In the case of energy:
Active system
This means that you have a good source that emits radio waves or ultra-sonic rays into a room and record the reflection ray is when they travel back, now if someone comes in the range of this ray reflection and change their patterns can be used to trigger an alarm.
Passive system
This system uses detectors / sensors to sense rapid changes in infrared energy in the room. What this means, that when people enter the field of Señor have increased rapidly in the heat sensed by the infrared sensor; this in turn will send a message to the controller, which in turn sounds the alarm combination is determined by the user.
