12. A method for collecting and processing surveillance data within a sensor unit, the method comprising the steps of:
receiving raw sensor data from a sensor device, wherein the raw sensor data represents data gathered from a monitored area under surveillance;
analyzing the raw sensor in order to determine if the sensor data indicates that an activity has occurred in the area under surveillance;
generating an event record that includes data regarding the activity if a determination has been made that an activity has occurred, wherein the event record comprises data relating to the location of the activity within the area under surveillance;
transmitting the event record to a data unit; and
transmitting control commands to the sensor device.
13. The method of claim 12 , further comprising the step of classifying detected objects that are identified as being detected within the area under surveillance.
14. The method of claim 13 , wherein the step of generating an event record further comprises the step of utilizing data regarding the classified detected objects if a determination has been made that an activity has occurred.
15. The method of claim 14 , wherein the step of analyzing the raw sensor data to determine if an activity has occurred comprises the step of determining if there has been any motion detected within an area under surveillance.
16. The method of claim 15 , wherein the step of classifying detected objects further comprises the step of classifying the detected objects based upon known object types.
17. The method of claim 15 , wherein the step of transmitting control commands to the sensor device comprises configuring a sensor unit controller to receive and transmit control signals from an exterior control unit to the sensor device.
18. A computer program product that includes a computer readable medium useable by a processor, the medium having stored thereon a sequence of instructions, when executed by a processor, causes the processor to execute the steps of:
receiving raw sensor data from a sensor device, wherein the raw sensor data represents data gathered from a monitored area under surveillance;
analyzing the raw sensor in order to determine if the sensor data indicates that an activity has occurred in the area under surveillance;
classifying detected objects based upon known object-types objects that are identified as being detected within the area under surveillance;
generating an event record that includes data regarding the activity and the classified detected object if a determination has been made that an activity has occurred, wherein the event record comprises data relating to the location of the detected activity within the area under surveillance;
transmitting the event record to a data unit; and
transmitting control commands to the sensor device.
19. The computer program product of claim 18 , wherein the step of analyzing the raw sensor data to determine if an activity has occurred comprises the step of determining if there has been any motion detected within an area under surveillance.
20. The computer program product of claim 19 , wherein the step of classifying detected objects further comprises the step of classifying the detected objects based upon known object types.
