Abstract
A system for surveillance of a mobile or movable object is placed in a surveillance enclosure. The system includes and it comprises a transmitter/receiver circuit for first and second object-monitoring signals (sco1, sco2). The first and second signals monitor the presence of the object and the position of the object respectively. A transmission circuit is provided for transmitting an alarm-triggering signal. The transmission circuit receives the first and second object-monitoring signals and enables an alarm-triggering signal (sda) to be transmitted conditionally on the basis of a logical and/or analog combination of the first and second object-monitoring signals. The invention is applicable to surveillance of valuables or of works of art.
