Hong Kong prisons to test new CCTV system that can detect suspicious behaviour by inmates
- Computer video analysis will help spot erratic or aggressive motions and send alert to staff
- New tool part of ‘smart prison’ push to modernise city’s correctional facilities
Hong Kong prisons are set to test a new system within the next two months that can detect suspicious behaviour by inmates.
Revealing more details in the Legislative Council on Friday morning, security minister John Lee Ka-chiu said prisons would install a new CCTV system with a video analytics function that could detect erratic and aggressive motions by prisoners, looking out for fights and suicide attempts.
When suspicious movement was detected, the system would send an alert to prison staff.
“If there is a fight in the canteen, the motion would be different from the quiet state, like in usual circumstances,” Lee said.
“Experts gathered lots of data and input it into the system so that the computer can analyse [the captured motion]. The authorities can draw manpower instantly and intervene in a fight if notified about abnormal behaviour.”
