Claim:
1. A security system for an environment-controlled transport unit including a transportation refrigeration unit, the security system comprising: a fuel sensor mounted to the environment-controlled transport unit, wherein the sensor is configured to monitor a fuel supply level to the transportation refrigeration unit; and a communication device embedded in the transportation refrigeration unit of the environment-controlled transport unit, the communication device being configured to receive fuel supply level data from the fuel sensor, and to send the received fuel supply level data to a controller being remote from the environment-controlled transport unit, wherein the controller is configured to monitor the security status of the environment-controlled transport unit and to determine a security risk at the environment-controlled transport unit based on the received fuel supply level data, wherein the security risk at the environment-controlled transport unit includes a fuel theft of the environment-controlled transport unit, and wherein the controller determines the fuel theft of the environment-controlled transport unit based on a current location of the environment-controlled transport unit and the received fuel supply level data.
