1. A system comprising: a first fixed video detector and a second fixed video detector; and a controller configured to receive patient data from a mobile biomedical sensor associated with a patient, the controller is further configured to receive visual data from the first fixed video detector and the second fixed video detector, the controller is further configured to perform surveillance of the patient based on a combination of the visual data and the patient data; wherein the controller comprises a movement module configured to conduct real-time analysis of the patient in a first observation range of the first fixed video detector and configured to extrapolate a predicted future location of the patient in order to determine a second observation range into which the patient is likely to roam in the future, wherein the second fixed video detector is activated in response to the extrapolation of the predicted future location of the patient in the second observation range.
