Abstract

A security monitoring system with addressable capability is provided. This system allows a plurality of video cameras to be connected to the security guard room via a single cable instead of a plurality of dedicated cables, as in the prior art. The security monitoring system comprises the following: a cable; a central control unit connected at the first end of the cable, capable of issuing a first signal; at least one addressable video camera connected at the second end of the cable connected to the central control unit; and a monitoring device for displaying a second signal. The addressable video camera receives the first signal from the central control unit and compares the first signal with a preset value; if these match, the addressable video camera sends out a second signal via the cable back to the central control unit. This second signal is then displayed on the monitoring device coupled to the monitor. The signal transmission between the central control unit and the plurality of video cameras can be carried out over one single cable. The arrangement and handling of the security monitoring system is therefore considerably simplified.
