Abstract
An electronic device with a display, processor(s), and memory detects a first user input to zoom in on a respective portion of a first video feed displayed on the display, and, in response, performs a software zoom function on the respective portion of the first video feed to display the respective portion at a first resolution. The electronic device determines a current zoom magnification and coordinates of the respective portion of the first video feed, and sends a command to the camera to perform a hardware zoom function on the coordinates of the respective portion according to the current zoom magnification. The electronic device receives a second video feed from the camera with a field of view corresponding to the respective portion, and displays, on the display, the second video feed in the video monitoring user interface with a second resolution that is higher than the first resolution.
