An identification message is sent from a sensor apparatus, over a wireless communication network, in response to a trigger event sensed by a sensor device in the sensor apparatus. The identification message includes a unique identifier of the sensor apparatus. The identification message is received at a network server. A pre-configured action profile associated with the unique identifier in the received identification message is accessed by the network server. A response action is caused to be executed based on information in the accessed action profile. The sensor apparatus is paired to a subscriber account before first use, thereby allowing secure initialization.
