Abstract
A fiber-optic surveillance system () includes a fiber-optic sensor () comprising a serial array () of fiber-optic point-sensors (), successive point-sensors being linked by a distributed fiber-optic sensor (). The system allows the location of intruder events along the sensor to be determined, and provides a reduction in the incidence of false-alarms compared to prior art systems.
