IN car signal blocker

Our Take

The channel behind this video, Digital ID, Mass Surveillance and Digital Currency, has built a catalog of 400+ videos poking at everything from digital currency to biometric ID schemes, and this one dips into the DIY-countermeasure corner of the surveillance debate: a signal blocker you can run from inside your car. We appreciate the instinct — people are rightly anxious about being tracked everywhere they drive — but it's worth being blunt about the practical reality here in the US. RF jammers are illegal under FCC rules, full stop, and ALPR cameras like Flock Safety's don't even rely on a wireless signal from your vehicle to work. They're optical systems reading your plate, so a jammer aimed at cell or GPS frequencies does nothing to stop a camera from photographing your plate, timestamp, and location as you pass.

That gap between the gadget and the actual threat is exactly why this kind of surveillance keeps expanding quietly: people assume there's a clever technical workaround, while the real fight is about whether these cameras get installed on your street in the first place, who can access the data they generate, and whether your city council ever had a real public vote on it. Jamming your own signal also does nothing about the thousands of networked cameras already logging every plate that drives by, pooling that data into a searchable history of your movements that police departments, private companies, and sometimes Flock itself can query.

If you want to actually do something about this, start by seeing what's already watching you. Check our camera map to find ALPR locations near you, and head to our take-action page for real, legal ways to push back — public records requests, city council testimony, and organizing with neighbors who care as much as you do.
