OpsTagTM solutions provide prison authorities with reliable tools for managing the inmate population.


The OpsTag RFID uses Radio Frequency Identification (RFID). OpsTag RFID utilises radio wave technology to identify individuals detained within the prison. It allows information to be collected quickly and automatically and does not require contact or line of sight.

The reader generates an electromagnetic field through its antenna. Once the tag enters the detection area, it becomes active when receiving a signal through its own antenna. This signal is used to turn on the tags transmitter and allows the tag to communicate and exchange information with the reader. The reader then transmits the data to a computer or server for processing and management.


With this system, inmates wear a wrist bracelet which issues a signal every 2 seconds and is caught by RFID readers deployed throughout the facility. The bracelets that are assigned to the prisoners are personally customised with schedules and zone limitations for effective supervision. Officers and staff also carry an RFID device attached to their belts. A central server keeps track of the position of all inmates, officers and staff in real time.

The system communicates with the monitoring centre to report locations or violations of the monitored offenders based on their assigned schedules, around the clock. Extended memory capacity enables the unit to process and store a large amount of data prior to uploading it to the monitoring centre or control room. The information received can be stamped with the time of data arrival as required. Operators define and control a preferred reporting mode.

The tags are water resistant and tamper proof. If an inmate tampers with the device, an alarm will be raised. As with all alarms raised, the identity and position of the inmate will be displayed in the control room on monitors and essential information derived from inmate tags can be simultaneously distributed to staff pagers, central monitoring stations and or designated remote locations within the gaol.


The RFID prison management system is intended to have a three-fold function. It ensures inmates do not escape by issuing an alarm if the bracelet approaches the gaol perimeter; it reduces violence by allowing officers to monitor who is congregating with whom; and it allows for administrative functions such as tracking where an inmate is when they are needed.

The system also reduces costs by eliminating headcounts throughout the day. By using the RFID system, the inmate population can be counted every few seconds and an alarm can be created if anyone is missing.


The OpsTag RFID device for staff has a red button that the staff can press in an emergency. If that button is pressed, an alarm in the control room will alert staff and help can be deployed immediately.

The OpsTag system can measure distance between 2 prisoners and contact rules can be designed so that for instance, two prisoners that are not to have contact can be managed through the system to avoid and control their contact.



The use of OpsTag RFID device means that inmates can be monitored within
the areas where readers are set up. Once the OpsTag RFID installation is completed, there are no ongoing costs in relation to monitoring of the system.

Prisoner Management

Flexible monitoring resolutions are available to accommodate any gaol facility requirement, with automated system checks for operational stability providing reliable inmate supervision.

OpsTag RFID’s can be installed in various locations be they indoor or outdoor settings of varying shapes and sizes. The system bypasses physical barriers and obstacles, creating virtual boundaries within facilities.

Where inmates and staff need to be taken out of the prison, and therefore outside the coverage of the OpsTag RFID readers, we suggest implementation of portable Opsec Mesh Wireless solutions to compensate.



OpsTag GSM is for those inmates and accompanying staff who are required to be outside the prison on an ad-hoc basis. The OpsTag GSM device is also recommended for parolee tracking.

It is an all in one real-time tracking device. Designed to be worn on an inmate/parolee’s ankle, this device uses Global Positioning (GPS) and the mobile telephone network (GSM) to monitor and report position to a custom designed monitoring system.

OpsTag GPS/GSM has been designed to meet the need for an active tracking device capable of reporting immediate alarms to a monitoring centre if the offender leaves a defined inclusion zone or enters a defined exclusion zone.



OpsTag GPS/GSM is about the same size as a small PC mouse, is comfortable to wear and weighs in at just over 150g. It has a fully re- chargeable battery, is completely waterproof to 5 metres, and has a tamper resistant strap, a panic alarm, personal alarm notification and on-board management controls.

Through intelligent battery management software, the battery lasts up to 30 hours when used in full active tracking mode. Using the specially designed charging base, it can usually be re-charged in just 30 minutes while still being worn.

Incorporating layered location technology like GPS and worldwide GSM communications means that it can compensate for poor performance of any single location technology. Where GPS is poor, such as inside buildings, the device resorts to GSM positioning.

The monitoring system uses the GSM network for remotely programming new control parameters into OpsTag GSM such as inclusion or exclusion zones. It uses the same network for sending location data and alarms to the monitoring system. OpsTag GSM can be set to 3 different modes:
