How Well Do Body Camera Work

There'due south footage of Michael Brown at a convenience store before he was shot to expiry and in that location are tweets showing the backwash. In between, there's nothing, other than officer Darren Wilson's retention and alien eyewitness accounts.

Who watches the watchmen? For a lot of people, the answer to that is body cameras.

"It'southward the best bachelor testify that's neutral," Steve Tuttle, vice president of communications at camera company TASER, told The Wire. "It'due south only an observer. The truth is the truth."

Because of the events in Ferguson, more than 140,000 people accept signed the White House petition in favor of creating the "Mike Brownish Law," which would require all police force to wearable torso cameras. The Metropolis of Ferguson has also announced it volition explore the apply of cameras, and major counties accept begun considering the pick.

But before whatsoever of this moves forward, it'due south important to examine the technology itself. The Wire spoke with iii companies designing and making these cameras — Taser, Vievu, and Vidcie — to empathize the inner workings of their possibly game-changing accessories.

The Blueprint

The commencement consideration for all three companies came down to placement — these are wearable tools, after all. Taser's model, the Axon Flex, includes two components: The commencement, a button for the officer to double click so the camera starts recording, and the 2nd, a lipstick-sized camera which would attach to whatsoever headgear or the officer's neckband using a secure magnetic mount.

Information technology's a design meant to protect against error. "The button is raised quite a bit, so you're not searching around for it," Tuttle said. "The double tap is to avoid [beingness] inadvertently clicked."

Vievu, though, took a different arroyo. The device has a slider that turns the camera on, and is mounted onto the officer's chest (which Vidcie does equally well). "The officers nosotros've talked to don't experience comfortable wearing something on their heads for long periods of time," Steve Lovell, Vievu'due south president and C.E.O., told The Wire. "The officer is too robotic."

The Footage

Here's where things get tricky. If a camera is left on at all times, the data accumulates apace (Oakland's police force department, for example, has almost 5 years of data, or 190 terabytes of space, Lovell says), and all camera designers work with sophisticated software that would simply shop what's needed.

The traditional method, used by Taser and Viveu, is to have the officer plough the device on when recording is necessary (a decision fabricated past private police departments and so far), and turn them off when cleared to do so.

Vidcie, a smaller company than the other 2, is attempting a different technique: Their cameras capture feeds, but instead of recording everything, the cameras would work like "little black boxes," Vidcie C.E.O. Romulus Pereira, told The Wire. The video livestreams to the precinct to officers on duty. This makes the officers wearing the devices walking security cameras in a way, with another watching monitoring what'southward being filmed.

"It's a chain of custody that avoids human easily from touching [data] until it gets into a secure concord," Pereira said.

The Storage

Storage is handled past the deject, the yet-quite-mysterious all-encompassing technology that Taser and Viveu primarily use (Vidcie leaves storage options up to individual departments, but as well archives using the cloud). But what makes video taken by law cameras and then different from the information you lot send through social media?

The reply: Access. Taser doesn't incorporate a delete button — "Once it'due south recorded, it's recorded," Tuttle says — information technology encrypts every frame before uploading it to Bear witness.com, Taser's cloud. However, Taser itself tin't run across the videos, and the only people immune to view the footage are verified administrators, ordinarily constabulary chiefs.

It works like a digital bear witness room. People must be verified to admission a video, and then their viewing is recorded — just as yous would to enter prove rooms in traditional police departments. The log also keeps rails of what officers do to the footage, whether they employ tags to it to identify the state of affairs or copy it for their own use. The original video remains saved for a certain number of days determined by the department (typically 30), and the ambassador receives a notification earlier the cloud deletes it.

Same goes for Vievu. People logging into the cloud are credentialed, and all user and file activity is logged. Instead of Bear witness.com, the company uses a software chosen VERIPATROL, which allows departments to establish groups of people to run across the video. As with Taser, Vievu has no access to the videos.

The Sell

The last step for these companies, then, is to help police departments move along and use the technology.

"We're in the 21st century," Tuttle said. "We can do this, and we can do this deeply."

Tuttle went on to name three factors challenging the cameras' widespread use: awareness, change, and budget. The first has inverse with Ferguson, as more and more people understand the possibility of capturing all footage of such a shooting. The second involves the difficulty of rewriting rules in law enforcement. Equally Tuttle notes, Taser's, well, shocking Taser weapons, took decades to attain the bulk of police departments and supercede the traditional batons.

The third is the budget, every bit cameras are expensive, costing upwards of $300 for a single prepare. While Tuttle says the investment would pay off equally law misconduct complaints cost much more to handle, Viveu has begun using a monthly pay policy for departments that cannot order dozens of cameras at once but need them every bit soon every bit possible. In other words, the faster constabulary departments catch up to technology, the ameliorate.

"Law enforcement is nether extreme scrutiny and needs to go along current with the technology out in that location," he said. "It'southward a community transparency tool."
