Hanging device for establishing an electrically conductive contact with a hanging article and a monitoring system utilizing same

摘要

The security system as presented is used preferredly to monitor paintings and other work of art. Essential component of the security system are suspending elements, for mounting e.g. paintings. The suspending elements also serve to transmit signals (data) or electrical power, for illumination purposes. It is preferred to implement a two wire bus system with the suspending elements. In case an alarm is triggered, the system according to the invention is able to immediately identify and display the time and the place of the objects to be guarded. Several levels of monitoring capabilities are provided, which work in cooperation with hardware consisting of different sensors or transponders. The security system in accordance with one embodiment is connectable to a network.
