Abstract

The present disclosure provides details of a system and method for a communication device for guards in controlled environments. The communication device is established based on an indoor wireless infrastructure in the controlled environment, receiving wireless positioning signals to calculate and determine the real-time location of a user carrying the device. The indoor wireless positioning can be combined with other available positioning methods to provide highly accurate positioning information of the guard. The communication device detects, monitors, and records activities of the guard during a period of time, and is controlled by the control center. The control center and the communication device respond quickly to different abnormal situations. In addition, the communication device detects contraband electronic devices and monitor surroundings of the guard. Thus, the disclosed system and method for the communication device provides improved communication and monitoring for guards in a controlled environment.
