METHOD AND SYSTEM FOR MEASURING LATENCIES IN IP CAMERAS

摘要

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.

1. A method of determining one or more delays associated with an internet protocol (IP) camera, the method comprising:
issuing from a device, a control command to the IP camera; detecting, in a streaming video being received at the device from the IP camera, a change in one or more pixels in the video frames as a result of the control command being executed by the IP camera; and determining one or more delays associated with the IP camera by recording and comparing two or more of the following:
a command time being a time at which the control command was issued from the device;a capture time being a time at which the change in one or more pixels in the video frames as a result of the control command being executed by the IP camera was captured by the IP camera; and.a feedback time being a time at which the change in one or more pixels in the video frames as a result of the control command being executed by the IP camera was detected at the device.
