Perimeter security system

Grealtec has develop the first System of optical detection of intrusion into flexible and semirigid fences using the technology of Plastic Optical Fiber, eliminating 100% false alarms caused by wind and vibrations. It is also responsible for the centralization of alarms from all areas (100 meters of fence by area) on a single Master equipment, which communicates the alarm via SMS messages up to 5 users or monitoring through an integration software.

OPERATION

The equipment sensor has a transmitter and an optical receiver POF (Plastic Optical Fiber) which connects a loop that has been previously made pass through the fence. The flexion, by intrusion, of the fence causes a decrease in the luminous flux that is analyze by the equipment, which gives us a 100% real alarm.

The other devices of the system are responsible for multiplexing the signals from all the Slave equipment of the perimeter. To achieve this, a POF-BUS cable is used, which integrates a fiber that communicates the data along with the power cord for all the Slave equipment of the perimeter. 
The Master equipment analyze each of the zones and in the event of an alarm, it sends a SMS message of alarm in the area where there is someone trying to access, being able to monitor them by a integration software or a module of relay outputs.

ADVANTAGES COMPARED TO OTHER SYSTEMS

• - Simplicity: connection of the fiber iup to 20 mm allows quick and easy installation.
• - Resistance and robustness: it does not oxidize, resist extreme weather conditions and goes not age.
• - Reliability: without false alarms caused by atmospheric interferences or any type of movement of animals.
• - Adaptability: we adapt to any type of installation, new or existing.
• - Safety: optical signals cannot be bypassed.
• - Immediate response: immediate dispatch of the alarm signal to any computer or cell phone. In areas without coverage, satellite communication can be installed.
• - Versatility: the same system provides the ability to monitor up to 4 different variables (e.g.: energy generated, battery level, water level, etc.) and acts on two systems remotely.
