Body-worn cameras will help "to get better convictions" because the filmed evidence against them will be robust, the head of the Metropolitan Police told Good Morning Britain.
Bernard Hogan-Howe said some evidence was "really hard to capture" with a written statement and providing film would help the victims of crime.
"Secondly, it helps to get better convictions because it is such compelling evidence and quicker because often people will plead guilty when they know that sort of evidence is against them."
Met Police Commissioner Bernard Hogan-Howe has told UK Editor Lucy Manning that he cannot judge if the force is still institutionally racist as it is for others to decide and admitted that if that is still how the police is seen then they must be:
The Met Police Commissioner has said that the force have tried to improve their relations with the black community in London.
Sir Bernard Hogan-Howe said: "Over the last couple of year, we've done an awful lot to build the trust of the black community. We've reduced our stop and search by about a third.
"We've actually improved our effectiveness of stop search and we've also made sure that we've had less complaints - that was a real issue around the time Mark Duggan was shot."
Met Police Commissioner Sir Bernard Hogan-Howe has stood by the conclusions of the Mark Duggan inquest.
When asked by UK Editor Lucy Manning if he felt the Duggan family are owed an apology he said: "I'm not going to talk about apologies. I think the only thing I can do is respect the outcome of the jury's verdict, clearly the family still has concerns and are asking questions."
He went on to say that although he was not worried about trouble on the streets of London, "we'd be foolish not to at least consider the possibility."
UK Editor Lucy Manning has said the Met Police Commissioner Bernard Hogan-Howe stood firm on the conclusions of the Mark Duggan inquest:
Speaking after the verdict of the inquest into police's lawful killing of Mark Duggan, the Met Police Commissioner Bernard Hogan-Howe has admitted: "We do have a particular concern about our relationship with younger members of the black community"
Met Commissioner Sir Bernard Hogan-Howe has confirmed that he will run a trial in which firearms officers will wear video recorders "to see if this is an effective way to record evidence and ensure public confidence".
He also said he would be meeting some of London's political representatives and community leaders from Tottenham later today.
The purpose of the meeting is "to discuss how the Metropolitan Police can build better relationships for the future," he said.
Metropolitan Police Commissioner Sir Bernard Hogan-Howe has said the Mark Duggan case shows that the police "need to do more, much more, to improve our relationship with black Londoners".
In a statement released after the conclusion of the inquest into Mr Duggan's death, he said the case had led to a "significant reduction in trust" between London's black communities and the force.
Firearms officers will start to wear cameras in an attempt "to increase transparency", the Metropolitan Police Commissioner has said.
Sir Bernard Hogan-Howe made the announcement in the wake of the Mark Duggan inquest, saying:
"I want our officers to be able to be open when it comes to the investigations that follow these events. In pursuance of that we're going to ask them to wear video cams so we can record this type of incident."
The plebgate row has clouded the public view of Scotland Yard and has taken too long to deal with, Britain's most senior police officer has admitted.
Speaking to Nick Ferrari on LBC this morning, Metropolitan Police Commissioner Sir Bernard Hogan-Howe said:
"During the time this thing has been an issue, the Met has been performing better than ever. We've just got to live with the reality - the newspaper headlines, the fact that you're talking about it, clouds the fact that crime's coming down at its fastest for 30 years.
"This issue's got to be resolved and we've got to deal with it."
He added: "We're all eager to see the outcome of this inquiry and that we get back to some kind of normality, because I think it's not good for the police and it's not good for public confidence.
I'm determined to get to the bottom of it, we've got a thorough investigation and we really now have to await the outcome of that."
