Abstract: A method and system enable determining one or more delays associated with an internet protocol (IP) camera. The method includes issuing a control command from a device to the IP camera. A change is then detected in one or more pixels in video frames as a result of the control command being executed by the IP camera. One or more delays associated with the IP camera are then determined by recording and comparing two or more of the following: a command time; a feedback time; and a capture time.

Abstract: A communication system provides for automated detection, and resolution, of focus hunt. A server determines whether a predetermined number of blur metric transition (BMT) cycles, associated with a video stream, have occurred within a predetermined period of time or number of frames. In response to determining that the predetermined number of BMT cycles have occurred, the server determines that focus hunt has occurred. A BMT occurs when first and second blur metrics, determined for first and second video frames, transition from being greater than a blur metric threshold to being less than the threshold, or vice versa. In turn, a BMT cycle occurs when a BMT, of a first BMT and a second BMT, comprises a transition of blur metrics from less than the threshold to greater than the threshold and the other BMT comprises a transition of blur metrics from greater than the threshold to less than the threshold.

Abstract: A method is provided for automatically deleting user passwords. Upon receiving a password-less user authentication a password grace period timer is started. Upon expiration of the password grace period timer the password is deleted if a user confidence score associated with the user is greater than a confidence threshold.
