Surveillance systems and methods having both a radio frequency component and a video image are provided. The radio frequency component can determine the orientation and position of an RFID tag within a surveillance area. The orientation of the RFID tag is can be determined with respect to two or more orthogonal planes using inductance and a predetermined number of mutually orthogonal antenna loops.

A system for providing asset management and tracking capabilities of a tractor-trailer system includes a trailer device coupled to a trailer. A tractor device is coupled to a tractor and configured to communicate with the trailer device using a first communication protocol. A hand held device is configured to communicate with the trailer device using a second communication protocol and with the tractor device using a third communication protocol. A remote monitoring center is configured to communicate with the trailer device, the tractor device, the hand held device, using a fourth communication protocol; wherein the remote monitoring center is configured to monitor the tractor-trailer system based on association between the trailer device, the tractor device, and the hand held device.
