The Sabra Fence 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 Sabra Fence System utilizes a x86 based computer running optimized Windows XP or Windows 7 with a color 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 Sabra Fence system uses a modular approach to perimeter security; encapsulated along a combined power and communications cable are the Sabra Fence 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 Sabra Fence 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 Pre-fabricated Aluminum foam paneling, onto the adjacent Chain wire 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 color 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 Sabra Fence 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 no specific events.
The calculations and process algorithms used in 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.
Sabra System sensors are:
- A temperature sensor which detect unusual changes in temperature.
- A magnetic sensor for use with the 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 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
Installation of Sabra Fence is a relatively fast and simple process for most applications.
The Sabra Fence 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.
