Shock sensors or vibration sensors detect vibration
Those with a processor will analyse the vibration amplitude and duration and determine if it is a real "shock"
Those without processors give contacts but they will switch on and off very rapidly, and are prone to false alarms, eg a slight tap may cause it to trigger
For comfort to process these select the Vribraton zone type which has sensitivity = 20 ms so it can detect the transitions, but use a Zone Response Vibration Analyser in Default Responses. This makes an alarm if there are 3 activations within 30 seconss
