A multi-application-transceiver device (100), control computer, computer implemented method and computer program product for operating the multi-application-transceiver device is disclosed. At least one signal transceiver (110) receives a reflected signal (S2) in response to an original signal (S1) sent by the at least one signal transceiver (110). The reflected signal (S2) is reflected from at least one target object (1). A signal conversion unit (150) converts the reflected signal (S2) into digital format. A digital signal processor component (120) pre-processes the converted reflected signal using an alterable rule engine (121) with a received rule set to discriminate a state in change of the at least one target object (1) against an earlier state of the at least one target object (1) in the context of a particular monitoring application. A middleware component (130) communicates with at least one remote computing device (300) wherein communicate includes to send the pre-processed signal to the remote computing device (300), and to receive from the at least one remote computing device (300) the rule set for the alterable rule engine (121). The received rule set defines an application specific setting for the at least one signal transceiver (110) and for the digital signal processor component (120) to enable the particular monitoring application.
