1. An Electronic Monitoring system is a method that permits full-time monitoring of an offender who is wearing a GPS equipped EM bracelet in order to ensure that the offender does not enter zones that he is excluded from, or that he remains in zones, per the release conditions that have been imposed on him.

2. The Electronic Monitoring (EM) device is a bracelet worn on the offender’s ankle to monitor the offender’s geographical location. The EM device uses 3 different localization methods: GPS mode, cellular mode, and RF unit mode. The primary localization method is the GPS mode that receives position signals from satellites orbiting the earth to permit monitoring of the offender’s geographical location. In the event that the EM device doesn’t have connections with GPS satellites the EM device must fall back (or revert) to cellular mode for localization. Finally, when the EM device is within a predetermined proximity of an RF unit, the EM device relies on the RF mode of localization monitoring compliance to an inclusion zone.

3. RF unit: When the EM device is within a predetermined range of the RF unit, the RF mode then takes over as the primary location monitoring method. The intent is to use the RF mode to confirm the offender's presence in an inclusion zone (e.g. home). The RF unit can be remotely configured for different range settings and for immediate reporting to the EM Data centre when the bracelet unit goes out of range of the RF unit or if the RF unit is moved.

4. The EM Data Centre is the main component of offender monitoring with a central database being linked wirelessly to the offender’s EM device and RF unit. The Electronic Monitoring Data Centre houses the server which holds the software that gathers the data that captures and logs the offender’s movement, with capability to alert when the offender enters an exclusion zone or fails to remain within a defined inclusion zone. The server has web browsing capability to enable remote accessibility of offender’s monitoring data by CSC authorised personnel.

5. The CSC National Monitoring Centre (NMC) is where the authorised CSC personnel monitor offender movement by accessing the data available from the EM Data Centre.

1. Technical Acceptability

   1. CSC must ensure the system is fully operational and the contractor must be able to provide all test data that demonstrate all system technical specifications are met. The contractor will be required to arrange for a demonstration as defined by CSC. CSC may rely on manufacturer's test results for specific areas of the specification where an independent test facility has conducted the test and the facility is deemed acceptable to CSC.
