More Information
Summary:An electronic monitoring device for monitoring an individual and detecting signal blocking. The electronic monitoring device may be equipped with GPS and/or RF communication technology that may be interrupted intentionally or unintentionally. The device compares sampled incident energy with a reference level to identify an occurrence of blocking the transmitter signal. The device may also base determination of a signal blocking occurrence on input from a status detection module. Status information is also leveraged to intelligently calibrate the device to more robustly determine a tampering event.
