VIQS is an abbreviation of Variable Image Quality on Specified area and is a feature that enables you to change the images of a specified area.
It is possible to enhance the image quality of the specified range within a shooting area (image).
It is also possible to moderate the image data size by lowering the image quality of other areas.
The VIQS setting is available only for H.264 images.
Up to 8 VIQS areas can be set.
To check the image after configuring VIQS, when H.264 images are selected under “Stream”, you can check the image by pressing the [Confirm] button. You can also check by displaying an H.264 image on the “Live” page.
