the use of IR-blocking films to obscure plates from Flock cameras - while these films are primarily marketed for heat reduction, they can interfere with IR illuminators used by LPRs. However, note that many states require plates to be visible to the naked eye, and visible-light cameras might still read them. Also, some films are specifically designed to transmit IR (like the 3M Sensor Camouflage), so choose carefully.

Specialized & High-Security Films

Note: these may have specific IR transmission/reflection properties for counter-surveillance.

• []Signals Defense IR Film - Protects against eavesdropping and IR laser microphones.
• []NASA-developed IR Blocker - Designed to reflect up to 97% of heat.
• 3M Sensor Camouflage Film - Specifically designed to transmit IR to protect cameras (this would block IR → this would not block IR, so avoid for LPR obscuring).

Remember: applying film to license plates is often regulated – check your local laws before attempting. For Flock specifically, they use both visible and IR, so a complete block might not be effective against all modes.

So the way the cameras read plates is by the reflection on them.

If they're not reflective, they don't reflect IR. That's how the films work. They're basically matte clearcoat

But you can get in to trouble for intentionally tampering with government documents.

If you have a thin layer of dirt/oil, probably not easy to say it's intentional

I 100% agree, if you google it right now there's a ton of companies basically re-selling these different products, or making "proprietary blends" and selling it for a hundred dollars, insane.

You have probably made the most reasonable post regarding plausible deniability. I am wondering where the line is drawn, and what becomes obvious/easy to detect.

I don't think theres a perfect solution yet, but people are not happy about flock and the whole push for community cameras etc. I think this will become a growing threat/topic for people worried about operational security where these cameras are deployed, rightfully so. Hell, even regular citizens are livid about the privacy concerns etc.

If you're gunna go out and do this, you better have plausible deniability or you are cooked.

Also, if the things only pick up 3 letters, I don't think the shit is intelligent enough (yet) to fill in the blanks

I too, have given this thought.

All it takes is one prick cop to say you have something intentionally on the license plate in order to evade police detection for a mountain of shit to pile up on you.

I'm almost certain some matte clear coat would work just as well. I'm almost positive that's all these expensive products actually are...

And tampering with your plates doesn't seem like a good idea, unless it's with something that looks like dirt/dust/road grime that made it's own way on there while driving

Not sure how a reasonable person would explain away some clear coat though.
