Introduction

The Correctional Service of Canada has installed Perimeter Intrusion Detection Systems (PIDS) in its maximum and medium security institutions across the country. PIDS is designed to improve peri-meter security and is highly cost-effective, since the system, together with two motorized patrols, minimizes the need to staff guard towers.

PIDS is made up of five complementary electronic systems:

• Fence Disturbance System (FDS)

• Motion Detection System (MDS)

• Closed Circuit Television (CCTV)

• Perimeter Public Address System (P PAS)

• PIDS Integration Unit (PIU)

The integrated PIDS detects any physical contact with the perimeter fence or any movement between fences, and activates an alarm in the Main Communications and Control Post (MCCP), which the MCCP operator immediately acknowledges. Then, using closed circuit television (CCTV), the operator verifies whether the perimeter of the institution is, in fact, being breached and sends response staff to the scene as required. Two motorized patrols operating around the perimeter provide visual confirmation and respond promptly to any alarm.

Fence Disturbance System An Overview of PIDS

The inner fence line is divided into sectors or zones, each equipped with independent sensors and related electronic support equipment. Any vibration — caused by climbing, cutting or disturbing the fence in any way — produces an electronic impulse that triggers an alarm in the Main Communications and Control Post inside the institution.

A public address system allows the officer in the MCCP to speak to an escapee in the area where the alarm sounded.

The area between the inner and outer fences is also equipped with sensors to detect movement. And, again, an alarm in the Main Communications and Con-trol Post alerts the operator.

At walled institutions, the outside wall is equipped with a disturbance system for detecting attempted escapes. There are motorized patrols that respond to alarms 24 hours a day.

The areas between the fences and inside the inner fence are kept under surveil-lance by means of a full system of cameras around the perimeter. The video output from the cameras can be sequentially fed to the television monitors in the Main Communications and Control Post.

When an alarm is generated by the Fence Disturbance or Motion Detection subsys- tems, the cameras surveying the sector in question are automatically switched to the monitors in the Main Com-munications and Control Post. At the same time, video cassette recorders automatically record activity in the area where the alarm originated.

Closed Circuit Television Motion Detection System

PIDS Integration Unit

The PIDS Integration Unit collects and sorts all data received from the Perimeter Intrusion Detection System and presents this informa-tion to the operator via a Video Display Unit housed in the Main Communications and Control Post. The unit

has been designed — using recognized human engineer-ing principles — to reduce the amount of extraneous information presented to the operator. As a result, decision-making in an emergency is more efficient.

Supplementary Intrusion Detection System

SIDS is a closed circuit television system that complements the main CCTV system associated with the perimeter fence line. It is used to monitor inmate activities in the exercise yard and to scan the outer perimeter and roof tops of the institution. A separate monitor is located in the Main Communica- tions and Control Post under an operator's constant surveillance.

Motorized Patrols Reliability

The Perimeter Intrusion Detection System operates efficiently under the most extreme weather conditions (snow, sleet and rain, for example). PIDS is equipped with an uninterruptable power supply in case of power failure and with anti-tamper alarms to prevent interference. A well-coordinated maintenance program ensures that repairs can be made rapidly, any time of the day or night.

Radio-equipped patrol vehicles, driven by armed correctional officers, are deployed around the outside perimeter — 24 hours a day, 365 days a year — to assess and verify visually any alarms, and to respond as needed.

Training

PIDS is currently used in the following 23 institutions:

• Atlantic and Dorchester in New Brunswick; Springhill in Nova Scotia.

• Regional Reception Centre, and Archambault in Ste-Anne-des-Plaines; Donnacona, Port-Cartier, Drummond, Cowansville and Leclerc in Quebec.

• Millhaven, Collins Bay, Joyceville and Warkworth in Ontario.

• Stony Mountain in Manitoba; Regional Psychiatric Centre and Saskatchewan Penitentiary in Saskatchewan; Edmonton and Drumheller in Alberta.

• Kent, Matsqui, Regional Psychiatric Centre and Mission in British Colombia.

As the PID Systems have been installed, correctional staff have been fully trained to operate the Main Communications and Control Post. Operators also receive "refresher" training each year. Working in close communication with the mobile perimeter patrols, they provide a timely and effective security response to any alarm.

Cost Effectiveness

The cost of maintaining a PID System varies with the institution using it.

Under normal circum-stances, the system makes it unnecessary to staff guard towers, although these remain for use as observa-tion posts while offenders participate in outdoor activities.

Mobile Intrusion Monitoring System Other Electronic Detection Systems

At some medium security institutions, where the type of offender does not require the same level of security, a single electronic detection system is used. Installed on the perimeter fence line, this system is similar to that used at major sites.

When the perimeter is violated, an alarm sounds on a panel located in a mobile patrol vehicle. The patrol officer immediately acknowledges the alarm and responds promptly to any attempted escape. A back-up alarm system is located at the main entrance to the institution. Staff assigned both to patrol vehicles and to the main entrance are fully trained and a well-coordinated maintenance program ensures optimum performance. Like the PID System, the Mobile Intrusion Monitoring System allows correctional officers to be redeployed while still ensuring better protection for the public.

At present, Bowden institu-tion in Alberta is equipped with this system.

Owing to unique geographi-cal and environmental features at several of our correctional facilities, some security requirements are highly site-specific. In these instances, the Correctional Service of Canada has iden-tified other means for detect-ing and preventing escapes. One of these is the use of night vision camera equip-ment, which greatly enhan-ces the security surveillance on the outer perimeter of an institution.

Camera monitors are located in the towers and at the main entrance, enabling officers to assess and verify any unauthorized movement on the perimeter. This visual assessment system enhan-ces the overall security

of the outer institutional reserve, making it easier for correctional officers to perform their duties.

William Head institution — located on a large peninsula of Vancouver Island and often fog bound — is equipped with night vision cameras.

Conclusion

From its first operational installation, PIDS has proven its ability to perform well. Any attempted breach of the outside perimeter of a PIDS installation is readily detected. With staff who have been extensively trained, this highly efficient security technology offers reliable protection for the surrounding community and a more effective use of staff resources.
