Australian Security Fencing - Sabra Fence

Australian Security Fencing - Sabra System is a new and innovative Perimeter Protection System combining cutting edge electronics and complex mathematical algorithms to create a highly sensitive and sophisticated detection medium with environment canceling controls.

The Australian Security Fencing Sabra Sensors identify intrusion attempts by sensing movement in the supporting structure using MEMS (Micro Electrical Mechanical System) technology. The digitized response is then analyzed by complex mathematical algorithms to detect between true attacks, random false alarms or environmental events.  Detection is down to the individual sensor. Standard spacing is at 5metres, (3metres option available). The Australian Security Fencing Sabra System utilizes  a x86 based computer running optimized Windows XP or Windows 7 with a colour graphical display showing the current state and alarms of each sensor overlaid onto customized client oriented maps/images given intuitive understanding of the exact location of detected events. Via an external interface, PTZ cameras or lighting can be activated to give real time visual confirmation.

The Australian Security Fencing SabraFence System uses a modular approach to perimeter security; encapsulated along a combined power and communications cable are the ASF SabraFence sensors. Within each sensor is a Power Conditioning circuit, Microprocessor, Sensing Elements and Communications Bus requirements. Each sensor is individually addressed to allow unique interaction for event detection, parameter setting, and sensitivity calibration. This will allow a single ASF Sabra Sensor chain to span multiple substrate materials within the same chain length. For example, a chain may be run out of an office building constructed of Prefabricated Aluminum foam paneling, onto the adjacent Chainwire Security Fencing, across/under a gate, onto a concrete block/brick wall. It may then continue on via a high security weld mesh, or palisade inner high security area, including the colour bond weather proofing, before  finishing up on the inside of a solid concrete vault. Each sensor of this theoretical perimeter is as sensitive as the next due the unique calibration that each will receive.

The Australian Security Fencing SabraFence algorithm has a multilevel approach to the detection and calculation of collected data in determining events. This complex and random sequence analysis of the gather individual and collective data successfully eliminates environmental and non specific events. The calculations and process algorithms used in ASF SabraFence are highly complex and use detailed statistical mathematics to determine unique events, that may be of lower amplitude signal, hidden in a noisy fence line, i.e.  A ladder being placed on the fence on a windy day.

Also on the ASF Sabra System sensors are:

• A temperature sensor which detect unusual changes in temperature.
• A magnetic sensor for use with the ASF Sabra Fence Magnet at gates and crossing points.
• Smart patrol recording – identifies guard rounds passing each sensor through selection and recording on the control unit.

The ASF Sabra Fence Hub unit software performs several operations in parallel:

• Scanning the Sensors in the chain, receiving a report about the condition of all the Sensors
• Reporting events to various external units such as alarm systems, dry contacts or communications components
• Displays the status of the Sensors on the local user interface, typically used by technicians during installation
• Simultaneous recording of events on demand

Under development currently and expected to be released late 2011, The ASF SabraFence Wide Area System, connects multiple ASF SabraFence Hubs, creating seamless, single network of detection that may cover many hundreds even thousands of sensors distributed along kilometers of perimeter lines, or security sensitive infrastructure.

Installation of ASF SabraFence is a relatively fast and simple process for most applications. The ASF SabraFence Sensor is specially shaped to allow mechanical fastening via a bolt and nut, or a screw or similar. Alternatively the Sensor can be affixed via ties to the structure.
