1. A sensor device for sensing a predetermined activity within an area under surveillance and operative in a system including a plurality of sensor devices and a surveillance system coupled to said plurality of sensor devices, comprising:
- one or more sensor devices of a first predetermined type and operative for sensing a predetermined activity and to output raw sensor data corresponding to the predetermined activity;
a means for processing raw sensor data coupled to one or more sensor devices and responsive to receive raw sensor data from each of the one or more sensor devices, associate a predetermined sensor type identifier with the raw sensor data, and associate a sensor identifier with the raw sensor data and the sensor type identifier; and
an output port operative to provide data that includes the raw sensor data, the sensor type identifier and the sensor identifier for utilization by the surveillance system.
