Fence Protections


Catalog SIOUX

Sioux is an innovative fence mounted perimeter intrusion detection system, the result of a research project conducted in collaboration with the Milan Polytechnic, which has resulted in the joint filing of 3 patents.
The system comprises a multitude of mems type tri-axial accelerometer sensors, organised in sub-systems of 7. The sub-systems are made up by 1 master sensor and 6 slave sensors: each is individual and provides its own signal on a different channel to its master sensor.
each master sensor contains the physical location of the 6 slave sensors that it analyses and is therefore able to combine this analysis of signal distribution in relation to the adjacent sub-systems



Thanks to the ability to process every sensor that makes up the system, it is possible to adapt the response to any type of fence, even with mixed types within the same site. it is possible to adjust the working parameters for each zone, and, inside the zone, for each individual sensor.
the very high probability of detection (pod) and the very low nuisance alarm rate (nar) of this system, are the result of processing, for each of the three accelerometer signals produced by each transducer, according to “fuzzy log.

the installer can easily configure the zones in the field by walking around the perimeter and physically “touching” the sensors to select the beginning and end of each of the available zones. this capability makes it a much more immediate, quick and easy operation, while it is still possible to
configure remotely using the sioux test software.

by exploiting the capabilities of the mems sensors with respect to the acceleration of gravity it is possible to gain information about the position of the accelerometer in free space. during installation the position of the mems accelerometer, whatever it is, will be memorised. if the position alters by more than a pre-set, variable number of degrees (e.g. 5°) it will produce a tamper alarm.this allows sioux to detect possible physical changes in the fence, which probably indicate an attempt to breach or re-position the fence protection system, either when the sensor is removed from the surface of the fence, or when the fence is bent while trying
to break through.

each mems is identified and analysed individually via a specific channel on its master sensor, which knows the exact location of the sensor. each intrusion event will be identified by point with a precision of 1m regardless
of the distance between the sensors.

Full Products Range:

SIOUX MEMS: innovative system developed by CIAS in collaboration with Milan Politecnico University and based on MEMS technology; thanks to a small chip –the same we can find on any smartphone- all accelerations provoked by any climbing, cut, or sensor displacement attempts, as well as fence lifting and leaning of a ladder against it and so on, are translated into alarm signal. Every and each sensor can be individually set, thus suiting for application both on rigid and on mesh fences, with no need of previously separating different segments of fence before installation.
• Innovative accelerometer MEMS sensor, auto-addressing
• 700mt coverage and zones from 35mt
• Precision of detection of 1 meter via IP – through SDK
• Easy installation by placing sensors every 5m regardless their positioning on panels
• Covering up to 6m in height with only one line of sensors
• Inclinometer system for tamper detection
• 700m covering by each control unit: IP & PoE and with 20 relay output
• Operating temperature between -40/+70°C
• 10-years events memory
• 6-years warranty against manufacturing default

APACHE FIBER: system based on opto-phonic technology and interferometer measurement, that is to say it measures the difference in light emitted by a laser and in the signal received back. Vibrations, received by the optic fibers installed on a fence, redirect the light reflected inside the fiber so that it returns different than it was originally transmitted. Such a signal of light is transformed into an electrical signal , which the DSP on-board will analyze, filter and provide to an alarm relay for signaling any attempt of climbing and cut of the fiber itself or of the fence.
• System providing single or double zone up to 2000m
• Zones from 500mt
• Suitable for any kind of fence: both rigid and weld-mesh
• Possibility of configuration in loop or daisy-chain
• Easy to install, with UV-resistant ties
• Possibility of set up via software or through on-board rotary switches
• Connectable to any kind of anti-intrusion control panel
• Operating temperature between -40/+70°C
• 3-years warranty for the analyzer and 10-years on the fiber cable

BLACKFEET CABLE system based on magneto-phonic technology, that is to say a cable with 2 magnetized plastic sheats hosting inside 2 wires free to move; vibrations detected by the cable installed on the fence are translated into an electric signal; which is duly filtered and digitalized by the board in the control unit, and which provides one relay of alarm for climbing and cut attempts of the cable itself or of the fence.
• System in kits of 50/100/150/200/300m
• Zones from 300m
• Suitable for any kind of fence: both rigid and weld-mesh
• Suitable for wall application anti-breakthrough
• Easy to install, with UV-resistant ties
• Easy to adjust through switches – no software
• Connectable to any kind of anti-intrusion control panel
• Operating temperature between -40/+70°C
• 15-years warranty on the sensor cable
• Accessories compatible to other systems based on the same technology

We remind that for all fence systems data collection can be made through IB SYSTEM IP (or traditional RACK).
All solutions can be integrated to Cias Supervisor system with graphic maps also via IP and RS485, or to any third party’s system via SDK. (NB. Blackfeet only via I/O input).
Cias perimeter systems “talk” to each other to satisfy different levels of site protection and to provide one unique point of reference for any needs of outdoor security protection.
