New holster sensor detects when a cop’s weapon is drawn, turns on nearby body cams

By Kelly Hodgkins Published February 28, 2017

Axon is best known for its body and dashboard cameras that are worn by police forces in the US and the UK, but now the company is expanding its law enforcement lineup with the Signal Sidearm: a new gun holster sensor that turns on all nearby body cams when a gun has been removed from a holster.

Despite its name, the Signal Sidearm is not a sidearm itself. Rather, it is a wireless sensor attachment that can be retrofitted to most existing firearm holsters. The sensor detects when a gun is drawn from the holster and uses the company’s Axon Signal technology to alert devices in the area. This alert function turns on the recording feature for any Axon camera, including both body and in-car cameras, within 30 feet of the signaling holster. This simultaneous activation allows officers to record video footage from multiple camera angles, which is indispensable when documenting possible hostile confrontations.

The sensor is powered by a coin cell battery, which is expected to last up to 1.5 years. Because it’s wireless device, there are no cables to worry about, making it both easy to install and a cinch to use in the line of duty. Axon plans to begin selling the Signal Sidearm starting in the third quarter of 2017.

Of course, the Signal Sidearm isn’t the only cutting edge technology designed to protect police officers in the line of duty. Earlier this month, the FCA announced new technology that will protect officers from ambush while they are parked. The Officer Protection Package uses the existing rear park assist systems and the backup to detect movement behind a police vehicle. When movement is detected, the officer is alerted and the car secures itself by locking the doors, rolling up the windows and flashing the taillights.

And that’s just a small sample of what’s out there. Law enforcement agencies all over the world are increasingly turning to technology to solve some of their toughest problems, so don’t be surprised if you see more

The Ioniq 5 is once again eligible for the $7,500 tax credit

2025 Hyundai Ioniq 5

After a brief and confusing absence, the Hyundai Ioniq 5 is once again eligible for the full $7,500 federal tax credit — and this time, it's sticking around (at least for now). So, what happened? Let’s unpack the ride.

The Ioniq 5, a sleek and tech-savvy electric crossover, initially made headlines not just for its design, but for being built at Hyundai’s brand-new Metaplant in Georgia. That domestic assembly qualified it for the EV tax credit under the Inflation Reduction Act (IRA), which requires vehicles to be made in North America with batteries sourced from trade-friendly countries. But early in 2025, the Ioniq 5 vanished from the list. Why? Likely due to its battery packs, which were then still being sourced from SK On’s Hungarian facility.

In Brave New World, the former Winter Soldier apparently retired from being a reformed hero and went into politics by running for Congress. Thunderbolts reveals that Bucky won his election to the House of Representatives. But his stay in Congress was short.

Jeep Compass EV breaks cover—but will it come to the U.S.?

jeep compass ev us newjeepcompassfirsteditionhawaii 4

Jeep just pulled the wraps off the all-new Compass EV, and while it’s an exciting leap into the electric future, there's a catch—it might not make it to the U.S. anytime soon.
This is a brand new electric version of the Jeep Compass, and being built on Stellantis' STLA platform—the same architecture underpinning models like the Peugeot E-3008 and E-5008—it looks much slicker and packs a lot more inside than previous versions of the Compass.
Let’s start with what’s cool: the new Compass EV is packing up to 404 miles of range on a single charge, a 74 kWh battery, and fast-charging that gets you from 20% to 80% in about 30 minutes. Not bad for a compact SUV with Jeep's badge on the nose.
There are two versions: a front-wheel-drive model with 213 horsepower and a beefier all-wheel-drive version with 375 horsepower. That AWD setup isn’t just for looks—it can handle 20% inclines even without front traction, and comes with extra ground clearance and better off-road angles. In short, it’s still a Jeep.
The design's been refreshed too, and inside you’ll find the kind of tech and comfort you’d expect in a modern EV—sleek, smart, and ready for both city streets and dirt trails.
But here’s the thing: even though production starts soon in Italy, Jeep hasn’t said whether the Compass EV is coming to America. And the signs aren’t promising.
Plans to build it in Canada were recently put on hold, with production now delayed until at least early 2026. Some of that might have to do with possible U.S. tariffs on Canadian and Mexican vehicles—adding a layer of uncertainty to the whole rollout.
According to Kelley Blue Book, a Stellantis spokesperson confirmed that the company has “temporarily paused work on the next-generation Jeep Compass, including activities at” the Canadian plant that was originally meant to build the model. They added that Stellantis is “reassessing its product strategy in North America” to better match customer needs and demand for different powertrain options.
So while Europe and other markets are gearing up to get the Compass EV soon, American drivers might be left waiting—or miss out entirely.
That’s a shame, because on paper, this electric Jeep hits a lot of sweet spots. Let’s just hope it finds a way over here.
