Why the Hong Kong police force are using Reveal body cams


Hong Kong police force (HKPF) have been using Reveal RS3-SX body cameras since their first field trial in March last year. The HKPF believes that Reveal body worn cameras allow their officers to better prevent and detect crimes and offences.


The front facing screen is being used to alter subject’s behaviour during confrontational incidents. This calming affect has been replicated throughout the 30 countries that Reveal body cameras operate in.

During the first field trial, the department used the RS3-SX body cameras to record incidents that involved complaints or abusive behaviour by the public. These recordings were then used by supervisors to review incidents and complaints to train frontline officers in handling emotional or abusive persons.

The trial covered emergency units in New Territories North, West Kowloon and the Hong Kong Island.

Police officers will also handle confrontational scenarios more efficiently since actions are documented, a Hong Kong Police spokesperson said.

The field trial, now in its second round, has extended the use of cameras to all emergency and tactical units across the city, including dispatch units on patrol duty.

The Police ensures that it complies with Hong Kong’s personal data protection laws to mitigate privacy issues around video footage. “Footage that does not carry any investigative or evidential value, or constitute any other legitimate purpose will be deleted after 31 days from the date it was produced,” the department added. This is done through automated processes in DEMS, the Reveal Management Software.

“Any other request to access the video shall be processed under the PDPO [Personal Data Privacy Ordinance],” HKPF said.

The department will conduct a “thorough and comprehensive evaluation” of body-worn cameras once the trial ends in June 2015, a spokesperson said.

Interest in neighbouring regions has been sparked by the successful use of the technology by the HKPF. More recently the Singapore Police were also looking to trial body cameras on their front line officers.
