Abstract: Technologies are generally described for prevention of duplicate monitored areas in a surveillance environment. In some examples, a field of view (FOV) of a security personnel may be estimated. An image capture device with a coverage area that potentially includes the FOV of the security personnel may be identified and its FOV estimated as well. Next, an overlap amount between the estimated FOVs of the image capture device and security personnel may be determined. When the overlap amount exceeds a threshold, content provided by the image capture device may be assigned a low priority. The low priority content may be blocked from display, selected with lower priority among multiple available contents, or displayed with an indication of the low priority on a control center display. The FOV of the security personnel may be an actual view of a person or the FOV of a camera associated with the security personnel.
