As high-megapixel cameras become more mainstream, it not only means clearer and higher-quality videos, but also a larger coverage area for cameras. You can select an area of a camera’s field of view as a virtual camera, and also view physical and virtual cameras from the view management page for easier monitoring.

To add a virtual camera, go to QVR desktop > “Surveillance Settings” > “Camera Settings” > “Camera Configuration”. Click after adding a physical camera.

Virtual camera settings

You can define the virtual camera’s area and its size by dragging the area on the “Edit Virtual Camera Area” window, or by entering values for its area and size.

Please note: You can add up to 4 virtual cameras for a physical camera without needing an additional channel license.

After adding a virtual camera, you can click to see its information. You can also click to edit the virtual camera settings or to delete it.

Virtual camera’s application

  1. In the view management page, you can add a virtual camera to a grid.

  2. In the monitor page, you can drag virtual cameras into any window to monitor it.
