Please add some more content to your question. Are you asking to track manually or using any software / tools ? What are the things you have tried ?

You could use hybrid technology motion sensor is a combination of both active and passive sensors. It activates light or alarm only in such a case when motion is detected by both active and passive sensors.  Some examples :Passive Infrared Detectors (PIR),Mini Ultrasonic Motion Detector
