A justice ministry spokesperson said Buddi will now conduct staff training and equipment testing.

B.C. Corrections expects to begin using the new devices in mid-December.

The hybrid radio frequency/GPS system has better tracking and reporting capabilities, including an ability to program in no-go zones and map an offender's travels. An alarm sounds at the central monitoring site if the offender enters a restricted area, and vibration alerts on the ankle bracelet remind the offender to comply.

According to Buddi, supervisors can use the data on offender movements to help them alter their behaviour to reduce the likelihood of reoffending. The real-time location data may also help police quickly rule out monitored offenders as suspects in a new crime.

The old ankle bracelet system, which relies on a telephone landline, could only verify that an offender was home and was mainly used to monitor house arrest and enforce curfews.

A to the province late last year said electronic monitoring technology is rapidly improving and future innovations are likely to include smartphone apps that alert victims when an offender is in the vicinity, as well as built-in drug and alcohol screening.
