The image, for example a company logo, is used to provideextra information or to mask a part of the image.Since it is static, the position and size of an overlay image will remain the same regardless of resolution and Pan/Tilt/Zoom movements.Use a privacy mask to set up a dynamic mask which will always mask the specified part of monitored area.For more information about privacy masks, see Privacy Mask on page 21.To use an overlay image, the image must first be uploaded to the Axis product. The uploaded image should be a Windows 24-bit BMPimage with maximum 250 colors. The image width and height, in pixels, must be exactly divisible by 4 and cannot be larger than themaximum image resolution. If combining text and image overlays, take into consideration that the text overlay occupies 16 or 32pixels in height (depending on the resolution) and has the same width as the video image.To automatically scale the image to the resolution used by the Axis product, select the option Scale with resolution from theTransparency Settings page which is displayed when uploading in the image.To upload an overlay image:1.
