Abstract: The invention relates to an apparatus for controlling radiofrequency sensing and audio sensing of a network. The network (100) comprises a plurality of network devices (111, 112, 113, 114), e.g. smart lights, and is adapted to perform radiofrequency sensing and audio sensing utilizing one or more of the network devices. A context parameter providing unit (121) provides context parameters, wherein the context parameters are indicative of a context in which the radiofrequency sensing and the audio sensing is performed. A controlling unit (122) controls the radiofrequency sensing and the audio sensing of the network in dependency of each other based on the context parameters. This allows for an improved monitoring of an area.

Abstract: A method is provided for monitoring optical cable for disturbance events by providing dual monitoring systems where optical signals are received from at least one optical fiber of the cable which are modified by disturbance events. Two separate and distinct algorithms are applied to the received optical signals to generate first and second outputs related to the disturbance event where in a control system information from the first and second outputs is used to determine if an alarm should be issued. The monitoring systems can use a single DAS system and operate on the same data independently preferably using one algorithm which uses ZONE processes to obtain data about different zones in the fiber. Alternatively two DAS systems can be used, one DAS system and one ZONE system or two ZONE systems. In all cases weather data can be used to assist the two algorithms in determining the presence of false alarms.

Abstract: A method is provided for detecting intrusion into an optical cable of a single mode optical fiber network comprising where monitoring light signals are transmitted along a telecommunications optical fiber to be monitored either along a fiber additional to a data fiber or by multiplexing onto a common fiber. The received monitoring light signals after transmission along the telecommunications optical fiber are analyzed for changes indicative of movement of the optical fiber for detecting an intrusion event. The monitoring light signals at the receive end of the fiber signals are monitored by feeding the signals from the single mode fiber into a multi-mode fiber in a manner which causes changes in modal power distribution which can be detected by taking a portion only of the modes.

Abstract: A disturbance, such as vibration from human activity, is located along a fiberoptic waveguide configuration (301-304) with two interferometers (801, 802) of the same or different types, such as Mach-Zehnder, Sagnac, and Michelson interferometers. Carrier signals from a source (101) are split at the interferometer inputs (201, 202) and re-combined at the outputs (701, 702) after propagating through the detection zone (401), where phase variations are induced by the disturbance (501). Phase responsive receivers (901, 902) detect phase relationships (1001, 1002) between the carrier signals over time. A processor (1101) combines the phase relationships into composite signals according to equations that differ for different interferometer configurations, with a time lag between or a ratio of the composite signals representing the location of the disturbance. The detected and composite values are unbounded, permitting phase displacement to exceed the carrier period and allowing disturbances of variable magnitudes to be located.

Abstract: A fiber optic mesh intrusion detection system includes a mesh structure made from twisted fiber optic cable to form a plurality of rhombic openings. For each of the crossings, a fastener is wrapped around the crossed fiber optic cable, serving both to provide the mesh structure and to protect the crossing points from tampering. Embodiments include fasteners having rotationally symmetric, interlocking portions such that when wrapped around the crossed cable the portions engage each other to hold the fastener in place.
