So i understand there are a number of different motion sensor technologies out where including Active Infrared (AIRs), Passive Infrared (PIRs), Microwave motion sensors and Ultrasonic motion sensors.
I would like to know what the advantages and disadvantages of these different types of motion sensors are and what (if any) vulnerabilities exist in them.
Additionally, have I overlooked any other similar motion sensing devices?
Edit: just to clarify, human based motion sensors is what im interested in. Practical non theoretical technologies. This question isn't to do with vibration sensors, glass break sensors etc
Edit: To limit the scope somewhat, lets stick to more common types of motion sensors rather than exotic situation specific types?
