Systems and methods for secure provisioning of detector units

A method for securely provisioning a detector unit, the method comprising:

• detecting, via a short-range communication interface, a coupling between a mobile computing device terminal and a detector unit, the mobile computing device terminal being attachable to the detector unit via a mechanical adapter coupled to the detector unit such that a top surface of the detector unit is adjacent to a bottom surface of the mechanical adapter and a top surface of the mechanical adapter is adjacent to a bottom surface of the mobile computing device terminal;
• responsive to the coupling, obtaining, via one or more processors, identification information uniquely identifying the detector unit;
• transmitting, via a wireless communication network, the identification information to an access server;
• receiving, via the wireless communication network and from the access server, an access response indicating that the detector unit is an authorized device;
• and
• responsive to receiving the access response, provisioning, via the short-range communication interface, the detector unit with configuration information that enables the detector unit to access the wireless communication network.
