This is a little background that shows beyond normal installed Flock ALPR cameras, they can put up these temporary cameras camouflaged as traffic cones. This leads to tips from feds to local law enforcement for vehicles that fit a trafficker pattern, with the local police or sheriffs then looking for a reason to pull the vehicle over, conduct a roadside interrogation, bring in a dog for reasonable cause to search the vehicle… The reason local law enforcement is so willing to violate citizen’s rights is the asset forfeiture that will result. Though they’re also going to be paying out in lawsuits for illegally detaining citizens for illegal searches, and in one case they’re also deceptively signaling the dog to indicate drugs.

Motorists traveling remote stretches of Arizona highways may be under unseen watch, as ordinary-looking traffic barrels have been revealed to house sophisticated camera systems.
A viral video showing yellow construction barrels equipped with camera lenses has sparked widespread attention, highlighting a covert surveillance effort by federal authorities.
According to a report from Blaze Media, the disguised devices are Automated License Plate Reader (ALPR) cameras deployed by U.S. Customs and Border Protection (CBP) along key routes.
In one instance captured on video, a driver who pulled over near U.S. Route 60 east of Apache Junction — more than 100 miles from the U.S.-Mexico border — noticed slots carved into the barrels for multiple lenses pointed in both directions, with power sources extending into the distance.
The barrels blend seamlessly with standard construction equipment, complete with solar panels positioned nearby for power. Similar setups have appeared in orange traffic cones, speed trap signs, and other roadside markers.
Arizona Department of Transportation officials previously urged CBP to discontinue the practice, concerned that the camouflaged units could confuse drivers.
CBP has employed these systems since at least 2017 to monitor smuggling routes and disrupt criminal networks. A 2019 permit document detailed the setup: “USBP monitoring equipment will be placed in the barrel and weighed down by sand. Barrel camera will have a power supply with solar panel placed thirty feet from the white line [at the road].”
The agency describes its approach as “complex and relies on a layered mix of personnel, technology, and infrastructure to detect illicit activity while supporting lawful trade and travel.” It relies on technology “often the same systems employed by state and local law enforcement nationwide.”
Companies such as Flock Safety, Rekor, and Vigilant Solutions supply many of the ALPR units, with thousands deployed across the country. CBP has not disclosed exact numbers or locations, citing national security. The cameras are typically removed once operations in an area conclude.
