A method, performed by a computer device, the method comprising: receiving a video stream from a camera; displaying the video stream on a display; obtaining, via an eye tracking sensor, gaze information for an operator watching the display; generating a historical gaze heat map for the video stream for a time period based on the obtained gaze information, wherein generating the historical gaze heat map includes generating a value for a particular location in the video stream indicating how frequently an operator's gaze point fell on the particular location during the time period, wherein the time period is longer than a day, and additional information identifying a particular time of day or a particular day of week when the gaze information was collected; determining, using the generated historical gaze heat map, that a location in the video stream satisfies a requirement for a low interest area by determining that an operator looks at the location less than a threshold number of times per unit time or a threshold percentage of time out of a total time watching the video stream; designating a first location as a first low interest area for a first time of day or day of week based on a first subset of the historical gaze heat map generated for the first time of day or day of week over multiple instances of the first time of day or day of week; designating a second location as a second low interest area for a second time of day or day of week different from the first time of day or day of week, wherein the second low interest area is different from the first low interest area, based on a second subset of the historical gaze heat map generated for the second time of day or day of week over multiple instances of the second time of day or day of week; and instructing the camera to decrease a bit rate of the video stream in the first low interest area during the first time of day or day of week and in the second low interest area during the second time of day or day of week. receiving a video stream from a camera; displaying the video stream on a display; obtaining, via an eye tracking sensor, gaze information for an operator watching the display; generating a historical gaze heat map for the video stream for a time period based on the obtained gaze information, wherein generating the historical gaze heat map includes generating a value for a particular location in the video stream indicating how frequently an operator's gaze point fell on the particular location during the time period, wherein the time period is longer than a day, and additional information identifying a particular time of day or a particular day of week when the gaze information was collected; determining, using the generated historical gaze heat map, that a location in the video stream satisfies a requirement for a low interest area by determining that an operator looks at the location less than a threshold number of times per unit time or a threshold percentage of time out of a total time watching the video stream; designating a first location as a first low interest area for a first time of day or day of week based on a first subset of the historical gaze heat map generated for the first time of day or day of week over multiple instances of the first time of day or day of week; designating a second location as a second low interest area for a second time of day or day of week different from the first time of day or day of week, wherein the second low interest area is different from the first low interest area, based on a second subset of the historical gaze heat map generated for the second time of day or day of week over multiple instances of the second time of day or day of week; and instructing the camera to decrease a bit rate of the video stream in the first low interest area during the first time of day or day of week and in the second low interest area during the second time of day or day of week.
