If you want to let the camera zoom in and focus on a specific place when live viewing your camera, the 3D zoom function is designed to meet your need.
Note: Please log in to your camera on a web browser first.
Step 1. Log in to your camera and click the drag-down menu of PTZ at the sidebar.
Step 2. Click the 3D Zoom button. Then press down the left mouse button, and move the mouse to drag a rectangle on the area where you want the camera to zoom in.
Step 3. Release the mouse. The camera will zoom in and focus automatically on the area you drew.
Tips: You could slide the slider on the Zoom bar to the "-" side so that the camera will zoom out.
