Abstract: An anti-theft protection system for goods presented to the public includes a set of sensors connected to the goods and linked to a control unit capable of determining states, the states being at least a state of presence of the goods and a state of theft attempt and/or actual theft, the shift from a state of presence of the goods to a state of theft attempt and/or actual theft resulting, in the absence of inhibition of the detection for the sensor, in the control unit being set into alarm, the control unit including or being connected to a sonorous alarm generating elements.

Abstract: A telesurveillance system of objects whose presence is monitored remotely by a computerised control station over a computer network. At least one master central station has a unique identifier connected to the network, at least one detector having statuses in relation to the presence or not of an object, the control station being informed of the changes in status via the network, and the user may have a personal identification elements readable by a reader of the master central station, the letter including elements to wait, in a surveillance state, for the changes in status and reading the identification element, to switch to a state of alert to a change in status and to switch to a neutralised state during a determined neutralisation time by reading the personal identification element.

Abstract: An electronic wire-based safety device for the detection of a theft of an object to be protected, the device including at least one detector connected by a wire-based electric link to a signalling unit, the detector being arranged in relation with an object to be protected, the detector exhibiting at least a first electrical status in relation with the object and a second status when the object is detached from the detector, the unit including at least one threshold voltage comparator with inputs/outputs whereof one input is connected to the detector by the link and whereof at least one output indicates by signals at least the presence or the absence of the object in relation to the status of the detector.

Abstract: The invention concerns an electronic wire-based safety device for the detection of a theft of an object to be protected, the device comprising at least one detector (1) connected by a wire-based electric link (2) to a signalling unit (3), the detector being arranged in relation with an object to be protected, the detector exhibiting at least a first electrical status in relation with the object and a second status when the object is detached from the detector, the unit comprising at least one threshold voltage comparator with inputs/outputs whereof one input is connected to the detector by the link and whereof at least one output indicates by signals at least the presence or the absence of the object in relation to the status of the detector.
