If your camera supports zoom function, please click the "Direction" button at the bottom of the live video screen to realize the zoom function, and then a "1.0x" multiplier will appear at the bottom left corner of the video streaming screen (default 1.0x). It can be realized by clicking 28 times/long press the function button.
Maximum support zoom to 3.0x, minimum 1.0x, zoom to the maximum value, the image clarity will be slightly affected.
