20 cameras and 50 cameras are not 4000. Body cameras are used by special units, but have specific applications, not suitable for general used for reasons already outlined.Google is your friend Blackrock. You really didn't think this one out before you answered did you? Of course you didn't.

The U.S. Department of Justice has granted $500,000 to the Phoenix Police Department and the Arizona State University College of Public Programs to buy 50 video camera systems that police officers will wear on their uniforms.
> Ring is part of a growing number of police officers across the country wearing body cameras. He's also a member of the only police department in South Hampton Roads using the cameras, although the Suffolk Police Department just bought 20 cameras through a grant.
Ring is one of roughly 90 Chesapeake officers assigned a body cam.
> BAINBRIDGE ISLAND, Wash. -- Four Bainbridge Island police officers are now wearing a video camera on their chest.
Commander Sue Shultz says the cameras document encounters with the public and provide evidence
That was all just from the first page I looked at.
There are also legal problems as some states have very restricted laws on the books making the recordings challengeable and then there are the privacy problems for law abiding citizens. All the problems are not just technical.
Maybe you should have read further in to what you looked at.
Here's points raised in some of those pilot projects in Canada.
The widespread use of cameras by police in Canada has raised the ire of civil groups concerned about invasion of privacy. Nathalie Des Rosiers, general counsel with the Canadian Civil Liberties Association, said the video should be available to those who are recorded under freedom of information, which Saskatoon's police service isn't covered by.
Des Rosiers said there should be protocols established for the safekeeping of the data. If the cameras are triggered by police officers, even through emergency systems, there is a bias, she said.
"They do not completely help in terms of ensuring there is transparency," Des Rosiers said. "Before the cameras are on, it does not prove the police are not abusing anybody's right."
While police forces across Canada are equipping officers with cameras clipped to bike helmets, lapels and vests, police in Saskatoon are still focused on getting the in-car camera program off the ground before forging ahead, Engele said.
In Victoria, police tested six mini-cameras mounted on bike helmets or sunglasses two years ago. The cameras proved successful in identifying a suspect in a violent assault during a rowdy Canada Day. But the program wasn't expanded after the pilot program despite the cameras being trumpeted as less costly and more versatile than dashboard cameras.

or how about his one;
One of the biggest issues with the body cameras, which came up at a committee hearing in Olympia last week, lies in the state’s complex disclosure laws, which could prevent police from releasing videos recorded by cop cams until after the statute of limitations on criminal and civil cases related to the recorded videos have passed. That could make it nearly impossible to obtain the videos for use in a civil misconduct lawsuit against the police department.

Does the same problem exist in Canada? Let's have the lawyer talk about that one.
