Abstract: There is provided, a computer-implemented method of monitoring overall latency, comprising: monitoring a sequence of images of an actuator controlled by a user interface presented on a display of a client terminal, detecting, in a first image of the sequence of images, a first visual indication denoting termination of a user triggered activation of movement of the actuator via the user interface, detecting, in a second image of the sequence of images, a second visual indication denoting termination of the movement of the actuator in response to the termination of the user triggered activation, computing an overall latency from a timestamp associated with the second image and a timestamp associated with the first image, and when the overall latency is above a threshold, adjusting at least one system parameter of a system connecting the client terminal with the actuator and with a camera that captures the sequence of images.
